Propylene/ethylene copolymer film for heat seal
The present disclosure provides compositions, films and articles containing a random propylene/ethylene copolymer and a substituted phenylene aromatic diester. Polymerization with an improved catalyst system increases the amount of ethylene incorporated into the random propylene/ethylene copolymer backbone which results in improved thermal properties, improved optical properties, and improved heat seal properties.
