摘要 |
A multi-layer film with barrier properties having two 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. |
