摘要：
The invention pertains to a sheet-like composite, comprising:
a. a carrier layer,
b. a barrier layer comprising a plurality of fibres, and
c. a first inner polymer layer;
wherein a partial sheet-like composite is characterised by a ratio of a first composite tensile strength in a first composite direction to and a further composite tensile strength in a further composite direction in a range from more than 0.5 to 1.9. The invention further pertains to a sheet-like composite with a barrier layer, which is characterised by a ratio of a first tensile strength to a further tensile strength, to methods for producing a sheet-like composite, to the sheet-like composites obtainable by these methods, to rolls and blanks, to container precursors, closed containers, a method which includes obtaining a longitudinal seam, a method for producing a closed container, and uses of a sheet-like composite, a container precursor, a roll or a barrier film.
