Abstract

Entangled and chopped oriented and unoriented scrap plastics film are mixed in a zone 34 with virgin resin transferred from a container 35, the mixture then being transferred to a plasticizing zone 10 to which virgin resin is also transferred to a point downstream from where the mixture enters. <IMAGE>
