Title
(EN) MULTILAYER STRUCTURES WITH ENHANCED ADHESIVE BONDING FORCE AND ARTICLES COMPRISING SAME
(FR) STRUCTURES MULTICOUCHES PRÉSENTANT UNE FORCE DE LIAISON ADHÉSIVE AMÉLIORÉE ET ARTICLES LES COMPRENANT
Abstract
(EN) Provided are multilayer structures and articles comprising same. The multilayer structure comprises: a biaxially-oriented polyethylene film comprising a skin layer with a matte surface and a core, the core comprising one or more core layers; a sealant film; and an adhesive adhering the sealant film to the matte surface of the skin layer of the biaxially-oriented polyethylene film. The multilayer structure can exhibit an enhanced adhesive bonding force in comparison to other multilayer structures.
(FR) L'invention concerne des structures multicouches et des articles les comprenant. La structure multicouche comprend : un film de polyéthylène à orientation biaxiale comprenant une couche de peau présentant une surface mate et une partie centrale, le noyau comprenant une ou plusieurs couches centrales; un film d'étanchéité; et un adhésif collant le film d'étanchéité à la surface mate de la couche de peau du film de polyéthylène à orientation biaxiale. La structure multicouche peut présenter une force de liaison adhésive améliorée, par comparaison à d'autres structures multicouches.
