Physical Properties of Polypropylene Bags

The following text and list of properties has been gathered from various poly bag supplier websites to give you a snapshot view of poly earthbags. The information is presented here in a condensed format for brevity. It’s fun doing these blog posts because I always learn something. For instance, did you know polypropylene is 100% recyclable? That’s just one of many positive properties.

Woven polypropylene bags are designed to ship large quantities of dry product in a cost-effective manner. Woven PP bags are the most common bags in the packing industry due to their wide variety of usage, flexibility and strength. These bags are commonly used in packing fertilizers, feeds, grains, flours, salt, sugar, cement, seeds or any other palletized and powdered materials. In addition, millions of poly sand bags are used every year for flood control. Bags can be made according to your desired specifications of mesh, denier, tape width, color and sizes depending on the required capacity.

  3. Hi Owen,

    You gathered all the properties of woven polypropylene bags. Maybe you should add the word “woven” into your title. Because there’re many kinds of polypropylene bags. And only woven polypropylene bags are used in earthbag building.

    • Yes, you are correct. Most of the time I leave out the word ‘woven’ because we’re talking about rice bags, sand bags, grain bags that everyone knows about.
