Abstract (en)

[origin: WO2011147908A1] The invention relates to a method for producing a composite film (15; 15a; 15b; 15c) for a tubular bag (1), wherein the composite film (15; 15a; 15b; 15c) consists of a plurality of layers (16; 16a; 16b, 17, 18; 18a, 23, 24; 24a, 25; 25a; 26, 27; 29) that are interconnected, wherein at least one of the layers (16; 16a; 16b, 17, 18; 18a, 23, 24; 24a, 25; 25a; 26, 27; 29) is designed as a barrier layer (16; 16a; 16b, 17, 18; 18a; 27; 29), and wherein at least one further layer (23, 24; 24a, 25; 25a, 26; 29) is provided that has a recess (30; 30a). According to the invention, the composite film (15; 15a; 15b; 15c) is produced by connecting a first layer structure (19) to a second layer structure (22; 22a), the second layer structure (22; 22a) comprises the at least one further layer (23, 24; 24a, 25; 25a, 26; 29), and the recess (30; 30a) in the at least one further layer (23, 24; 24a, 25; 25a, 26; 29) is produced prior to the connection to the second layer structure (22; 22a) in the second layer structure (22; 22a).
