Abstract

A process for the manufacture of multilayer sheets, characterized by jointly and in combination comprising the following phases: 1) incorporation into a first thermoplastic material normally solid, organic polymer melt extrudable from 500 to 07,000 p.p.m. Of a slip additive based on the weight of said first polymer, 2) incorporation into a second, normally solid, thermoplastic, melt extrudable organic polymer, about 500 to 4,000 p.p.m. Of sliding additive based on the weight of said second polymer, 3) forming said first and second polymer in layers and 4) bringing said layers into register to form a multilayer sheet having a layer of said first polymer and as an adjacent inner layer to the outer layer of said second polymer, such that the concentration of slip additive of the inner layer is greater than the concentration of slip additive of the outer layer.
