摘要:
The invention relates to a composite film (100) for packaging containers (1), having a film composite made of a plurality of packaging material layers (101 to 108), wherein an inner packaging material layer (108) is designed as a heat-sealing layer and an opening device (10) can be fixed to an outer packaging material layer (101), in particular by sealing to the outer packaging material layer (101), and wherein the packaging material layers (101 to 108) comprise a weakening region (20) in the region of the opening device (10). According to the invention, the weak region (20) is disposed on the side of the inner packaging material layer (108) and is implemented as an at least partial reduction in the layer thickness (D) of the inner packaging material layer (108), wherein the shape of the weak region (20), in particular having a circular cross section, is adapted to the arrangement of cutters (13) that are disposed on a partial circular diameter (T) of the opening device (10) as a part of the opening device (10).

摘要:
A method is presented for fixing an opening device to a packaging container made of a composite film. The packaging container is a tubular bag, and the composite film includes a barrier layer and a further layer. The barrier layer is part of the composite film and the further layer includes a recess in the region of the opening device. The opening device is a connecting flange configured to be fixed to the composite film and includes a separating mechanism configured to sever the barrier layer to form a passage in the composite film. The further layer is arranged on the side facing away from the connecting flange.

A screw closure (2) is provided on a soft packaging (1), preferably a film bag. Said screw closure consists of a first part, which consists of a spout having a fastening flange (4) for connecting to the soft packaging (1), and a second part (2) in the form of a screw cap (5). The screw cap has a top surface (50) and a lateral wall (51) having an internal thread (52) present in the lower region. Above the internal thread there is a thread-free portion (53), in the upper region of which a sliding seal (10) is arranged. The sliding seal (10) presses on a likewise thread-free region (7) of the spout above the external thread (6) disposed on the spout. A screw closure that is leak-proof even during unscrewing is thus achieved.
摘要:
The invention relates to a composite film (10), in particular for packaging (1) in the food industry, having at least one sealing layer (12), which consists of sealable material and is connected, at least indirectly, to a first layer (11) which acts as an outer layer, wherein the sealing layer (12) has a lower melting point than the first layer (11). According to the invention, it is provided that, on that side of the sealing layer (12) which is directed away from the first layer (11), a second layer (13), which acts as an inner layer, is arranged in operative connection with the sealing layer (12), that the second layer (13) has a higher melting point than the sealing layer (12), and that the second layer (13) has at least one through-opening (17; 17a to 17c), which is covered over by the sealing layer (12).
