Abstract (en)
[origin: WO2022043193A1] The invention relates to a method for connecting at least two substrates (10a, 10b), which each comprise a base material (12) of cellulose, wherein at least one of the substrates (10a, 10b) comprises a layer system (14) applied at least in some regions to the base material (12) and having at least one outer layer (16). The substrates (10a, 10b) are arranged one against the other in such a way that axes of longitudinal extent (A) of the substrates (10a, 10b) are arranged in relation to one another at an angle of between 40° and 140°, after which at least the at least one outer layer (16) of one of the substrates (10a, 10b) is connected in an integrally bonded manner to the other substrate (10a, 10b). The invention also relates to a package comprising substrates (10a, 10b) connected in such a way.
