Claim 10:
11. A multi-layer film comprising
a skin layer,
a core layer comprising a polyethylene material, and
a seal layer comprising a copolyester thermoplastic elastomer material and an ethylene methyl acrylate copolymer and arranged to lie in spaced-apart relation to the skin layer to locate the core layer between the skin layer and the seal layer,
wherein the multi-layer film is configured to bond temporarily to a brim of a container to establish a hermetic seal that survives a pasteurization process and peels away from the brim after the pasteurization process to expose a mouth of the container without leaving any portion of the multi-layer film behind coupled to the brim when a user applies a peel force to the multi-layer film.
