Abstract
The present disclosure is directed to compositions and film structures suitable for heat seal production. The heat sealable flexible film structure includes: a layer (A) comprising a propylene-based plastomer or elastomer ('PBPE') and a low density polyethylene; a layer (B), adjacent to layer (A), comprising at least 50 percent by weight of the layer (B) of an ethylene-based polymer; and an outermost layer (C) comprising a material having a melting point greater than 140° C. Weight percents are based on the total weight of the respective layer. The heat sealable flexible film structure is used to make a flexible container () having one or more heat seals (). The heat seal () can be a frangible heat seal, a hard heat seal, or a combination thereof.
