Problems solved by technology

Other plastics with a higher melting point than PE, such as polyamide (PA) or polyethylene terephthalate (PET), are not used as sealing layers, because these polymers have too high a melting point, so that they are in the packaging area cannot be welded economically or their welds are not strong enough

Embodiment Construction

[0018] exist figure 1 A packaging 1 that can be used especially in food or the food industry is shown in . The packaging is used here in particular for packaging liquid, pasty or block fillings such as milk, water, ketchup or the like. It is particularly preferred to use the composite film to package food products that can be sensed by the sensor, such as water.

[0019] In this exemplary embodiment, the packaging 1 is designed in the shape of a pillow and has, in particular, a strip-shaped upper weld seam 2 and a likewise strip-shaped lower weld seam 3 . Such a package 1 is produced in practice by means of a so-called tube bag machine, in which at least one composite film stored as an endless strip of packaging material is drawn off, folded, filled and welded in a cyclical or continuous manner. Here such a tube bag machine works with a single packaging material web (in which two end regions spaced apart in the longitudinal direction relative to the preferred direction lie o...

Abstract

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).

Description

technical field [0001] The invention relates to a composite membrane, a method for producing a composite membrane and a method for producing a membrane composite part made of at least one composite membrane according to the preambles of the independent claims. The invention also relates to an apparatus for producing composite membranes. Background technique [0002] Such composite films are known in particular from the food industry or the food industry and are used here for the production of packages which contain a defined quantity of food or food, respectively. In particular such composite films are known for the production of so-called tube bag packages. Such a tube bag package is produced in such a way that two opposite edge regions of the composite film or two separate composite films are placed opposite each other, wherein these edge regions are located on opposite sides of the composite film under the introduction of heat and pressure. Weld each other on the sealin...
