Abstract:
Heat sealable, multi-layer laminating film composed of at least seven layers consisting of an outer layer (a) on the sealing side, followed towards the laminating side by a layer (b), followed in turn by a coupling layer (c), a layer (d) consisting of at least 50% by weight, based on its total weight, of an ethylene/vinyl alcohol copolymer, a coupling layer (e) and on the laminating side at least one layer (f) wherein layers (a), (b) optionally the coupling layers (c) and (e) and layer(s) (f) contain a thermoplastic polymer or a mixture of thermoplastic polymers and the softening point of layers (b), (f) and optionally (c) and (e) is lower than the softening point of layer (a).
