A multi-layer film with harrier 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. In one aspect. the barrier web comprises a bio-based film, hi one aspect, a bio-based adhesive adheres the print web to the barrier web, The bio-based film can include paper, PCR, 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. L'invention porte sur un film multi-couche ayant des propriétés barrière, comportant une ou plusieurs couches faites à partir d'un film d'origine biologique. Dans un aspect, la bande d'impression comprend un film d'origine biologique. Dans un aspect, un adhésif d'origine biologique fait adhérer la bande d'impression à la bande de barrière. Le film d'origine biologique peut comprendre le papier, des fibres recyclées après consommation (PCR), un polylactide ou un polyhydroxyalcanoate. Contrairement aux films à base de pétrole de l'état antérieur de la technique, le film d'origine biologique de la présente invention est fabriqué à partir d'une source renouvelable et est biodégradable.
