Agricultural film recycling is one of the main varieties of plastic recycling. With the promotion of plastic film covering technology, there has been a problem of waste plastic film left in the fields. Agricultural experts pointed out that where plastic film is used to cover crops, the waste plastic film scattered in the fields should be cleaned up in time. Because the plastic film is made of a polyethylene material, it is not easy to decompose under natural conditions. If it is left in the soil, it will hinder the extension of the root system of crops.
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 film. When recycling, PE and PVC film should be distinguished. Agricultural film is generally dirty. Remove impurities and wash. The main method of recycling is granulation, and the waste film after cleaning and drying can be directly used to produce plastic products by hot extrusion, such as basins, barrels, plastic flanges, etc.
The uses of waste plastic agricultural film recycled pellets are as follows:
(1) PE recycled pellets
PE recycled pellets can be used to produce agricultural film, and can also be used to manufacture fertilizer packaging bags, garbage bags, agricultural recycled water pipes, fences, tree supports, pots, barrels, garbage bins, geotechnical materials, etc.
(2) PVC recycled pellets
PVC recycled pellets can be used to produce heavy packaging bags, agricultural water pipes, shoe soles and other packaging films. The materials of packaging films include various composite films. Single-layer packaging film of one material, after sorting and cleaning, can be directly made into plastic products like agricultural film or made into various products after granulation.
