Multi-layer polyolefin film containing recycle polymer from cross-linked films.

摘要

A process for the manufacture of a multilayer cross-linked, heat-shrinkable, polyolefin film, said film having at least one inner layer comprising thermoplastic polymer sandwiched between two outer layers comprised of thermoplastic polymer different from the thermoplastic polymer of said inner layer, comprising the steps of a) coextruding the materials into a tape; b) cross-linking it; c) converting said cross-linked tape into a heat-shrinkable film by orientation; characterized in that scrap material produced in the manufacture or in the further processing to finished articles of cross-linked films of this same structure is incorporated by recycling it into said step a) in an amount up to 50% by weight of the total film weight.
