A method for producing a tightly sealed bag packaging and to a tightly sealed bag packaging having at least one perforation and a receiving area surrounded by a plate-shaped edge region for the inert packaging of a product containing active ingredients, wherein the bag packaging comprises cover films or cover film segments bounding the receiving area and forming the edge region. The cover films or cover film segments are each provided with a channel system having at least one channel. The channel system crosses the part of the cover film or the cover film segment covering the receiving area. At one end, each channel is provided with a branching into two channel branches, Furthermore, a slit is arranged between the two channel branches, interrupting a peripheral edge of the bag packaging. |

1. A method for producing a hermetically sealed bag packaging (10) for the inert packaging of a product containing active substances (5) comprising the following steps:
wherein two cover films (41, 61) or cover film portions are connected together in an edge region (11) which defines a receiving region (12), wherein at least one perforation (19) is introduced into the edge region (11), wherein a channel system (56, 76) having at least one channel (45, 65), which crosses part of the cover film (41; 61) or of the cover film portion that covers the receiving region (12), is introduced into the two cover films (41, 61) or cover film portions by means of a laser, wherein each channel (45, 65) merges at one end in a branching (44, 64) into two channel branches (43, 42; 62, 63), and, wherein an incision (23) which interrupts a peripheral edge (24) of the bag packaging (10) is introduced between the two channel branches (42, 43; 62, 63). |
