Provided are films made from polymer blends including post-consumer resin (PCR). The films are formed from a polymer blend that includes a PCR, a low density polyethylene and/or ethylene/carbon monoxide copolymer (ECO copolymer), and a modification agent. The films, which include a PCR, contribute to improved sustainability and in aspects maintain or minimize the reduction of desirable properties, such as elastic recovery.
