Multilayer film comprises (a) a sealing layer based on at least one heat-sealable, thermoplastic olefin homo and/or copolymers, (b) adhesive layer separable by a cohesive speel, (c) optionally a layer based on at least one homo- and/or copolyamide, (d) a barrier layer, (e) optionally a layer based on at least one homo- and/or copolyamide, (f) optionally a second adhesive layer, (g) optionally a layer based on at least one thermoplastic olefin homo- and/or and copolymers, and (h) a support layer based on at least one thermoplastic polymer. Multilayer film comprises a layer sequence of (a) a sealing layer based on at least one heat-sealable, thermoplastic olefin homo and/or copolymers, (b) adhesive layer separable by a cohesive speel, based on a mixture of at least one modified thermoplastic olefin homo and/or copolymers, that are modified with = 1 wt.% of polar organic groups, as a first polymeric component and up to 50 wt.% of, based on the total weight of the mixture, at least one homo and/or copolymer of a (meth)acrylate as a second polymeric component, where first polymeric component has no (meth)acrylate units, (c) optionally a layer based on at least one homo- and/or copolyamide, (d) a barrier layer, (e) optionally a layer based on at least one homo- and/or copolyamide, (f) optionally a second adhesive layer, (g) optionally a layer based on at least one thermoplastic olefin homo- and/or and copolymers, and (h) a support layer based on at least one thermoplastic polymer. An independent claim is included for an easy-open packaging of a multilayer film that is sealed by sealing the sealing layers to each other by sealing edges. |
