Patent number: 6911244Abstract: The present invention relates to a film structure and a method of manufacturing the same. More specifically, the film structure may include a barrier material made from EVOH, nylon or other thermally sensitive barrier material encapsulated by a first adhesive material. The barrier material and the first adhesive material form a barrier layer and a first set of adhesive layers when coextruded. The barrier layer and the first set of adhesive layers may be coextruded at the same or a similar temperature to form a first extrudate. The extrudate may be encapsulated by or otherwise coextruded with a second adhesive material to form a second extrudate at a higher temperature than the first extrudate that then may be formed into a flat sheet via a die. The first set of adhesive layers protects the barrier layer from high temperatures and long residence times related to the coextrusion/lamination process that may degrade the barrier layer.Type: GrantFiled: December 20, 2002Date of Patent: June 28, 2005Assignee: Pechiney Emballage Flexible EuropeInventors: Robert J.
