WHY WOVEN POLYPROPYLENE

Simply put, woven polypropylene is the best material for making bags, especially bags which will contain large quantities of granular or small-sized products such as pet food, rice, seeds, charcoal, kitty litter, grain, cement, fertilizer, dry chemicals, powdered minerals such as gypsum, potatoes, and other similar products.

Woven polypropylene bags offer many advantages over paper and jute.:
  • Lighter weight
  • Much greater bursting strength
  • Better pest resistance
  • Resistance to tearing
  • Reusable
  • Can be air permeable and moisture, pollutants, bacteria, mildew, and oil resistant
  • Properties do not degrade if wet
  • Less expensive
For these reasons, more and more companies are packing their products in polypropylene bag. This has been especially true in the B2B arena where appearances are not as important as cost and performance.

Companies who market to the consumer have not been as quick to make the switch because paper bag has, up-to-now, been a far better medium for bright and crisp graphics. However, with our new process of three-layer bag-making, our graphics are the same as for paper bag. So now companies can enjoy the benefits of woven polypropylene bag while giving the customer hard-hitting and beautiful graphics--and all at a lower cost.
Woven propylene (PP) bags

Woven propylene has the strength necessary for packaging heavy amounts of product. Whereas paper or Polyethylene (PE) bags often break when loaded with 30 pounds or more of product, woven polypropylene (PP) can easily handle over 100 pounds. And now, with the technology available to Lucky Star, woven polypropylene (PP) bags can look just as good as bags made from other materials. Strength, durability, and appearance, all in one package.

Some of the most common uses for woven polypropylene bags include pet food, rice, fertilizer, animal feed, grains, seed, cement, wood chips, charcoal, chemicals, and sand. Basically, any product which is packaged in paper, jute, cotton, or plastic bags can be switched over to woven polypropylene (PP). The below table gives some typical bag sizes and capacities.
