What are the plastic bags made of?
General civilian products, mostly polyethylene (PE) to do, PE is divided into low pressure high-density HDPE, low pressure high-density LDPE and linear low-density LLDPE
Barrels are usually produced in HDPE, and as for plastic bags, these materials can be made, including polypropylene. Relatively soft is made of high pressure material, relatively hard bag is made of low pressure material, hard and quite, is PP do. Linear low density polyethylene has a strong tear resistance and is generally improved by adding a certain percentage to high pressure polyethylene. The requirements are not too high to add some recycled materials and should be appropriate to reduce the cost of filling masterbatch.
