<p>A press-through film (2) for press-through packaging (1) consists of a plastic mixture of those plastics which form at least two phases, that is to say inhomogeneities, in the melt and the film formed therefrom, such that the tearing and tensile strength is reduced. Correspondingly, a packaged product can readily be pressed through this film, but can previously be closed off completely. <IMAGE></p> |
