摘要: Co-extruded multilayer packaging films suitable for packaging fluid products, showing a very good balance of mechanical, chemical and, optionally, barrier properties, good sealability, heat resistance and unexpectedly improved optical properties, a process for their manufacturing, pouches and packages obtained from them, are disclosed. These films comprise a core layer (D) comprising a polyamide; two tie layers (C), directly adhered to the opposite surfaces of the core layer; at least one intermediate layer (B), directly adhered to the opposite surface of a tie layer (C), comprising high density polyethylene; and two outer layers (A) comprising an ethylene/alpha olefin copolymer.
