Vinyl is a type of plastic made from ethylene, which is found in crude oil, and chlorine, which can be found in salt. Combining both of these substances can make polyvinyl chloride, or PVC. Vinyl is not a natural material, but is man-made and synthetic. When many people hear the word “vinyl” or “PVC,” they may think of vinyl records or large, white pipes. However, vinyl can be used to make items such as gloves, or siding and flooring for buildings.
After obtaining the chlorine and ethylene, the two chemicals are combined by way of either direct chlorination, where pure ethylene and chlorine are used, or oxychlorination, where hydrogen chloride and ethylene are used. The combination yields a liquid called ethylene dichloride, or EDC. The EDC is passed through high pressure and heat, which forms a gas called vinyl chloride monomer, or VCM. The VCM is then polymerized and converted into a PVC resin, which is in powder form. The final step involves the compounding of the vinyl resin and the addition of modifiers and additives that will alter its flexibility and other physical properties.
Vinyl can easily be made flexible, making it ideal for fabricating bags that can carry numerous types of items and withstand the elements. Soft vinyl material can be used to manufacture bags. Using vinyl materials such as polyvinyl chloride or ethylene-vinyl acetate (EVA), vinyl bags can be made in a broad range of configurations to accommodate for a multitude of applications. Many plastic bag manufacturers supply zipper bags, tote bags, vinyl pouches, drawstring bags, shopping bags, and envelopes in order to transport, store, and protect practically any item imaginable.
Applications where vinyl bags are used are in the commercial and consumer industries. Within these applications, they are used for the purposes of display, storage, and transportation of various items. One of the most popular applications for vinyl bags is product packaging. Products that are almost always packaged in vinyl bags include those that are typically sold in collections or sets, such as toys, books, or personal care items. Sealing these products in vinyl packaging protects the items from damage, and the transparency of the packaging enables consumers to see what it contains. Vinyl packaging is also used for consumer storage applications, helping to store items such as clothing, blankets, bedding, and numerous other household items.
Flexible vinyl is a highly recommended material for bags due to its numerous beneficial properties. In its flexible form, vinyl is waterproof, durable, flame retardant, and resistant to wear and tear, ultraviolet radiation, and stress. All of these characteristics enable vinyl bags to withstand both the elements and the strain of day-to-day usage, as well as protecting the items they carry. Whenever people pay a visit to a grocery store or most retail outlets, they carry their purchased items home in a vinyl bag. Vinyl bags are made to protect items such as documents, electronics, and clothing from water or UV-related damage. In addition to its physical properties, vinyl is highly inexpensive, making it a cost-effective solution for any company who wishes to use it to package their products. Items that are stored with vinyl packaging are protected from dust and pests.
In addition to bags being made from PVC, there are certain applications that call for bags that are made from ethylene-vinyl acetate, or EVA. One particular industry that utilizes EVA bags is medical. One example within the medical industry is infusion bags. EVA is resistant to contaminants, crack resistant, and maintains its flexibility at low temperatures, making the material ideal to contain and transport blood and other fluids.
In addition to their beneficial natural properties, other enhancements and features can be added to vinyl bags for optimum efficiency. The bags are naturally colorless and transparent, but you may have the option of adding various colors, textures, and transparencies to suit the needs of a particular application. In addition to aesthetic options, practical features may be added to the bags as well. Examples of these enhancements include closure and sealing options such as snap closures, slide seals, zippers, and draw strings. Hangers and handles can also be attached to the bags for easier transportation and display.
As beneficial as PVC can be, it can emit toxic compounds and can be harmful to the environment. Fortunately, there are more eco-friendly alternatives that are PVC-free. EVA, as previously mentioned, is one of these alternatives, which makes it popular for the manufacturing of bags for the medical field. Therefore, it is important to consider all types of vinyl when choosing bags for your desired application.
