Abstract
Lidding film, without metal foil, for lidding push-through forms of packaging, where the lidding film contains at least one polyolefin-based or polyester-based thermoplastic and the thermoplastic contains 5 to 50 wt % filler material. With the aid of a sealing layer the lidding film can, if desired, be sealed onto the bottom part of a push-through form of packaging or blister pack. The lidding film is inelastic to such a degree that the packaged contents can be pushed through the film.
