Abstract (en)
[origin: WO2014141308A1] Heat-shrinking multilayer polymeric film, co-extruded and bi-axially stretched, with barrier effect to gases and to water-vapour, wherein a layer pack responsible for said barrier effect comprises at least one polyamide (PA) layer and at least one ethylene-vinyl alcohol copolymer (EVOH) layer, mutually adjacent, and wherein between said polyamide (PA) and ethylene- vinyl alcohol copolymer (EVOH) layers an intermediate bonding layer consisting of a compensating adhesive polymer is arranged. Said adhesive polymer is an ethylene-based polymer with tackifying additives, or an ethylene-based polymeric adhesive having a modified rheology.
