Abstract
This product is used for preparing containers, packaging and decorative materials, synthetic paper, etc. It has up to 50% general permeability to light, up to 0.89 compactness, good light-reflecting features, low weight and a specific pearl glossiness. The product contains 100-weight p. of crystal polypropylene and from 3 to 40-weight p. of copolymer of cyclopentadiene compound of aromatic hydrocarbon and/or its hydrated product, with a softening temperature between 160 and 250 degrees C. It is derived by extruding the mixture in a melted condition to an output sheet, which is stretched two or more times in one direction at temperature lower or equal to the softening temperature of the co-polymer or its hydrated product.
