Low Density Polyethylene

When you hold a product in your hand at your point of purchase, you probably don’t think much about the molecular buildup of the packaging. You probably don’t give much thought to the density of the polyethylene bags which hold your products, either. These factors matter more than you may realize. At Rutan, we have over 50 years of experience manufacturing polyethylene bags and we are happy to explain why this concept is important to understand when ordering flexible packaging for your products.

Each year, more than ten million tons of polyethylene is produced. Making it one of the most widely produced plastics in the world  Polyethylene is a thermoplastic polymer with variable crystalline structure and an extremely large range of applications depending on the particular type. Although there are several types of polyethylene structures, the two most popular are high and low density.

High Density Vs. Low Density

Polyethylene manufacturing processes are categorized into “high pressure” and “low pressure” operations. The high pressure produces low density polyethylene (LDPE) while the low-pressure process makes the high-density version.

Low density bags are thick, flexible and highly resistant to puncturing and tearing. They are ideal for use in sandwich bags, individual product packaging bags, and similar products. Even trash bags which may be filled with sharp, jagged or irregular shaped items would be best used with a low-density polyethylene.

On the other hand, high density bags have a different manufacturing process than low density bags, making them thinner and not as puncture resistant. However, they can still hold many types of products, especially heavy items, so long as they are not rough edged and likely to puncture.
