Title
(EN) ENVIRONMENTALLY-FRIENDLY MULTI-LAYER FLEXIBLE FILM HAVING BARRIER PROPERTIES
(FR) FILM SOUPLE À COUCHES MULTIPLES RESPECTUEUX DE L'ENVIRONNEMENT DOTÉ DE PROPRIÉTÉS DE BARRIÈRE
Abstract
(EN)
A multi-layer film with barrier properties having one or more layers made from a bio-based film is disclosed. In one aspect, the print web comprises a bio-based film. The bio-based film can comprises polylactide or polyhydroxy-alkanoate. Unlike prior art petroleum-based films, the bio-based film of the present invention is made from a renewable resource and is biodegradable.
(FR)
La présente invention concerne un film à couches multiples doté de propriétés de barrière comportant une ou plusieurs couches fabriquées à partir d'un film d'origine biologique. Dans un aspect de l'invention, la bande d'impression comporte un film d'origine biologique. Le film d'origine biologique peut comporter du polylactide ou du polyhydroxyalcanoate. Contrairement aux films à base de pétrole de l'art antérieur, le film d'origine biologique de la présente invention est fabriqué à partir d'une ressource renouvelable et il est biodégradable.
