    摘要: Gas impermeable thermoplastic films of multilayer construction are disclosed which are particularly suitable for use in the manufacture of inflatable packaging cushions for protection of packaged objects. The multilayer films have outer heat sealable layers which are radio frequency inactive. The inflatable packaging cushion is fabricated by heat sealing the outer layers of the multilayer film together to form gas inflatable pockets using conventional heat sealing techniques. The heat sealed regions have increased mechanical strength without the need for post irradiation treatment. The thermoplastic film includes at least two outer layers of heat sealable material including linear low-density polyethylene polymers separated by a gas impermeable layer, e.g., an oxygen barrier. Additional adhesive layers and/or structural intervening layers may be coextruded in forming the resulting thermoplastic films.
