Abstract: The present disclosure provides a film. In an embodiment, a multilayer film having at least three layers is provided. The multilayer film includes two skin layers, each skin layer composed of a blend of a low density polyethylene and an ethylene-based elastomer having a density less than 0.90 g/cc. The multilayer film also includes a core layer located between the skin layers. The core layer includes a propylene-based plastomer having a density less than 0.90 g/cc. The multilayer film has an onset end temperature from 90° C. to 110° C. and a heat seal strength at 120° C. from 1.5 N/cm to 2.5 N/cm.
