A film composite for film packaging, having a cover film composed of a polyolefin and a barrier layer, wherein the cover film has an imprinting, at least in part, on a side that faces the barrier layer. An equalization layer is arranged between the cover film and the barrier layer, which layer borders, at least in part, on the imprinting, wherein the equalization layer is formed from a hardened material on the basis of polyurethane.

A blister package is provided that includes a base made from cyclic olefin copolymer (COC) and a lidding film that includes polyolefin layer(s) or a combination of polyolefin and COC layers, that allows both the lidding film and base to be recycled in a single plastic waste stream.

A heat sealable bag may have overlapping layers of a multi-layer film. The inner adjacent layers of the multi-layer film may comprise a sealant layer that allows an open edge of the bag to be heat sealed by temperatures lower than 255 F for a 6-second dwell time, thereby providing safer operation and potentially allowing thinner plastics to be used, with reduced risk of burn-through. The sealant may include a polyolefin plastomer such as an ethylene alpha-olefin resin.
