Patent abstract
Biaxially oriented polypropylene films (BOPP) having at least one layer of a propylene polymer containing at least 0.8% by weight of ethylene and, optionally, one or more C4-C10 α-olefins, or a propylene polymer composition containing at least 0.8% by weight of one or more comonomers selected from the group consisting of ethylene and C4-C10 α-olefins, and havingI) a melting temperature of 155° C. or higher; andII) a xylene soluble fraction at room temperature lower than 3% by weight, and a value of the ratio of the polymer fraction collected at the temperature range from 25° C. to 95° C. (by TREF) to the said xylene soluble fraction higher than 8.
