Polyolefin compositions and films obtained therefrom

摘要

Polyolefin compositions containing from 70 to 99 parts by weight of a composition (A) that includes (i) from 75 to 95% by weight of a copolymer of ethylene with an alpha-olefin CH2=CHR, where R is an alkyl radical having from 1 to 10 carbon atoms; and (ii) from 5 to 25% by weight of a copolymer of propylene with ethylene and/or an alpha-olefin CH2=CHR1, where R1 is an alkyl radical having from 2 to 10 carbon atoms, and from 1 to 30 parts by weight of a polyolefin component (B) that includes crystalline polybutene-1. The compositions can be used for making films.
