发明名称 Laminating film without a release layer, process for the production thereof and use thereof
摘要 The present invention relates to a film of at least two layers having at least one side softening at a lower temperature and at least one side softening at a higher temperature, wherein the higher-softening side substantially consists of a thermoplastic polyurethane which softens at above 100 DEG C. on a Kofler hot bench and the median of the softening range is at least 15 DEG C. above that of the lower-softening layer and the matrix component of the lower-softening side consists of at least one hot-bonding thermoplastic material from the group comprising polyamides, polyesters and polyurethanes having a median of the softening range on a Kofler hot bench of below 100 DEG C. and at least one additive component from the group comprising a) additive masterbatches containing inorganic particles, b) additive masterbatches containing organic particles with thermoplastic matrix resins is added to the lower-softening layer.
