The invention relates to a sheet-like composite including as layers of a layer sequence, in a direction from an external side of the sheet-like composite to an internal side of the sheet-like composite, a) a carrier layer, b) a polymeric intermediate layer, and c) a barrier layer, where a graph of differential scanning calorimetry of the polymeric intermediate layer includes a peak A at a temperature Tand a peak B at a temperature T, where the temperature TB is more than the temperature T, where a width of the peak B is less by at least 3° C. than a width of the peak A. The invention further relates to a container precursor and to a closed container including the sheet-like composite, and also to a process by which the sheet-like composite is obtainable, and to a use of the sheet-like composite.

Sheet-like composite, especially packaging laminate for dimensionally stable food-stuff containers, having a polymeric internal layer characterized by differential scanning calorimetry

The present invention generally relates to a sheetlike composite () comprising a layer configuration with the following layers: 0. optionally a layer of thermoplastic KSu (); 1. a carrier layer (); ii. a first layer of thermoplastic KSv (); iii. a barrier layer (); iv. a second layer of thermoplastic KSa (); v. at least one further layer of thermoplastic KSw (); wherein the Vicat softening temperature of the layer of thermoplastic KSv () and the Vicat softening temperature of the layer of thermoplastic KSa () is in each case higher than the Vicat softening temperature of the layer of thermoplastic KSw (). 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.

Robust planar composite with an intermediate layer of increased vicat softening temperature

A planar composite for the production of a container surrounding an interior having a. a carrier layer; b. a barrier layer of plastic joined to the carrier layer; c. at least two layers of thermoplastic plastic which are provided on the side of the barrier layer of plastic facing away from the carrier layer. The carrier layer has at least one hole which is covered by the barrier layer of plastic and the at least two layers of thermoplastic plastic. The composite is useful for the production of a container. Also disclosed is a process for the production of a container using the composite and a container obtainable by this process.
