Polyethylene bags are made from the polymerization of ethylene gas. This process produces a dura ble, lightweight, thermoplastic polymer consisting of long hydrocarbon chains. The degree of branching in the chains determines the properties and structure of the polymer. High-density polyethylene (HDPE) has minimal branching, while low-density polyethylene (LDPE) has much more branching.
What Are Polyethylene Bags?
Polyethylene bags are plastic bags made from polyethylene or polypropylene materials. They are durable, pliable, and customizable, making them an ideal option for packaging and protecting parts, products, and merchandise. Polyethylene bags are available in various sizes, shapes, and thicknesses to suit various applications. They are an excellent marketing tool as they can be custom printed with company logos and branding messages.
Polyethylene is classified into different types based on its molecular weight and structure:
- HDPE Poly Bags: High-density polyethylene bags are the most robust and most durable type of polyethylene bag. They are less flexible than LDPE bags but can withstand more wear and tear. HDPE bags are ideal for packaging or containing heavier items that do not have sharp edges. Thanks to its high tensile stress, HDPE is frequently used to make both small and large garbage can liners ideal for various heavy applications. At BagBarn, we offer HDPE liners that are star-sealed for extra strength, feature a convenient coreless roll, and come in a full range of sizes.
- Low-density polyethylene (LDPE) bags: Low-density polyethylene bags are thinner, more flexible, and less durable than HDPE bags. They have a better puncture resistance than HDPE but have less tensile strength than LLDPE. As such, recycled LDPE makes thicker trash can liners compared to other types of poly material. This makes LDPE an excellent choice for heavy-duty applications.
- LLDPE Poly Bags: Linear low-density polyethylene is a type of copolymer. It has properties that are between those of LDPE and HDPE. It is less crystalline than HDPE and has higher melting and softening points. An LLDPE bag has better puncture resistance than HDPE and a much softer feel. These bags are suitable for light applications such as office trash cans and more demanding ones like leaf bags and institutional or industrial waste. It can also handle large waste bags with lightweight refuse with sharp edges.
Are Polyethylene Bags Right for You?
Polyethylene bags offer many benefits, but they may not be the right choice for every application. Here are a few things to keep in mind when deciding whether the polyethylene bags are right for you or not:
-
- Cost: Polyethylene plastic bags are generally less expensive than other types of packaging, such as corrugated cardboard boxes, and can be a suitable option if you’re trying to reduce costs. However, the cost of polyethylene varies depending on the density and thickness of the material.
- Transparent packaging: Polyethylene bags offer a clear, unobstructed view of the products inside. This can be helpful if you want to showcase your products in their packaging without opening the bag.
- Strength: While polyethylene bags offer some protection from impact, they’re not the best protective packaging. As such, they may not be the best choice for products susceptible to breakage.
- Recyclable: Despite their reputation, all polyethylene bags are recyclable because they can be made with degradable additives. Reusing plastic bags will lower their carbon footprint and when combined with the low cost, offer an ideal solution for most businesses.
