Flat compound with plastic layers of different softening temperatures of Vicat

摘要

The present invention generally relates to a sheetlike composite (3) comprising a layer configuration with at least the following layers: i. a first layer of thermoplastic KSu (13); ii. a carrier layer (4); iii. a barrier layer (5); iv. a second layer of thermoplastic KSw (7); wherein the sheetlike composite has at least one further layer of thermoplastic KSv (35); wherein the Vicat softening temperature of the layer of thermoplastic KSu (13) is 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 surrounding an interior which comprises at least one such sheetlike composite, and a process for the production of this container.
