Abstract

Multilayer polymeric structures, particularly heat-shrinkable structures, wherein the polymers of which the layers tat are formed are chosen from the following calsses: Class A: a sealing and humidity-protection layer essentially consisting of ethylene copolymers and ethylene/alpha-olefin copolymers and blends thereof; Class B: a tie layer essentially consisting of maleic anhydride grafted polyethylenes; and, in any order; Class C: barrier layers essentially consisting of ethylene vinyl alcohol copolymers (EVOH), or EVOH containing up to 30% of a polyamide; or Class D: polyamides, such that when Class C and Class D polymers are found on adjacent layers, they cannot be the same.
