Abstract: The invention relates to a sheetlike composite comprising, as mutually superposed layers in a direction from an outer face of the sheetlike composite to an inner face of the sheetlike composite, a) a carrier layer, b) a first adhesion promoter layer having a first acrylate content, c) a barrier layer, d) a further adhesion promoter layer having a further acrylate content, and e) an inner polymer layer; wherein the first acrylate content and the further acrylate content are each in a range from 7% to 40% by weight, based on the weight of the respective adhesion promoter layer.

Abstract: The present invention relates generally to a planar composite including, as a layer sequence, a first PE blend layer, a carrier layer, a barrier layer, and a further PE blend layer. The first PE blend layer or the further PE blend layer in each case includes in a range of from 10 to 50 wt. %, in each case based on the blend, a first LDPEa, and a further LDPEt to the extent of at least 50 wt. %, in each case based on the blend. The present invention furthermore relates to a process for the production of the planar composite, a container which surrounds an interior and comprises at least one such planar composite, and a process for the production of the container including the steps of provision of the planar composite of the abovementioned layer construction, folding, joining and optionally filling and closing of the container.

Abstract: Shown and described herein is a procedure for manufacturing a composite material with temperature-resistant bonding agent and a composite material manufactured according to this procedure, in particular for sterilizable, pasteurizable or autoclavable packaging, with at least one barrier layer, wherein at least one bonding agent layer is provided to increase adhesion between the barrier layer and a plastic or cardboard layer. To entirely omit the heat post-treatment of the composite material, it is provided that the layer to be coated be heat treated before applying the bonding agent layer. The dimensions of the coating systems and associated investments are reduced as a result.
