Definitions
- the invention relates to a packaging film door Food, in particular for meat, sausage or Fish products, the film being suitable for consumption is and to increase the tensile strength of a network at the Foil is present.
- Such packaging films have a large Field of application and provide a high-quality replacement for natural intestines. Beyond that they are but also suitable for packaging food, because of their size or shape they are not in natural casings can fill. Generally, they are for the packaging of all kinds of protein foods especially suitable, taking with the protein of the food can make a connection. in principle it can be animal or vegetable Act protein.
- packaging films described are not particularly tear-resistant; they must, therefore, as long as they are not familiar with the protein of the food carefully handled or be reinforced by additional measures.
- an artificial sausage casing is known from DE-A 1 217 238 has become, which has a mesh cover on the outside.
- This Mesh cover can be glued to the intestine acting as an inner tube be connected.
- To the inner tube with the net cover bring together, the inner tube at its lower end by sealed a stopper and then slipped over a blowpipe and shirred.
- This blowpipe is connected to a blower, so that the inner tube can be acted upon with internal pressure.
- the upper end of the Inner tube is guided in a large-caliber tube, which at his Outside carries a shirred netting tube that up through a stopper is closed.
- Inner tube and mesh tube should then simultaneously be pulled off above, whereby the inner tube due to the inner Overpressure is pressed against the outer mesh tube, so both Hoses can be glued together.
- the invention has the object, a Packaging film and a method for packaging food which are of high quality, for the packaged food Ensure good protection, accessible to automation, food in a variety of forms to allow packaging and cost In the Production or implementation are.
- the solubility of the adhesive decisive In addition to the composite property is for the invention the solubility of the adhesive decisive. Thereby In general, this can be unpleasant and annoying felt net after the manufacturing, cook or Ripening process can be easily removed again because then the film is held sufficiently in shape, so that tearing is no longer to be feared.
- the film should be permeable to water vapor and oxygen be.
- exemplary protein starch, modified starch, Cellulose, polysaccharides or carrageenan or a mixture called these substances.
- water insoluble or difficult to use water-soluble film because then the during cooling, condensation forms the film can not dissolve.
- net is intended to mean any kind of material that meant essentially two demands fulfilled: First, it must be tear-resistant, to the mentioned To ensure protection of the film. Second, it should preferably be permeable to air and water vapor so that the foods in it are appropriate mature and can be stored.
- the mesh is preferably coarse or fine mesh fabric, knitted or knitted fabric and consists made of natural or synthetic fibers, such as Creel, cotton, polyethylene, polypropylene and / or polyamide.
- Adhesives such as modified starch and / or Collages.
- glues are also gelatin-based well suited, such as an adhesive with about 5% to about 30% gelatin and about 70% to about 95% glycerin or an adhesive with about 50% to about 90% alcohol and about 10 % to about 50% shellac.
- the film along with its net is advantageously long connected at least some of their edges, so that a container, in the simplest case a hose, shaped.
- a container in the simplest case a hose, shaped.
- the film can not only glued along the edges but first also sewn or stapled. This allows a much more stable connection, reducing the film Numerous new applications opened up become.
- the film can be aesthetic Reasons or for brand marking printed be.
- the writing is preferably on the inside attached, to which the film transparent or clear is. Alternatively, however, is a coloring of the entire Foil conceivable.
- the film After filling and after the tire or the heat treatment or at the end of the manufacturing process the film has become insoluble with the food connected and then the network can be removed again become. This is done by simply removing the Net after previous release of the adhesive.
- the release is done partly by the alone Condensation that adheres to the packaged food forms.
- the release of the adhesive has with the aid of a solvent, especially water, the big advantage that the film after removal of the net an aesthetically pleasing surface without adhesive residues.
