Patent ID: 8822020

Claim:
A calenderable molding composition comprising (i) vinyl chloride polyrner or polyvinyl chloride in an amount of from 5 to 94% by weight, said vinyl chloride polymer or polyvinyl chloride having a K value of from 50 to 90, (ii) additives making up from 2 to 25% by weight, and (iii) a polymer comprising semicrystalline or amorphous polyester whose crystallization half-life time in the molten state is at least equal to or greater than 5 minutes, wherein the molding composition is a blend of vinyl chloride polymer or polyvinyl chloride and of the polyester as modifier for orientability, the proportion of the polyester is from 5 to 90% by weight of the molding composition, and the foregoing percentages by weight are based on the total weight of the molding composition, a film formed from said molding composition is oriented using a transverse stretching ratio of from 3 to 7, a calendared film formed from said molding; composition exhibits a transverse shrinkage of from 45 to 80% at a temperature of 95° C. and a film having a thickness of 50 microns formed from said molding composition exhibits a haze ranging from 2 to 5%.
