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 hermetically sealed bag packaging (10) comprising:
at least one perforation (19) and having a receiving region (12) which is surrounded by a plate-shaped edge region (11) in inert packaging arrangement with a product (5) containing active substances, the receiving region (12) is rectangular and has an edge (25), the receiving region (12) includes a strip (13) which surrounds the product (5) containing active substances, two cover films (41, 61) or a single cover film having two folded cover film portions which define the receiving region (12) and form the plate-shaped edge region (11), the two cover films (41, 61) or the cover film portions comprise in each case a channel system (56, 76) having at least one channel (45; 65), the channel system (56; 76) crosses the part of each of the two cover films (41; 61) or the cover film portion that covers the receiving region (12), the at least one channel (45, 65) extending in the direction of the product (5) containing the active substances parallel with and offset to the edge (25) of the rectangular receiving region (12), each of the at least one channel (45, 65) comprises a branching (44, 64) into two channel branches (42, 43; 62, 63) on one end thereof and an end point (51) on or proximate a peripheral edge (26) at the other end thereof, the at least one channel (45, 65) between the end point (51) and the branching (44, 64) is a monotone curve with the curve covering a sector angle between 85 to 90 degrees and an incision (23) for interrupting a peripheral edge (24) of the bag packaging (10) is operatively arranged between two channel branches (42, 43; 62, 63) in the plate-shaped edge region (11), each of the channel branches (42,43; 62,63) are on the side of the incision (23), the channel branches (42,43; 62,63) are in symmetrical arrangement with respect to the incision (23), the channel branches (42, 43; 62, 63) are at a predetermined spacing from the peripheral edge (24) of the bag packaging (10) proximate the incision (23). |
