Abstract: A multilayer film for manufacturing a pouch, includes: a core layer, and an outer layer, wherein: the outer layer and the core layer are made integral with a tie layer, the core layer includes an ethylene vinyl alcohol copolymer having an ethylene content ranging from 25 to 48 mol %, alone or in mixture with an ionomer acid ethylene copolymer, the outer layer includes a polyolefin having a density ranging from 0.910 g/cm3 to 0.940 g/cm3 or a copolymer of ethylene and ?-olefin having a density ranging from 0.870 g/cm3 to 0.910 g/cm3, or a mixture thereof, the tie layer includes a copolymer of polyolefin grafted with a carboxylic acid or an anhydride of carboxylic acid, alone or in mixture with (H) a copolymer of polyolefin. The process for manufacturing such a film, and the single-use pouch manufactured from that film are also described.

Abstract: A film for manufacturing a pouch includes a contact layer including (A) a copolymer of ethylene and ?-olefin having a density in the range of 0.870 g/cm3 to 0.910 g/cm3, alone or in mixture with (B) a polyolefin having a density in the range of 0.910 g/cm3 to 0.940 g/cm3, the contact layer including less than 0.10 wt %, preferably less than 0.07 wt %, of additives able to release a degradation compound further to gamma irradiation in the range of 25 kGy-50 kGy that can slow down or delay cellular growth. The process for manufacturing such a film, as well as the single-use pouch manufactured from that film are also described.
