Abstract
A multilayer film is hermetically heat sealable over a broad temperature range. In one embodiment, a heat sealable layer is provided to a polypropylene core layer. The heat sealable layer comprises an ethylene-propylene copolymer and/or an ethylene-propylene-butene terpolymer with an inorganic antiblock agent having a particle size of at least 0.8 micron and at least about 1000 ppm of a fatty acid amide, the layer having a thickness of at least about 10-25% of the total film thickness. A metal-receiving layer may be provided to a surface of the core layer opposite the heat-sealable layer and the film may be metallized.
