Abstract
Multi-layer laminated structures are disclosed. Such structures include a multi-layer polymeric film having a Layer A that includes at least one polymer and a polymeric sealant layer adjacent to Layer A. The sealant layer has a surface roughness, Ra>5.0 and a Peak Count Value, Pc>50.0. The multi-layer laminated structures also include a substrate in surface contact with the multi-layer polymeric film, typically opposite the sealant layer. Such structures have a top seal and/or side seal of the polymeric sealant layer to itself has a seal strength of >5.00×102 grams/inch at 177° C. The multi-layer 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.
