FILM LAMINATE FOR A TEAR-OPEN PACKAGE |
摘要 |
A laminate for a tear-open package has an inner heat-sealable polymer film and an outer laser-cuttable polymer film laminated thereto, respectively forming a cover layer and a seal layer. The outer film is formed with at least one linearly extending laser score groove or scoring extending transversely at least partially through a thickness of the outer film. The inner film is formed along and in alignment with the laser scoring with a perforation line comprised of a row of cuts spaced along the scoring and separated by webs extending across the scoring. The cuts extend transversely at least partially though a thickness of the inner film. |
