  • Patent number: 4643861
    Abstract: Disclosed herein is a process for treating scrap thermoplastic film which has been treated with a saran coating. When the scrap film is cut into a convenient size, it is densified in the presence of a treatment medium which comprises a mixture of lime and an alkyl carboxylate and molded into pellet form. These pellets may then be employed in conventional extrusion and molding equipment without any degradation of the equipment which was normally seen when untreated saran-coated, scrap films were attempted to be molded or extruded.
