Here is everything you need to know about corrugated boxes.
You will learn:
A corrugated box is a disposable container crafted from multiple layers, typically including an inner, outer, and a mid-layer. The middle layer features a wavy, fluted design, providing both cushioning and structural support for heavier contents. This design significantly bolsters the box's resilience and impact absorption capabilities, making it an excellent choice for safeguarding products during shipping and storage.
The standard cardboard box has a history exceeding two centuries. The process of incorporating flutes for corrugation began in the midst of the first industrial revolution. Since its invention, the corrugated box has evolved into the predominant type of shipping container, integral to every facet of logistics and material handling.
Although the process of manufacturing a corrugated box might appear straightforward, several critical factors must be evaluated before production begins. As with all packaging materials used for shipping, storage, and product protection, corrugated boxes are meticulously designed and engineered to define their capacity, stacking strength, shipping durability, and printing compatibility. Optimizing these attributes ensures reliable performance throughout supply chain logistics, retail, and e-commerce fulfillment.
The initial stage in the production of corrugated packaging involves assessing various key elements: box construction, flute profile, burst strength (Mullen Test), edge crush strength (ECT), flat crush strength, basis weight, paper weight, and the types of coatings or surface treatments applied. These factors influence not just how well the box protects its contents, but also its suitability for specific industries—from food packaging to electronics shipping—and its recyclability and cost-effectiveness.
A corrugated box can have one of three wall configurations: single-wall, double-wall, or triple-wall. The type of wall design directly impacts the box’s ability to withstand heavy loads and protect against crushing, making the correct selection essential for optimal packaging performance and compliance with shipping regulations.
Single Wall - This is the simplest and most common corrugated wall design, consisting of a single outer layer, a single inner layer, and a fluted medium sandwiched between the two. Single-wall boxes are widely used for lightweight shipping, product display, and retail packaging due to their cost-effectiveness and versatility.
Double Wall - The double wall design adds an additional layer of fluting and liners to produce a box capable of handling heavier, bulkier, or fragile items. Double-wall corrugated boxes offer enhanced protection against crushing and punctures, making them ideal for industrial packaging, electronics shipping, and long-haul transportation.
Triple Wall - As the name implies, triple-wall corrugated boxes have three layers of flutes separated by four liners. Each layer uses differently sized flutes for added stability and increased compression strength. Triple-wall boxes maximize cushioning and protection, and are commonly used for shipping heavy machinery, automotive components, or other high-value goods that need the ultimate in transit protection.
Corrugated boxes typically feature one of five standard fluting types: A, B, C, E, and F. While these are the common types, manufacturers and packaging designers have the flexibility to create custom fluting profiles. These custom versions can include combinations of the standard types or entirely unique flute geometries that optimize cushioning, stacking strength, crush resistance, and printability according to the specific needs of the application.
In addition to the five standard flute types, there are specialized flutes that combine or fall between the standard flutes, such as D flutes. Specialty flutes like EE, EF, and BC are commonly used in double-wall profiles for enhanced stacking strength and unique applications. Rarely used flutes like N and O are extremely small, measuring less than half a millimeter in height—these are sometimes used in micro-packaging and specialty retail packaging.
Choosing the appropriate flute type is a critical decision for businesses, as it influences shipping performance, cost, print results, and sustainability. Consult a packaging engineer or corrugated manufacturer to select the best flute for your specific product or distribution needs.
The burst strength of a corrugated box refers to the amount of force the material can withstand before it ruptures, cracks, or falls apart. The Mullen Test, developed over 130 years ago, applies force to the face of the corrugated material until it bursts. Results are given in pounds, indicating the force per square inch the material can handle. For instance, a box rated at 200# can withstand 200 pounds (90 kg) of force per square inch. This standardized test helps assign a burst strength grade to the box, which is crucial for regulatory compliance and quality assurance.
The Mullen Test provides insight into how well a box will endure handling, drops, and rough shipment, including assembly operations and transit through distribution channels. It helps predict the box's resistance to punctures, accidental impacts, and damage as it moves through warehousing and logistics facilities.
However, the Mullen Test has limitations, as it does not account for the contribution of the fluted medium to the box's strength, especially in stacking scenarios. Although the fluted medium is crucial—contributing about 50% of a box's overall compression and stacking strength—it isn't reflected in the burst strength measurement. This is where the Edge Crush Test (ECT) becomes valuable for modern corrugated packaging assessment.
The Edge Crush Test (ECT) measures the vertical compression strength of a corrugated box, providing crucial insight into how well it will hold up when stacked on pallets, racked in warehouses, or packaged for long-distance shipping. This test is a practical, reliable indicator of a box's ability to maintain structural integrity under pressure and frequent handling. Unlike material characteristic tests, the ECT is considered a “performance-based” property test and is now the preferred metric for most shipping boxes in North America.
Several factors can influence the ECT rating of a box, including humidity, storage duration, the amount of compression endured during manufacturing, and pallet stacking patterns. For example, a box with an ECT rating of 55 can withstand 55 pounds (25 kg) of pressure before it collapses. ECT ratings such as 32 ECT, 44 ECT, and 55 ECT help packaging buyers select the right carton for their shipping weight and stacking requirements, thus reducing damages and returns.
The basis weight refers to the weight of the raw cardboard sheets before they are converted into corrugated boxes. It is measured in pounds and represents the weight of a ream (typically 500 sheets) of paper at a specific standard size. Since paper comes in various thicknesses and grades, basis weight helps manufacturers and buyers compare board quality, strength, and rigidity. Higher basis weight generally indicates stronger, more robust boxes suited for heavy-duty shipping and industrial applications.
When sourcing packaging, knowing the basis weight is essential for cost estimation, sustainability (recycled content), and compliance with carrier shipping standards.
The paper weight of corrugated cardboard is determined by the thickness of the papers (liners and fluting medium) used in manufacturing. It is typically measured in pounds per thousand square feet (M weight) or as a calculated board grade, and commonly ranges from 26 lbs to 42 lbs (11.8 kg to 19 kg). Understanding paper weight is important for custom packaging buyers looking to balance cost, sustainability, and protective performance in a corrugated box.
In the manufacturing of corrugated boxes, various coatings and finishes are applied to enhance the box’s durability, moisture resistance, and appearance. The primary types of coatings used are aqueous coatings and UV coatings, both of which play a significant role in protecting custom-printed packaging, food and beverage packaging, and shipping cartons from wear and environmental conditions.
Additional specialty coatings—such as anti-static, grease-resistant, or water-repellent finishes—are available based on specific market or regulatory requirements for pharmaceutical, electronics, or food packaging.
The equipment used to manufacture corrugated board, called a corrugator, is at the heart of modern packaging production. The core components of corrugated board include liners (the flat outer layers), typically made from long-fiber softwood kraft paper, and the flute (the corrugated middle layer), generally formed from short fibers sourced from hardwood trees. This combination ensures both box strength and optimal cushioning properties.
Large rolls of containerboard are processed in a single-facer machine, which creates the fluted structure by heating the paper with steam to approximately 338°F (170°C). An adhesive—usually a starch-based, environmentally friendly glue—is then applied to the peaks of the flutes, bonding the fluted medium to a liner sheet. This creates a single-faced web, which is the basis for all corrugated packaging.
Once the single-faced web exits the single facer, it proceeds to the double glue unit and double backer to form multi-wall structures. To create double-wall corrugated paperboard, two single-faced webs are introduced along with the liner into the double glue unit. Adhesive is applied to each exposed flute tip to bond the outer liner. Throughout this process, heat and precise tensioning ensure proper adhesion, strength, and board flatness.
Following lamination, the corrugated board is dried, scored (to facilitate folding), and cut to the required dimensions by a high-speed slitter-scorer and a rotary die-cutter.
The result is a large array of corrugated sheets, which are then staged for box manufacturing. Based on customer requirements, these boards are custom-printed with branding, product specifications, or handling instructions using advanced flexographic or digital printing technologies, ensuring high-quality graphics and critical compliance information for retail or transit packaging.
The corrugated boards—now scored, printed, and cut—move through a sophisticated folder-gluer or box-making line. Here, they are processed through a trimmer to create custom flaps, die-cut handles, or complex box architectures for specialty packaging. High-speed machinery can produce up to 90 finished boxes per minute, ensuring cost efficiency for high-volume packaging operations.
After trimming and die-cutting, the boxes proceed to a folding machine, which makes precise folds along scored lines and applies adhesive or gluing tapes to permanently seal flaps. Modern folder-gluer lines can also integrate special features like tear strips, tamper-evident closures, and window cutouts, providing value-added solutions for ecommerce packaging, food delivery cartons, and luxury retail boxes.
The entire workflow—including cutting, printing, slotting, assembly, and quality inspection of corrugated board into a finished box—ensures adherence to industry standards such as ISTA (International Safe Transit Association) and makes corrugated packaging the gold standard in sustainable, recyclable, and customizable solutions for businesses worldwide.
Choosing the Right Corrugated Box: For businesses or individuals seeking custom packaging solutions, partnering with a reputable corrugated box manufacturer or supplier can help optimize packaging for cost, sustainability, branding, and freight savings. Be sure to consider key factors such as required box strength (ECT or Mullen), flute type, wall construction, basis weight, printing needs, and specialty coatings to best protect your products and enhance the customer experience.
Often regarded as the standard shipping container, the corrugated box is a fundamental tool for manufacturers when it comes to transporting their products. Due to their customizable design, corrugated boxes are one of the most versatile and widely used shipping solutions available.
These boxes are well-known for their durability and their ability to cushion and protect delicate items during transit. The versatility of corrugated boxes allows them to be tailored to meet a wide range of shipping requirements.
Another key advantage of corrugated boxes is the option to print on them, including incorporating a company’s logo. Having a clear and attractive logo on the boxes helps in brand promotion and enhances brand recognition. Using boxes as a medium for branding is a cost-effective method to make a company's identity stand out.
During the production of corrugated boxes, a glue composed of water and starch is utilized to bond the flutes and liners. This choice of adhesive helps prevent contamination of fresh produce, such as fruits and vegetables. Corrugated boxes offer several advantages for food shipping, with safety and resistance to bacterial growth being paramount. Research has demonstrated that corrugated boxes are effective in maintaining the freshness of food for extended periods.
When shipping or storing office supplies, particularly paper products, a primary concern is the potential for damage during transit or while on shelves. Corrugated boxes are designed to address this issue by providing both strength and cushioning, thereby minimizing the risk of damage and ensuring that office materials remain in good condition.
In e-commerce, corrugated boxes play a crucial role in maintaining an efficient and agile supply chain, which is essential for the industry. Over the past two years, their use has surged as they become central to e-commerce logistics. A significant challenge in this sector is shipping smaller quantities to a diverse array of destinations. Corrugated boxes provide the necessary security and protection required by the e-commerce sector, meeting the demands for safety and reliability.
The surge in online shopping has driven a significant increase in the use of boxes for shipping textiles. Considerable investments are being made in packaging solutions to ensure safe, dependable, and intact delivery. Since customer satisfaction is vital for retaining clients, corrugated boxes have become crucial in meeting consumer expectations.
Research indicates that over 50% of customers are likely to return to a company if their textile orders are well-packaged. Corrugated boxes allow textile manufacturers to customize packaging to both the product and the consumer, fostering repeat business and enhancing customer loyalty.
When shipping electronics and electronic components, selecting the right packaging is crucial due to the delicate nature of these items. Improper packing can easily result in damage. Corrugated boxes are commonly used in conjunction with additional packing materials to provide extra protection. The primary concern is the stress exerted on components during handling, which can cause circuit damage or loose connections. The cushioning inside corrugated boxes helps mitigate these risks, ensuring that electronic products arrive safely and in excellent condition.
Similar to the electronics industry, healthcare materials require careful handling and packaging. Sensitive medical instruments are prone to damage from inadequate packaging and rough handling. For medications, specific shipping conditions must be met to ensure their safety and efficacy. The diverse range of corrugated boxes available allows pharmaceutical companies to confidently ship their products, ensuring that medications remain well-protected and secure throughout transit.
Shipping materials for the battery industry must adhere to rigorous safety and regulatory standards. The fiberboard used in these custom-designed boxes complies with industry guidelines for corrugated packaging. In addition to specialized liners, each battery shipping container must be clearly labeled with relevant safety instructions and content information to ensure proper handling and legal compliance.
Shipping auto parts demands meticulous preparation due to the diverse sizes and shapes of the components. The primary objective is to ensure that each part is adequately protected from damage during transit, which involves selecting packaging that is robust, capable of supporting weight, and provides cushioning.
The choice of container largely depends on the specific auto parts being shipped, ranging from small items like lug nuts to larger components such as carburetors. Larger parts require boxes that are durable enough to withstand handling without rupturing. Manufacturers and suppliers often use charts to recommend suitable box types for various parts.
Supplying shipping materials for military use involves adhering to specific Mil-Spec regulations. Unlike standard industrial practices, the military outlines precise requirements and production methods for the materials they utilize. The primary mandate for military-grade boxes is their robustness.
In addition to being durable, these corrugated boxes must be engineered to endure various environmental conditions, including high humidity, extreme temperature fluctuations, and exposure to moisture. Military shipping materials are designed to provide superior protection for sensitive and technical equipment while complying with the American Society for Testing and Materials (ASTM) standard D5118.
Corrugated and solid fiberboard boxes, sleeves and liners are used to unitize products into packages of size and shape suitable for manual or mechanical handling and to protect the contents against environmental, handling, shipping, and storage conditions.
The primary focus is on safeguarding the contents and ensuring their security.
For publishing houses, shipping books, documents, magazines, and other printed materials presents the challenge of weight, as large volumes of printed items can be quite heavy. After addressing the weight issue, moisture becomes a significant concern since it can cause severe damage to printed materials.
While corrugated boxes come with protective coatings on the exterior, it's crucial to add an extra layer of defense against moisture by lining the inside of the box with plastic or a similar wrapping material. An effective approach is to opt for boxes made with triple-ply fiberboard for enhanced protection.
Corrugated boxes are crafted from corrugated fiberboard, which is available in various thicknesses and grades. For optimal quality, the fiberboard used should consist of top-grade paper and well-formed fluting.
Corrugated fiberboard is produced by bonding fluted sheets between flat linerboards. Its structural benefits, versatility, and environmental sustainability have made it a crucial material in the supply chain across numerous industries.
Single wall fiberboard consists of a single layer of fluting sandwiched between two liners. The most commonly used flute profiles for single wall fiberboard include A, B, C, E, and F, with B and C being the most frequently utilized.
Double wall corrugated fiberboard essentially consists of two layers of fluting sandwiched between two liners. Unlike single wall fiberboard, which has only one set of fluting, double wall fiberboard features two sets of flutes separated by an additional medium. Common flute combinations for double wall fiberboard include AC, BC, and EB profiles.
Triple wall fiberboard, as its name suggests, incorporates three layers of fluting. Unlike single and double wall fiberboard, where the fluting is typically uniform, triple wall fiberboard may feature fluting lines of different sizes and configurations. The exterior layers are covered with liners or facings, while the layers between the flutes are known as the medium.
While the thickness of fiberboard plays a crucial role in its strength, the type of paper used for the liners and flutes is equally important. Various types of paper are employed for the liners in corrugated fiberboard, including Kraft, test papers (grades 2 and 3), chip, bleached white, white top, mottled Kraft, oyster, semi-chemical, and waste-based papers.
Kraft paper or paperboard is manufactured through the Kraft process, which removes lignin—a natural bonding agent in wood—using sodium sulfate. This process enhances the paper's strength and durability, as Kraft paper is known for its high tear resistance. Made from softwood pulp, Kraft paper benefits from long fibers that further contribute to its robustness and resilience.
To produce bleached white paper, Kraft paper undergoes a treatment involving bleaching agents and various chemicals. This process removes impurities and whitens the Kraft pulp, resulting in a cleaner and stronger paper.
This treatment enhances the paper’s strength, making it suitable for packaging heavier items. Kraft bleached white paper is renowned for its rigidity, durability, and overall strength.
Test 2 paper liner is made from a blend of recycled materials and resembles Kraft paper in most respects, but it has lower burst strength. Consequently, it is typically used as an outer liner where resistance to punctures and moisture is not critical.
Test 3 paper is composed entirely of recycled materials and features a double-layer structure, also known as duplex. While it is not as robust as Kraft paper due to the lack of virgin fibers, it is commonly used as an inner liner.
Test liners generally offer less strength than Kraft liners due to their higher recycled content. These liners come in various grades and classifications, which can vary based on their country of origin.
Chip liners are produced from recycled materials that are less controlled, resulting in a lower quality compared to other liners. Consequently, they do not provide the same level of performance as higher-grade liners.
Semi-chemical fluting is made from hardwood with short fibers. This paper pulp undergoes minimal lignin removal, resulting in papers with high density and excellent compression strength.
During the corrugation process, the heat treatment helps form rigid fibers as the paper cools, enhancing its resistance to crushing.
Fluting is often manufactured using waste-based materials due to their superior properties. This type of fluting is created from 100% recycled paper, which is treated with chemicals and reinforced with starch. The starch serves as a replacement for the natural lignin found in hardwood and softwood pulps.
The development of waste-based fluting medium addresses environmental concerns and promotes the recycling of materials. Most fluting used in the production of corrugated fiberboard is derived from waste-based sources.
Fiberboard grading employs two widely accepted methods within the corrugated fiberboard industry. Understanding these grades is crucial for selecting the appropriate fiberboard for specific applications.
The Mullen burst test is a long-established method for evaluating fiberboard and is widely utilized by corrugated fiberboard manufacturers. It is the oldest testing technique and reports its results in pounds.
In the Mullen test, a sample of corrugated fiberboard is secured in a testing apparatus. A hydraulic arm exerts pressure on the sample via a rubber diaphragm. This force is increased incrementally, either manually or electronically, until the diaphragm punctures the fiberboard.
The Mullen grade reflects the fiberboard's resistance to bursting, with results expressed in pounds. For example, a Mullen test result of 32# indicates that the fiberboard sample withstood a force of 32 lbs. (14.5 kg) before bursting.
With the increased use of corrugated boxes and the growing number stacked on pallets, it has become crucial to assess how much weight a corrugated box can endure from other boxes. To evaluate this, the Edge Crush Test (ECT) was developed, providing both Mullen and ECT ratings for corrugated fiberboard.
Similar to the Mullen test, the ECT involves testing a sample of corrugated fiberboard. However, the ECT applies force to the fluted edge of the sample to measure its resistance to crushing. The result is a numerical value indicating the fiberboard's capacity to withstand compression along its linear edge.
| Mullen and ECT Test Results for Single Walled Corrugated Fiberboard | ||
|---|---|---|
| Mullen Burst Strength | Edge Crush Test (ECT) | Max. Weight Limit/carton |
| 125 # | 23 ECT | 20 lbs. |
| 150 # | 26 ECT | 35 lbs. |
| 175 # | 29 ECT | 50 lbs. |
| 200 # | 32 ECT | 65 lbs. |
| 275 # | 44 ECT | 95 lbs. |
| 350 # | 55 ECT | 120 lbs. |
Coatings for corrugated boxes must comply with recycling and composting requirements. The box manufacturing industry strives to create coatings that meet these criteria. Contrary to the assumption that coatings are only applied to the outer surfaces of boxes, they are also applied to liners and paper, ensuring that the entire board remains recyclable and compostable.
Conductive: Conductive coatings are designed to shield against electrostatic discharge (ESD). These coatings are easy to handle and fully recyclable, offering protection from static electricity.
Waterproof: Waterproof coatings not only protect against water damage but also resist oil, grease, and vapors. These coatings often have a waxy appearance and are used for carrying industrial items and food products, meeting the Food and Drug Administration (FDA) standards for handling greasy or oily materials.
Color: Color coatings can be applied in various shades to align with branding needs. After applying the color coating, additional branding information can be printed on the box.
Scuff Resistance - Scuff-resistant coatings are sturdy and abrasive resistant. They are designed for packaging products that may damage the facing of the box during shipping. A strong scuff-resistant box eliminates the need for additional packaging material such as bubble wrap or Styrofoam.
Corrosion Protection (VCI): Volatile Corrosion Inhibitors (VCI) are used in packaging to prevent corrosion. This additive is infused into the corrugated board, providing ongoing protection even if the packaging is opened. VCI-coated boards are particularly useful for shipping ferrous metals.
Ultraviolet (UV): UV coatings protect against the harmful effects of ultraviolet rays, which can damage chemical bonds in products. These eco-friendly coatings offer robust protection against UV light and can be applied to corrugated boards to shield products from sun damage.
Corrugated boxes are versatile and can be crafted to accommodate a wide range of shipping needs, resulting in thousands of variations in shapes, sizes, thicknesses, and designs. This variety also extends to customized boxes tailored to specific requirements.
Despite the vast number of box types, they all share fundamental attributes from which more complex designs are derived. A typical corrugated box includes essential elements such as a lid, top, sides, bottom, and internal space. These core components form the basis of all box designs, and modifications to these elements result in the diverse array of box types available.
It is generally assumed that all corrugated boxes are built to be sturdy, durable, and long-lasting, having been designed and manufactured to fulfill specific needs and meet predetermined conditions.
A slotted box is crafted from corrugated fiberboard that is pre-scored and slotted, allowing it to be folded into shape to create a corrugated container. Among the various box types, slotted boxes are the most prevalent and versatile. They are commonly used for shipping and storing a wide range of products, chemicals, and parts.
The term "slotted box" covers a variety of box designs, each with specific characteristics and uses, as detailed below.
Telescope boxes are named for their design, which features two separate, foldable parts: the body and the cover. The body forms the main part of the box that holds the item, while the cover acts as a lid that fits over the body. When assembled, the cover and body overlap, creating a secure container for shipping and storage.
A rigid corrugated box is constructed from three components: two end panels and a central body. The end panels are folded into place at the ends of the box, while the central body piece folds together to complete the structure. The rigidity of the box is provided by the flaps or joints that secure the box's shape.
In the self-erecting variant, a single sheet of scored corrugated fiberboard is designed to fold into a slotted or telescope-style box. This type of box can be quickly assembled into its final form without additional assembly steps.
Folder corrugated boxes are like the self-erecting rigid type. They consist of one piece of corrugated fiberboard that has been scored so it can be folded together. The types of folders include one piece, five-panel, and tray.
The single-piece box features a flat base with flaps that fold to create the sides and ends, while the extensions of the side flaps form the top. In the five-panel design, the panels fold in a single direction, with the second and fourth panels serving as the top and bottom, and the fifth panel acting as a side. Trays are available in both five-panel and four-panel designs; the five-panel tray includes a top, whereas the four-panel version does not.
The tucktop corrugated box is designed for quick and easy assembly. This box comes pre-glued, starting out flat with the bottom tucked into the box's body and the top flaps extended. To set it up, simply open the sides of the box, which causes the bottom to flatten, making it ready for loading. The box assembles swiftly in one motion.
A variant of this design is the tucktop snap lock bottom box. Unlike the tucktop, this version does not have a pre-glued bottom. Instead, the bottom is formed by folding four flaps together. The primary differences between these two types are the setup time and the associated costs.
A double cover corrugated box features a body shaped like a square or rectangular tube, with interchangeable telescopic covers for the top and bottom. These components are kept flat until needed. To assemble, the telescopic covers are fitted onto the tube, which then opens to accommodate the covers.
There is also an interlocking variant of the double cover box, which offers a more secure fit. This version includes interlocking flanges on both the covers and the tube, enhancing the box’s strength. It is specifically designed for shipping heavy items, such as appliances and heavy equipment.
Creating corrugated board starts with pulping wood fibers, which are then processed to form the corrugated structure. This initial processing, known as virgin corrugation, uses only fresh fibers without any recycled material.
Once virgin corrugated board has been utilized to its maximum potential, it undergoes repulping up to five times before it is no longer viable. With each repulping cycle, the fibers become shorter and weaker. The outcome of this process, combined with the production of new virgin board, is recycled corrugated board.
Upon examining the various aspects of corrugated boxes, their significance as a shipping solution becomes apparent. Their primary benefit lies in their robustness and resilience, despite being constructed from molded paperboard and adhesive. These boxes are engineered to endure diverse environmental conditions, ranging from incessant rainfall to intense heat. This adaptability is why corrugated boxes play a crucial role in global shipping logistics.
Corrugated boxes are highly effective in preventing moisture and bacterial contamination. They provide a reliable cushioning effect and can be sized to fit a wide range of products.
These boxes ensure that items remain secure during transit, shipping, and handling. Adjustments in corrugated protection, including varying thicknesses and sizes, allow for extra care when shipping delicate and fragile items.
The corrugated fluted medium offers a lightweight yet protective layer. Corrugated fiberboard excels in shielding contents from environmental factors and handling damage. Compared to wood or plastic, it is lighter, more cost-effective, and easier to recycle, making it a more sustainable choice both environmentally and economically.
Although corrugated boxes come in standard sizes and shapes, they can be tailored to meet various specific requirements. Customization extends to having logos and designs printed on the box's sides, top, or bottom.
Various coatings, treatments, adhesives, and flame-resistant options can be applied to corrugated boxes. They are available in numerous sizes and can be easily folded into various shapes to ensure a perfect fit.
High-quality custom designs make products stand out. Well-designed shipping materials enhance a company's operational values and brand strength. An innovative and well-crafted corrugated box design helps establish a strong, lasting brand presence.
