Abstract
A composition for sealants and films comprising polymers (A-b), (B-b) and from 0 to 50% by weight (C-b) is taught. Polymer (A-b) contains 10 to 70% by weight of an ethylene/α-olefin polymer having a α-olefin content of 7 to 30 mol %, a density of 0.850 to 0.900 g/cmand a melt flow rate (MFR-A), at 190° C., of 0.1 to 10 g/10 min. Polymer (B-b) contains 10 to 80 wt % propylene polymer with a melt flow rate (MFR-B), at 230° C., of 0.5 to 100 g/10 min. Polymer (C-b) contains an ethylene polymer having a density of 0.900 to 0.960 g/cm. The ratio of MFR-B to MFR-A is 3 to 500.
