Sheet-like composite, especially for rigid container, with part of the area of applied external thermoplastic sealing layer

The invention relates to a sheet-like composite comprising a first composite region and a second bonding area; wherein the first composite field includes as mutually superposed layers of an outer surface of the first bonding region to an inner surface of the first composite region: a) a thermoplastic layer A, b) a support layer, c) a barrier layer, and d) a polymer inner layer; wherein the outer surface of the first composite region is a surface of the thermoplastic layer A; wherein the second area includes composite as mutually superposed layers of an outer surface of the second bonding region to an inner surface of the second bonding region: A) a first thermoplastic layer B, B) the carrier layer; C) the barrier layer; and D) the polymer inner layer; wherein the outer surface of the second bonding region is a surface of the first thermoplastic layer B; wherein said second composite portion does not include a portion of the thermoplastic layer A; wherein a layer thickness of the thermoplastic layer A in the first bonding area is more than a thickness of the first thermoplastic layer B in the second bonding area. Furthermore, the invention relates to a method for printing on a sheet-like composite; a container precursor; closed container; a device for printing; and a use of a polyvinyl acetal.
