Abstract

A material suitable for sealing plastic containers and used as a lid on a container for food is disclosed. The material comprises a substrate joined to a film comprising a mixture of a butene-1 polymer, polypropylene, an organic filler, and, optionally, high density polyethylene. The material is heat sealable, peelable and retains high burst strength both during and after retorting at elevated temperatures.
