Abstract
A durable, high strength, lightweight film laminate of two layers of three-ply film with a nonwoven filament for reinforcement and permanently flexible adhesive between the film layers. The nonwoven filament is in a reinforced laminate and is an excellent protective covering and packaging material because of its resistance to weather elements, tears and punctures.
