CA 2091069

Used polyethylene film is shredded and subjected in a solvent bath containing an organic solvent with intense agitation, e.g. by mechanical stirring, to frictional surface cleaning and, at the same time to an extraction process without dissolving plastic. The extraction process releases film additives and PE waxes from the shredded material and removes printing inks, especially through the frictional surface cleaning.
