Patent number: 8329309Abstract: A paper-based lidding material includes a paper layer and a layer containing a cyclic olefin copolymer. The material is useful for blister packaging and particularly suitable for push-through pharmaceutical and food blister packaging. In one embodiment, the lidding material is formed by extrusion coating and includes at least one paper layer, at least one primer layer, at least one tie layer, at least one barrier layer containing one or more cyclic olefin copolymers, and at least one sealant layer in that order. In another embodiment, the paper-based lidding material includes a paper layer laminated to one or more barrier layers containing one or more cyclic olefin copolymers adjacent to one or more sealant layers. Embodiments of the invention can be sealed to a variety of blister films, including films that are chloride-free, to provide environmentally benign blister packages having good moisture properties.Type: GrantFiled: March 16, 2009Date of Patent: December 11, 2012Assignee: Winpak Heat Seal Packaging, Inc.Inventors: Ludovic Leplatois, Hojjat Nasseri
