Abstract (en)
[origin: US4673601A] A cold- or heat-sealable composite film comprises a permanently adhesive layer which is applied to a carrier film and which, on the side facing away from the carrier film, has a covering layer of a material having a low elongation at break and low tear propagation strengths. If the covering layer is not itself cold- or heat-sealable, it is provided with an appropriate cold- or hot-sealing layer. The composite film can be used as a closing membrane for preformed containers or can itself be formed as a container.
