Abstract
Provided are multilayer polymer films comprising LLDPE, LDPE and a random propylene-ethylene copolymer which films suitable for packaging applications and are mechanically recyclable, and to recycled polymer compositions formed by mechanically recycling such films. The recycled polymer compositions may be combined with a polypropylene random copolymer and used to form further polymer films suitable for packaging applications applications.
