Abstract | Recyclable, all-polyethylene laminate film structures suitable for use in a flexible packaging are disclosed. The structures comprise a film layer consisting essentially of an ethylene-based polymer and a barrier adhesive layer disposed on a surface of the film layer, wherein the structure has an oxygen transmission rate not greater than 100 O2/m2/day, measured according to ASTM Method D3985. Recyclable, all-polyethylene laminate film structures suitable for use in a flexible packaging are disclosed comprising (A) a sealant film layer consisting essentially of an ethylene-based polymer, (B) an intermediate film layer consisting essentially of an ethylene-based polymer, (C) a structural film layer consisting essentially of an ethylene-based polymer, and (D) a barrier adhesive layer, wherein the recyclable, all-polyethylene laminate film structure has an oxygen transmission rate not greater than 100 O2/m2/day, measured according to ASTM Method D3985. Articles comprising the disclosed laminate film structures, such as flexible packaging and stand-up pouches, are also disclosed.
L'invention concerne des structures de film stratifié entièrement en polyéthylène recyclable appropriées pour une utilisation dans un emballage souple. Les structures comprennent une couche de film constituée essentiellement d'un polymère à base d'éthylène et d'une couche adhésive barrière disposée sur une surface de la couche de film, la structure ayant un taux de transmission d'oxygène non supérieur à 100 O2/m2/jour, mesuré selon la méthode ASTM D3985. L'invention concerne des structures de film stratifié entièrement en polyéthylène recyclable appropriées pour une utilisation dans un emballage souple comprenant (A) une couche de film d'étanchéité constituée essentiellement d'un polymère à base d'éthylène, (B) d'une couche de film intermédiaire constituée essentiellement d'un polymère à base d'éthylène, (C) d'une couche de film structural constituée essentiellement d'un polymère à base d'éthylène, et (D) d'une couche adhésive barrière, la structure ayant un taux de transmission d'oxygène non supérieur à 100 O2/m2/jour, mesuré selon la méthode ASTM D3985. L'invention concerne également des articles comprenant les structures de film stratifié décrites, tels que des sachets verticaux et d'emballage souples. |
