Abstract
Packaging films include a polymeric surface layer made from a blend of polyolefin and thermoplastic rubber, particularly a blend of polyolefin and styrene-isoprene-styrene (SIS) block copolymer or styrene-butadiene-styrene (SBS) block copolymer. The films provide a matte-finish surface without the need for surface treatments. The films can alternatively be surface modified to provide excellent cold seal receptive layers.
