MULTI-LAYER FILMS HAVING IMPROVED SEALING PROPERTIES

摘要

Multi-layer films that are suitable for packaging and having improved sealing properties are disclosed. Some embodiments may also provide a lower minimum sealing temperature. A soft polymer is blended in a core layer and a tie layer comprising the soft polymer and, optionally, another polymer. A sealable layer is provided on the side of the tie layer opposite the core layer. The multi­layer films may be transparent, contain a cavitating agent, or are pigmented to form an opaque film. Also, the multi-layer film may be metallized or coated with, a barrier coating.
