Heavy Duty PE Bag for Polyester Resin

Polyethylene is of low strength, hardness and rigidity, but has a high ductility and impact strength as well as low friction. It shows strong creep under persistent force, which can be reduced by addition of short fibres. It feels waxy when touched.

Heavy Duty bags are designed for long distance shipping, as a part of industrial packaging sector, used to transport bulky materials or great amounts of materials from one place to another. Heavy duty plastic bags are constructed using strong polyethylene films which are designed to serve as holding for fertilizers, sand, garden compost, mulch, wood pellets, potting soil, seeds, sand, decorative rocks, and other heavy industrial products. These are strong films distinguished from those of normal PE bags such as shopping bags. According to the material and the weight they are about to hold, film thickness differs in accordance with the weight.
