Abstract

A peelable and heat sealable lidstock material comprises a metal or polymer substrate laminated with a film comprising a mixture of a butene-1 and ethylene copolymer, an ethylene homopolymer or copolymer, an inorganic filler and optionally, a propylene homopolymer or copolymer. The filler makes up at least about 18 wt.% of the mixture and is preferably talc having an average particle size of about 1-2 microns and a carboxylic acid surface coating.
