Can agricultural film be recycled?

Agricultural films mainly include mulch film and shed film. The mulch film is mainly PE film, and the shed mold includes PE, PE/EVA, and PVC films. When recycling and recycling, PE and PVC films should be distinguished. Agricultural films are generally dirty and It often contains soil, sand, grass roots, iron nails, iron wires, etc. Iron impurities should be removed and cleaned. The main method of recycling is to use a film granulator to granulate. After cleaning and drying, the waste film can be directly produced by hot extrusion method to produce plastic products, such as pots, barrels, plastic flanges, etc. The film granulator is used as follows:

1. PE recycled pellets, PE recycled pellets can be used to produce agricultural film, and can also be used to make fertilizer packaging bags, garbage bags, agricultural recycled water pipes, fences, tree supports, pots, barrels, trash cans, geotechnical materials, etc.

2. PVC recycled pellets, PVC recycled pellets can be used to produce heavy packaging bags, agricultural water pipes, shoe soles, etc.

3. Packaging film: The materials of packaging film include cellophane (cellophane), PE, PVC, PP, EVA, PVDC, PA, PET and various composite films. The single-layer packaging film of one material can be directly made into plastic products like agricultural films after sorting and cleaning, or can be made into various products after granulation. Composite films include composite films of different plastics and films made of plastic and paper, aluminum foil, and other materials. The recycling process after recycling is more complicated. Multi-layer plastic composite films include PE/PP, PE/EVA/PE, PE/adhesive/PA/adhesive/PE, PP/PVDC, etc. Before recycling, different materials must be separated first.

4. Paper-plastic composite film: paper-plastic composite film needs to be separated before recycling.
