How about boPP adhesive tape scrap?
The membrane recycled granules are used as follows1, PE PE of recycled aggregate, the recycled aggregate can be used for production of plastic sheeting, can also be used to make fertilizer bags, garbage bags, agricultural reclaimed water, fences, trees, pots, barrels, trash, geotechnical materials etc..2, PVC PVC of recycled aggregate, the recycled aggregate can be used to produce heavy bags, agricultural water pipe, such as sole, packaging film, packaging film materials including glass paper (cellophane), PE, PVC, PP, EVA, PVDC, PA, pet and all kinds of composite films. A packing film of a single material, which can be directly made into plastic products or made into various products after being sorted and cleaned. Composite films include composite films made of different plastics, and films made of plastic and paper, aluminum foil and other materials. The recycling process after recovery is more complicated, such as:Multilayer plastic composite film, multilayer plastic composite film has pe/pp, pe/eva/pe, pe/ adhesives, /pa/ adhesives, /pe, pp/pvdc, etc., before recycling, first of all, different materials should be separated. Separation by solvent separation.
1, the film recyclingThe film is a natural, plastic products in variety, service life is short, recovery is one of the main varieties of recycling, according to use morphological profile examples.(1) agricultural film, agricultural film are mainly plastic film and plastic film films, mainly for PE film, PE pe/eva, has shed film, PVC film, in recycling, should distinguish between PE and PVC film, agricultural film is dirty, and often clip with dirt, sand, grass, nails, wire so, to remove iron impurities and cleaning, recycling method is mainly granulation, if, with manual sorting, cleaning condition, after cleaning, waste film can be dried directly by hot extrusion method for the production of plastic products, such as pots, barrels, plastic flange etc..
Recycling of waste plastic film - China Renewable Resources Trading NetworkTime: 2008-5-29 recycling of waste plastics
Paper plastic composite film, paper plastic composite film on recycling before the first paper separation, this is a method of paper plastic composite separation, separation equipment for electric heating with a chrome plated hollow barrel, the barrel is equipped with a hollow cylinder with a blade, the cylinder and the hollow cylinder to rotate in the opposite direction, a mixture of paper and plastic after the break of the adding barrel in the barrel by heating a mixture of the plastic melt in the barrel at the lower part of the discharge, the air in the hollow cylinder exhaust.Aluminum plastic composite film, aluminum-plastic composite film has bopp/ aluminum, pe/ aluminum, etc., used for a variety of food packaging, after use of aluminum plastic composite flexible packaging bag, in fact, is a mixed waste, recycling is more difficult. The main methods of treatment are incineration and recovery of heat. China has a method of burning aluminum and crushing and adding stuffing to make low grade crude products. The effect is not very satisfactory. An example of the use of aluminum in the manufacture of antistatic functional materials is described:Aluminum plastic composite waste - Cleaning - grinding - Screening - aggregate - aluminum powder - auxiliary - extrusion - Semi-finished - extrusion - finished products
