Title
(EN) ORIENTED HDPE LAMINATES FOR EASY DIRECTIONAL OPENING
(FR) STRATIFIES ORIENTES D'HDPE DONNANT UNE OUVERTURE DIRECTIONNELLE FACILE
Abstract
(EN)
This invention provides oriented plastics film packaging which has easy directional control of opening and is reclosable. One aspect of the invention is a laminate which comprises: (i) a film of high density polyethylene laminated to (ii) an oriented web wherein (i) is biaxially oriented such that the ratio of the deformation ratio in the transverse direction to the deformation ratio in the machine direction is greater than 1.
(FR)
L'invention concerne un emballage à couches plastiques orientées qui procure une bonne maîtrise directionnelle d'ouverture et peut se refermer. Un aspect de l'invention concerne un stratifié comprenant: (i) une couche d'un polyéthylène à haute densité (HPDE) laiminée sur (ii) une bande orientée. Cette couche présente une orientation biaxiale telle que le rapport entre le rapport de déformation transversale et celui de la déformation intervenant dans le sens de la machine dépasse 1.
