Abstract
A multilayer film in which at least one layer (A) comprises a copolymer (A1) of propylene with hexene-1 containing from 4 to 10% by weight of hexene-1 and having Melt Flow Rate from 1 to 10 g/10 min.; and at least one layer (B) comprises a copolymer (B1) of ethylene containing up to 20 mol % of CH2=CHR α-olefins and having a density from 0.88 to 0.945 g/cm3
Claims6
A multilayer film in which at least one layer (A) comprises a copolymer (A1) of propylene containing from 4 to 10% by weight of hexene-1 and having a Melt Flow Rate (MFR, measured according to ISO 1133, 230° C./2.16 kg) from 1 to 10 g/10 min.;
- and at least one layer (B) comprises a copolymer (B1) of ethylene with at least one CH2=CHR α-olefin, where R is a C1-C10 alkyl radical, the copolymer containing up to 20 mol % of CH2=CHR α-olefins and having a density from 0.88 to 0.945 g/cm3.
A process comprising packaging an article with a multilayer film in which at least one layer (A) comprises a copolymer (A1) of propylene containing from 4 to 10% by weight of hexene-1 and having a Melt Flow Rate (MFR, measured according to ISO 1133, 230° C./2.16 kg) from 1 to 10 g/10 min.;
- and at least one layer (B) comprises a copolymer (B1) of ethylene with at least one CH7=CHR α-olefin, where R is a C1-C10 alkyl radical, the copolymer containing up to 20 mol % of CH2=CHR α-olefins and having a density from 0.88 to 0.945 g/cm3.
