OXYGEN SCAVENGING FILM WITH GOOD INTERPLY ADHESION

摘要

An oxygen scavenger film includes a layer including a blend of an oxygen scavenger and a polymer selected from high density polyethylene, polypropylene or a propylene copolymer, and a sealant layer. Alternatively, both the oxygen scavenging layer and the sealant layer include a polymer selected from high density polyethylene, polypropylene or a propylene copolymer. The hot tack strength of these films is at least 2.0 Newtons/inch at 135°C, according to ASTM F 1921-98, measured with DTC instrumentation.
