Abstract

See full text

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 barrier layer, and c) a polymeric internal layer, where a graph of a differential scanning calorimetry of the polymeric internal layer includes a peak A at a temperature TA and a peak B at a temperature TB, where the temperature TB is more than the temperature TA, 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.
