Abstract:
The disclosure provides a multilayer blown film for stretch hood made from or containing a layer made from or containing a first polyolefin composition made from or containing from 20 wt % to 80 wt %, based upon the total weight of the first polyolefin composition, of Component A) and from 20 wt % to 80 wt %, based upon the total weight of the first polyolefin composition, of Component B); wherein Component A) is an ethylene copolymer and Component B) is a polyolefin composition made from or containing: (i) 5-35% by weight, based upon the total weight of Component B, of a propylene homopolymer or a propylene ethylene copolymer (ii) 20-50% by weight, based upon the total weight of Component B, of a copolymer of ethylene and a C3-C8 alpha-olefin; and (iii) 30-60% by weight, based upon the total weight of Component B, of a copolymer of ethylene and propylene.
