SHEET-LIKE COMPOSITE, ESPECIALLY PACKAGING LAMINATE FOR DIMENSIONALLY STABLE FOODSTUFF CONTAINERS, HAVING A POLYMERIC INTERMEDIATE LAYER CHARACTERIZED BY DIFFERENTIAL SCANNING CALORIMETRY

摘要

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 T_A and a peak B at a temperature T_B, where the temperature TB is more than the temperature T_A, 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.
