Definitions

• the invention relates to a packaging film for food, in particular for meat, sausage or fish products, the film for the Is suitable for consumption and to increase the tear resistance a net of the film.
• Such packaging films have a large area of application and make a high-quality replacement for natural intestines.
• they are also suitable for packaging food that one cannot fill in natural casings because of their size or shape.
• General they are for the packaging of all types of protein-containing foods particularly suitable, being with the protein of the food can connect. Basically it can it is animal or vegetable protein.
• packaging films described are not special tearproof; They must therefore, as long as they are not familiar with the protein of the food connected, handled carefully or by additional Measures are reinforced.
• a common measure to protect the film is that you can use a net surrounds that is able to support the weight of the food and the resulting absorb the resulting forces during processing.
• the object of the invention is a packaging film and to provide a method of packaging food, which are of high quality for the packaged food ensure good protection accessible to automation, Allow food to be packaged in various forms and are inexpensive to manufacture or carry out.
• the film and the net are fixed to each other results in essentials Processing advantages. For one thing, the film cannot more and more slide around under the net and consequently none Form more wrinkles that lead to tension or tears elsewhere.
• the composite material made of film and mesh can be much easier and without the risk of tearing into the food you want Bring external shapes. Some shapes are made by the composite material is even possible for the first time, which is new, promotional Presentation opportunities opened. In this context of course, the net and film should be connected before the Foil is processed, especially before the food is filled become.
• the solubility of the Adhesive decisive This can generally be unattractive and disruptive network after the manufacturing, cooking or maturing process can be easily removed because the film is sufficient is kept in shape so that tearing is no longer to be feared is.
• the loosening of the net and foil could be done with exact dimensioning the adhesive effect simply by mechanically tearing off the net respectively.
• dissolving or decomposing the adhesive is advantageous. This can be caused, for example, by prolonged contact with gases or appropriate chemicals. From food law For reasons, water is particularly recommended as a solvent. Should but can find other harmless solvents in the future these are of course equally well used.
• the The film should be permeable to water vapor and oxygen.
• materials are primarily those that deal with the food, especially with their protein. Examples are protein, Starch, modified starch, cellulose, polysaccharides or carrageenan or a mixture of these substances. Particularly suitable are polysaccharide films made from pullulan, carrageenan, genue gum, glycerin, crystalline cellulose, honey wax, alcohol, sugar esters, bean oil, Xantane gum and water. Suitable recipes are, for example Pullulan approx.0.21% carrageenan approx.2.1% genue gum approx. 2.1% glycerin about 1.4% Abicel RC-30 about 1.12% honey wax about 0.07 % Alcohol approx.
• Water-insoluble or sparingly water-soluble film is preferred used, because then the condensation water arising during cooling the film cannot dissolve.
• Net is intended to mean any type of material that essentially meets two requirements: firstly, it must be tear-resistant to ensure the protective properties mentioned for the film. Secondly, it should preferably be permeable to air and water vapor, so that the food can properly ripen therein and can be stored.
• the network is preferably a coarse or fine-mesh fabric, knitted fabric or knitted fabric and consists of natural or synthetic fibers, such as for example, cellulose, cotton, polyethylene, polypropylene and / or Polyamide.
• Particularly suitable adhesives are water-soluble adhesives, for example modified starch and / or collagen.
• adhesives well suited on gelatin basis for example an adhesive with approx. 5% to approx. 30% Gelatin and approx. 70% to approx. 95% glycerin or an adhesive with approx. 50 % to about 90% alcohol and about 10% to about 50% shellac.
• the film along with its net is advantageous along at least some of its Edges connected so that they are a container, in the simplest case one Hose, shapes. Due to the connection with the net, the film can for the first time not only glued along the edges, but also sewn or stapled. This enables a much more stable connection, which opens up numerous new areas of application for the film become.
• the film can be for aesthetic reasons or for branding Marking must be printed.
• the font is preferred attached to the inside, for which the film is transparent or clear.
• the entire film can also be colored.
• the packaging method according to the invention has been adopted of food with the film according to the invention as follows To be presented: First, the film and the net with the help of food law harmless adhesive glued together. Then there are basically two options for further processing. Either the composite material, especially by sewing, Stapling or gluing, formed into a container, openings for Fill and if necessary be released for ventilation and that Network at least predominantly comes to the outside. After that it will Container filled with the food. Alternatively, the molding of the Container directly when filling the food, by wrapping them in the film.
