Abstract
PURPOSE: An isotactic polypropylene is incorporated with a specific propylene-1- butene random copolymer to produce title composition for package films with improved blocking resistance and mechanical strength without any adverse effect on characteristics of the copolymer.
CONSTITUTION: To 95-50 wt% of a propylene-1-butene random copolymer that has a melt index of preferably 0.1-40, a propylene content of 55-85, preferably 60-82 mol%, and the heat of crystal fusion measured by differentially scanning calorimeter of 10-80, preferably 20-70 Joule/g is melt blended 5-50 wt% of an isotactic polypropylene.
USE: Films for shrink wrapping, protecting films, films for wrapping fibers and general commodities and laminates with other films
