Multilayer films are disclosed. The multilayer film may include a core layer and a heat seal layer where the heat seal lay comprises a polypropylene copolymer and a polyethylene copolymer. The polypropylene copolymer of the heat seal layer has specific properties such as ethylene content and iCCD elution profile to contribute to the desirable properties of the film. The multilayer film can form effective heat seals, even when in contact with heated contents. The multilayer film can be formed into a bag where the bag is suitable for carrying hot or heated contents.
A multilayer film comprising at least (A) a core layer that comprises a polyolefin polymer and (B) a heat seal layer, wherein the heat seal layer comprises:
