| abstract |
The present invention is related to a multilayer structure, comprising a barrier layer adhesively sandwiched between a first polymer layer and a second polymer layer, wherein: - the barrier layer is selected from the group consisting of aluminum foil, a metal oxide layer, and metallized polymer layer, vinylidene chloride (co)polymers, ethylene-vinyl alcohol copolymers, vinylidene chloride (co)polymer-coated films, ethylene-vinyl alcohol copolymer-coated films, hybrid systems comprising a mixture of vinyl alcohol comprising (co)polymer(s) and metal oxide(s), hybrid systems comprising a mixture of vinyl alcohol comprising (co)polymer(s) and inorganic layered mineral(s) and combinations thereof; - the first polymer layer is selected from the group consisting of polyester polyamide and polyolefin; - the second polymer layer is selected from the group consisting of polyolefin, polyacrylonitrile, acrylonitrile/methylacrylate copolymer, cyclic olefin (co)polymer, ionomer and combinations thereof; wherein at least the adhesive layer between the barrier layer and the second layer comprises crosslinked (meth)acrylic copolymers. The present invention also relates to packaging, produced from said multilayer films, for alkaline filling goods. |
