ROBUST PLANAR COMPOSITE WITH AN INTERMEDIATE LAYER OF INCREASED VICAT SOFTENING TEMPERATURE.

摘要

The present invention generally relates to a sheetlike composite (3) comprising a layer configuration with the following layers: 0. optionally a layer of thermoplastic KSu (13); 1. a carrier layer (4); ii. a first layer of thermoplastic KSv (35); iii. a barrier layer (5); iv. a second layer of thermoplastic KSa (6); v. at least one further layer of thermoplastic KSw (7); wherein the Vicat softening temperature of the layer of thermoplastic KSv (35) and the Vicat softening temperature of the layer of thermoplastic KSa (6) is in each case higher than the Vicat softening temperature of the layer of thermoplastic KSw (7). The present invention furthermore relates to a process for the production of the sheetlike composite, a container which surrounds an interior and comprises at least one such sheetlike composite, and a process for the production of this container.
