Abstract
Przedmiotem zgłoszenia jest wielowarstwowa folia opakowaniowa, w szczególności do elastycznego opakowywania produktów wilgotnych, składająca się z szeregu warstw ułożonych w stos, przy czym warstwa rdzeniowa (5) stanowi warstwę środkową i jest wykonana z kopolimeru etylen/alkohol winylowy EVOH, a do warstwy barierowej (5) od strony wewnętrznej przyłączona jest warstwa barierowa (6) wykonana z mieszaniny polimerów, w której 80% wag. stanowi alifatyczny kopoliamid PA6/66 i 20% wag. stanowi aromatyczny poliamid PA6I/6T, następnie poprzez warstwę adhezyjną (7) z żywicy poliolefinowej, pierwsza warstwa wewnętrzna (8) z heksenowego polietylenu liniowego o małej gęstości C6-LLDPE, natomiast od strony zewnętrznej przyłączone są warstwa barierowa (4) wykonana z mieszaniny polimerów, w której 80% wag. stanowi alifatyczny kopoliamid PA6/66 i 20% wag. stanowi aromatyczny poliamid PA6I/6T, następnie poprzez warstwę adhezyjną (3) z żywicy poliolefinowej, pierwsza warstwa zewnętrzna (2) wykonana z mieszaniny polimerów, w której 90% wag. stanowi oktenowy polietylen liniowy o małej gęstości C8-LLDPE i 10% wag. stanowi kopolimer etylenu i octanu winylu. Przedmiotem zgłoszenia jest również sposób wytwarzania wielowarstwowej folii opakowaniowej w procesie współwytłaczania.The subject of the application is a multilayer packaging film, in particular for flexible packaging of moist products, consisting of a number of stacked layers, the core layer (5) being the middle layer and made of ethylene / vinyl alcohol EVOH copolymer, and for the barrier layer ( 5) from the inside, a barrier layer (6) is made of a polymer mixture in which 80 wt. is an aliphatic copolyamide PA6 / 66 and 20 wt. is an aromatic polyamide PA6I / 6T, then through the adhesive layer (7) of polyolefin resin, the first inner layer (8) of low density C6-LLDPE hexene linear polyethylene, while from the outside a barrier layer (4) made of a mixture of polymers is attached in which 80 wt. is an aliphatic copolyamide PA6 / 66 and 20 wt. is an aromatic polyamide PA6I / 6T, then through the adhesive layer (3) of polyolefin resin, the first outer layer (2) made of a polymer mixture in which 90 wt. is octene linear polyethylene with low density C8-LLDPE and 10 wt. is a copolymer of ethylene and vinyl acetate. The subject of the application is also a method for producing multilayer packaging film in the co-extrusion process.
