Main source of waste polyethylene film

1 film in the production of defective products. These wastes are clean and the varieties are clear and can be crushed and compressed directly into the extruder granulation, and the recovery process is relatively simple.

2 from the chemical industry, electrical industry, food and consumer goods industry, etc.. These waste film have been contaminated, some of which have been dyed and printed trademark, also contains some impurities, such as sawdust or sand paper.
