  • Polyethylene Bags VS Polypropylene Bags

    Among the materials used to create plastic bags in their many forms is polyethylene, one of the major plastic bag substances. Polyethylene bags have many positive characteristics that are very similar to the other major poly bag substance, polypropylene. The major difference between the two is that polyethylene produces a translucent plastic film, while polypropylene is completely clear. For this reason alone, some industries prefer one over the other. The reasons why some industries prefer polyethylene bags over polypropylene bags are discussed below. Polyethylene is flexible, tear-resistant and durable, all...

  • Plastic Merchandise Bags: Not Just For Shoppers

    It is often assumed that plastic merchandise bags and plastic shopping bags are the same item, both of which come in a variety of styles, sizes and colors. The specific details of shopping or merchandise bags depend on the store that is purchasing them for their customers. However, plastic merchandise bag is a term not only applied to the bags that cashiers place products in when they are purchased by an individual consumer but also refer to the packaging products come to the store within. These plastic bags are therefore...

  • Polyethylene Bags: Choosing Style and Thickness

    The material currently used for more than fifty percent of all films is polyethylene; and most poly bags are made from low density polyethylene (LDPE). This specific kind of polyethylene is relied on for the manufacturing of bags because of its superior tensile strength, clarity, flexibility, and water barrier as well as the fact that it is also resistant to most caustic compounds. Some other advantages of polyethylene bags include quick lead times in manufacturing, high quality packaging at low cost, a wide range of printing options, great moisture protection,...

  • Finding A Compromise For Plastic

    Everyone is familiar with the recent push to move from plastic bags to canvas bags in grocery stores. The recycling movement and the push to go green have really shaped how many people live their lives. Schools are attempting to meet certain green regulations, recycling is a normal thing, and most people are extremely conscious of how their actions affect the environment. Promoting carpooling and riding bikes to work is commonplace, and plastic bag bans are in place in some cities. One thing that is thought to put a damper...

  • Poly Presentations

    Christmas brings with it candy, most of it homemade. People go out of their way to make fudge, dip peanut butter balls in chocolate or caramelize popcorn. Some of these candies are eaten at home, but most make their way onto the plates and into the hands of friends. When a plate with plastic wrap over it just isn't enough, polyethylene bags come through with a fancy, practical application. Throw out the paper and Styrofoam plates - they bend and allow treats to slide around. A better option is a...

Industry Information

Polyethylene Bags

Polyethylene bags are waterproof, translucent plastic receptacles employed in a number of industrial, commercial and domestic settings for the protection, storage or transport of goods. Food, chemical, defense, waste management, retail, medical, construction and myriad other industries utilize these poly bags in daily operations. Although polypropylene bags are a common and more economic alternative to the use of polyethylene, the latter holds several advantageous properties making them more popular.

Perfect for food storage, waste removal, bin liners, packaging and shopping bags, polyethylene bags are flexible and tear resistant. Additionally, bags composed of this material are moisture resistant, anti-static and prohibit the passage of large amounts of lights making them ideal for archival storage of artifacts and prints. The bags are also inert. This means that they are not readily reactive with other elements and thus able to hold variable contents without risk of damage or contamination to the bag or object. To suit such variable needs, a wide array of polyethylene bags are readily available and customization if common. Plain, sealable, tamper evident and custom printed bags come in any number of sizes, shapes and capacities. It is important to consider the intended use of these baggies prior to purchase to avoid costly errors.  


The base material of polyethylene bags is ethylene, a derivative of natural gas or petroleum. These plastic resins undergo polymerization which links together a series of monomers to from a polymer or plastic. The resulting thermoplastic can be one of many different categories within the polyethylene family. Distinctions are made based upon molecular weight and branching or crystallization. High density polyethylene (HDPE) is a non-porous and non-stretching variety that offers the best temperature and moisture resistance and is the cheapest option. Low density polyethylene (LDPE) is more expensive but offers improved clarity and resistance to tearing as its porous nature allows it to stretch.  Additional types of polyethylene include linear low density polyethylene (LLDPE), the new-generation metallocene, ultrahigh molecular weight polyethylene (UHMWPE), medium density polyethylene (MDPE) and very low density polyethylene (VLDPE). Each material has its own particular strengths and weaknesses in relation to the composition of plastic bags. To create these bags, resin beads are heated between 180 and 240 degrees Celsius and then extruded into a thin film through sheet or blow film methods. Winding and casting may also be used to this extent, but are far less popular. Once cooled, the thin, flexible film is flattened by rollers. Additional processes include cutting and sealing into the desired bag shape. Finishes such as painting or the addition of handles and zippers follow.
