Abstract

The invention pertains to a sheet-like composite (100), comprising a layer sequence which comprises:a. a carrier layer (103),b. a barrier layer (105), andc. an inner polymer layer H (108);wherein the barrier layer (105) comprises a sublayer sequence which comprises- a barrier material layer (106), and- a barrier substrate layer (107);wherein an inner side of the barrier layer (105) faces towards the inner polymer layer H (108); wherein a partial sheet-like composite (109) consists of only the layers of the sheet-like composite (100) which are superimposed to the barrier layer (105) on its inner side; wherein a basis weight of the partial sheet-like (109) composite is less than 33 g/m². The invention further pertains to methods (300, 600, 700) for producing a sheet-like composite (100), a container precursor (400), and a closed container (500), respectively; to a container precursor (400); to a closed container (500); and to a use of the sheet-like composite (100).
