Sheet-like composite with polymeric intermediate layer characterized by differential scanning calorimetry, in particular packaging laminate for dimensionally stable food container

摘要

The present invention provides a sheet-like composite material comprising, in the direction from the outside of a sheet-like composite material to the inside of a sheet-like composite material, a layer comprising a) a carrier layer, b) a polymer intermediate layer, And c) a barrier layer, wherein the graph of the differential scanning calorimetry of the polymeric intermediate layer shows a temperature T_APeak A and temperature T_BAnd peak B at temperature T_BIs the temperature T_AAnd the width of the peak B is at least 3 C. narrower than the width of the peak A. The invention further relates to container precursors and sealed containers comprising sheet-like composites and also to the use of processes and sheet-like composites capable of obtaining sheet-like composites.(FIG.
