Abstract
An apparatus and process for recycling scrap film. The apparatus includes a washer-shredder upstream from a film cutter in order to remove impurities from the film. The scrap film is rinsed in a rinse loop which uses screen sieves for removing additional impurities, particularly paper fiber. The apparatus and method substantially reduce conventional problems with the film cutter caused by impurities which customarily are present in unwashed film. The invention is particularly useful for recycling very thin scrap film.
