Beschreibung
Zusammenfassung:	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. In one aspect, the barrier web comprises a bio-based film. In 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. Film à couches multiples présentant des propriétés de barrière comportant une ou plusieurs couches faites d'un film d'origine biologique. Selon un aspect de l'invention, la bande d'impression comporte un film d'origine biologique. Selon un autre aspect, la bande de barrière comporte un film d'origine biologique. Selon encore un aspect, un adhésif dorigine biologique fait adhérer la bande d'impression à une bande de barrière. Le film d'origine biologique peut comporter du papier, une PCR, du polylactide ou du polyhydroxyalcanoate. Contrairement aux films à base de pétrole de l'antériorité, le film d'origine biologique de la présente invention est fabriqué à partir d'une ressource renouvelable et est biodégradable.
