Abstract

The invention pertains to a sheet-like composite (100), comprising:a. a carrier layer (103),b. a barrier layer (105),c. an inner polymer layer F (108), andd. an inner polymer layer H (109);wherein the barrier layer (105) comprises- a barrier material layer (106), and- a barrier substrate layer (107) comprising a polyolefin;characterised in that the inner polymer layer F (108) comprises at least 40 wt.-% of a mPE, based in each case on the total weight of the inner polymer layer F (108). 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), to a container precursor (400), a closed container (500), and uses of the sheet-like composite (100), of a mPE, of a LDPE and of a combination of a mPE and a LDPE.
