Abstract

Multi-layer films particularly suited for packaging applications, including a core layer, a seal layer located on one side of the core layer, the seal layer comprising a polyolefin polymer and a silicone gum and a metallized layer located on the opposite side of the core layer from the seal layer are provided. Optionally, the multi-layer film may have a first tie layer located intermediate the core layer and the seal layer and/or a second tie layer located intermediate the core layer and the metallized layer. Embodiments may have the desirable combination of improved metal adhesion and slip properties.
