Abstract:
A system for processing a supply of post consumer scrap linear low density or low density polyethylene film into near-virgin quality blown film product. The system includes tearing the supply of film in a shredder, wherein the surface area of the film is exposed, including delaminating the film. The torn supply of film is washed in a water bath including a surfactant. The film is agitated in the bath containing the surfactant wherein contaminants on the film are removed from the film. The washed film is ground into smaller pieces and additional washing of the ground film in a rotating friction washer occurs wherein additional contaminants are removed from the film. The ground film is then dried in a dryer and compacted in a compactor without addition of water into granulated objects of near-virgin quality blown film product.
