Definitions

  • the invention relates to a packaging machine for the continuous production of multi-layer film packaging using a plurality of film webs comprising an elongate machine frame with at least two support zones for the support of packaged goods, a supply for a top film, a bottom film and at least one intermediate film, each in the form of film webs.
  • Packaging often consists of two merged foils. Such films are processed on packaging machines usually in the form of film webs. For this purpose, the film webs are guided in funding and divided by cutting tools in defined sections of film. Conventional packaging often consists of a bottom sheet formed in troughs and a top sheet sealed thereon.
  • Packaging from a lower film formed in troughs, packaged goods introduced into the trough and a top film sealed on the trough have long been known. These are created on thermoforming packaging machines.
  • the lower film is withdrawn from a roll and cyclically transported with a film transport chain, also referred to as a clip chain or staple chain transported.
  • a film transport chain also referred to as a clip chain or staple chain transported.
  • depressions are formed from the flat lower film.
  • Packaging products are inserted manually or automatically into these hollows.
  • the top film is added, which is sealed in a sealing station on the lower film, so as to create closed containers.
  • the upper film for closing the packages is brought from above to the lower film and is subsequently parallel to the lower film, to be guided to the sealing tool. The sealing takes place on the substantially flat edges that surround the shaped hollows of the lower film.
  • multilayer film packaging are known.
  • SAM Kuchler Knowler Electronics GmbH
  • multi-layer packaging for perishable foods such as sliced sausage and meat products and sliced cheese, consisting of a bottom foil, one or two intermediate films and a top film.
  • the transparent films can be peeled off film by film, so that after removal of the top film, the first layer of food is released, while the further enclosed food in the still closed chambers longer protected from environmental influences kept.
  • Such packages are i.d.R. with appropriate machines. directly in grocery stores, e.g. produced at the counter, wherein the food-cut goods are stored by the slicing machine on previously created individual film sections and then at least partially closed without the use of vacuum or inert gases.
  • the application of a vacuum or inert gas is not provided and also not readily possible.
  • the machines include a slicing machine that processes fresh barware, e.g. Sausage, cuts, on a film section hangs up (one layer, for example, four staggered slices), an intermediate film section hangs up, the secondmaschinesgutlage offset deposited on the intermediate film, a further intermediate film section hangs and the third and last layer offset on the intermediate film two stored. Now, the last film section is placed and the shingled unit passes into the welding station to be welded at the edges to the four corners through the four foils.
  • Multi-layer packaging and a method for their production are known, but no packaging under vacuum or exchange of ambient air is made possible against a protective gas.
  • the special embodiment of the films according to the present invention can not be suggested by this.
  • the packaging machines used for the process according to the invention are machines derived from conventional thermoforming packaging machines. They have an elongate machine frame, in or on which there are support zones for the support of the preferably flat packaged goods in or on the guided in the context of the packaging machine films.
  • the lower film is pulled off a roll and held on both sides on the outer film edge of the film web in each case a film transport chain and transported intermittently.
  • the packaged product is placed flat on the lower film in the first edition zone.
  • Cuttings may, for example, be in the form of one or more partially overlapping shingles consisting e.g. from 2 to 10 slices, to be hung up.
  • the lower film is not cup-shaped and substantially flat.
  • the packaging machine may alternatively also have a processing station for forming troughs (forming station or thermoforming station) before the first support zone.

  • the packaged goods per cycle in two or three tracks on the lower film is placed to form two or three multi-layer packaging per between the edges of the film forming portion of the film web.
  • the application of the packaging material can be done manually or mechanically by means of a slicer (disc cutter) with storage device and / or conveyor belt directly on the film web. Underneath the film (s) there is advantageously, in the region of the support zone (s), an insertion template designed according to the cycle and the tracks.
  • the supply of the first intermediate foil follows from a roller either deflected from above or led from the side over a deflection triangle. After feeding the intermediate film, this is aligned parallel to the lower film.
