A composition of matter particularly well suited for use as a peelable seal layer is described. The composition comprises from about 50 to about 85 percent by weight of a first polymer and from 15 to 50 percent of a second polymer. The first polymer is a propylene based polymer characterized by having a melting point of at least 125� C. together with a Comonomer Composition Distribution Breadth ("CCDB") less than 2. The second polymer is characterized by having an interfacial adhesion with the first polymer of less than 1 lb/inch.
