ABSTRACT:
The present invention concerns a sealed package formed from a polymer film comprising a block copolymeric substrate and a heat sealable coating and/or skin layer on the substrate, the package being formed by wrapping the film around an article to be packaged in a manner to obtain at least one region of film overlap, and heat sealing the resulting overlapped film sections to each other to provide at least one sealed region of the package, the sealed region being subsequently openable by manually separating the overlapped film sections, effective without substantial tearing of the film at or around the sealed region.
