Polyethylene (PE) vs Polypropylene (PP)

*Updated 02-15-18*

Plastics can be complicated and confusing as to which material is best for your bagging application. Like we know, all packaging isn’t the same and different applications call for different poly bags. Below we list some of the most important differences between Polyethylene and Polypropylene material.

Polyethylene bag

Polyethylene (PE)

Polyethylene is flexible, durable and tear-resistant. These three characteristics are extremely important when you’re putting heavy items in your poly bag. Industrial companies use polyethylene storage bags for large heavy items such as industrial machining parts.


  • Inert, translucent and creates a lower static charge
  • Prohibits a the greater amount of light to enter the bag which protects the contents
  • Attracts much less dirt, dust and other foreign, organic elements
  • Soft and pliable
  • Higher purity (100% Virgin)

Polypropylene bagPolypropylene (PP)

A polypropylene bag is a high clarity, crystal clear bag which enhances the product’s image. It provides a highly protective barrier against moisture and vapors. These poly bags delay evaporation and dehydration to preserve freshness and taste of packaged foods. Polypropylene bags are great for the following industries; food, electronics manufacturing, hospitals, and agriculture.


  • Crystal clear for great product presentation
  • Stiff and hard plastic
  • Rough surface has the potential to produce scratches
  • Outstanding vapor and moisture barrier.
  • Meets FDA and USDA specifications.

Polyethylene (PE) and Polypropylene (PP) are used in more than just poly bags. From stretch film to tape, plastic sheeting to strapping; plastic is everywhere. Check out the links below to shop our products and see how we can help you.
