摘要
1. Flexible thermoplastic structures with multiple coextruded polymeric layers comprising a vinylidene chloride copolymer layer bonded to a plasticized vinyl chloride polymer layer, characterized in that the vinylidene chloride copolymer layer is bonded to the plasticized vinyl chloride polymer layer through the intermediacy of a mixture of polymeric adhesives consisting of 10 to 90 parts by weight of a copolymer of vinyl acetate and ethylene and of 90 to 10 parts by weight of a copolymer of vinyl chloride and vinyl acetate and whose shear elastic modulus G' at 121 degrees C and 10**-4 cycles/second is greater than 0.5 10**3 Pa.
