Abstract

100 pbv. of a thermoplastic resin (mixture) such as a polyolefin, polyvinyl, polyamide, polyester and/or copolymer of similar type, are mixed with 5 to 150 pbv of a solvent whose b.pt. is above flow temp. of the resin(s) but is not >230 degrees C and which is adapted to partly swell the resin but does not dissolve it completely at the deformation temp. of the resin; and 20 to 50 pbv of an inert filler which is stable at deformation temp. Solvent and filler are evenly dispersed in the resin to give a premix which is then shaped e.g. extruded into a foil or sheet which is then biaxially drawn at a temp. between solidification temp. and flow temp. of the resin while the solvent is removed during the shaping and drawing steps. CaCO3, mica, silica etc. are suitable fillers. The paper or leather end product depends on initial web thickness and subsequent draw ratio.
