Zusammenfassung: | A partially metallized packaging film and method of making is disclosed. In one aspect, at least one portion of a vaporized metal stream is shielded from contacting a sheet of packaging film during the metallization process. The shield is a rigid plate and can be shaped to provide a sharp transition from transparent film to opaque film, or it can provide a gradual transition from transparent film to opaque film. The partially metallized packaging film can be used with a form, fill and seal machine or other packaging machine to create a food package with a product viewing window. In one aspect, the barrier web comprises a bio-based film. |
