Definitions

  • the invention relates to a multilayer film for packaging small objects by wrapping the object with the film and secured with a twist, with a cold sealable layer to create an adhesive seal.
  • a multilayer film for packaging small objects by wrapping the object with the film and secured with a twist, with a cold sealable layer to create an adhesive seal.
  • Within the scope of the invention is also a production suitable process and use the slide.
  • a film, all with a reliable twist is a special product, the production of which is associated with considerable costs.
  • a multilayer film of the type mentioned Use as packaging with the formation of a turning envelope is disclosed in EP-A-0217388.
  • the one or applied on both sides to a polypropylene base film Cover layers can be hot or cold-sealable layers can be formed.
  • the present invention has for its object a to create multilayer film of the type mentioned at the outset, which are a secure yet easy to open closure made possible by turning.
  • the slide is supposed to also be easy and inexpensive to manufacture.
  • the cold-sealable layer on both sides outside the for packaging object provided wrapping area and essentially perpendicular to the winding or turning wrap axis is arranged in the form of sealing strips.
  • Suitable materials for the sealing strips are synthetic Cold seals or polymers on the Base of natural or synthetic rubber, in particular based on latex. Such products are for the intended use mentioned here is commercially available.
  • Polyolefins such as polyethylenes or polypropylenes, polyamides, Polyethylene terephthalates or polyvinyl chlorides.
  • the barrier layer against gases, vapors and moisture can through a metal foil made of steel or aluminum, for example be educated.
  • suitable materials for barrier layers are, for example, films made of plastics, such as Polyvinylidene chloride or ethyl vinyl alcohol, or one Layer of ceramic materials, such as Silicon or aluminum oxide or nitride, which in thinner Layer, e.g. in the range of 10 - 500 nm, in vacuo to a Carrier film have been deposited.
  • Barrier layers are metallic layers, e.g. made of aluminium, which are deposited on the carrier by sputtering.
  • Printing on the film can be done with all known printing methods, so e.g. Book, offset, flexo, screen, helio and copper gravure printing, but also laser printing, inkjet, electrophotographic and magnetographic printing processes.
  • the vote, which printing process is used depends on the desired print quality, from the respective technical Conditions and the number of copies.
  • the print image will coated with a protective varnish (release varnish) to ensure adherence to avoid the cold seal layer.
  • the sealing strips are by means of a Printing machine (registered) applied to the film.
  • a Printing machine registered
  • the process is the film of the printing press fed as a tape from a roll, continuously with the Seal strips printed and after applying the seal strips wound up into a roll again.
  • the preferred area of application of the inventive Foil is in the packaging of small items like Sweets, chewing gum and the like.
  • a band-shaped packaging film 10 shown in FIGS. 1 and 2 consists of a carrier film 12 made of e.g. Polypropylene one Thickness of for example 18 microns.
  • the carrier film 12 is with provided a barrier layer 14, for example in the form a thin ceramic layer of silicon oxide on the Carrier film 12 is evaporated. Over the barrier layer 14 a printed image 16 is plotted. The outside conclusion forms a protective layer 18.
  • the carrier film 12 On the inside of the carrier film 12 are in lateral Edge distance a of 10 mm, for example, two sealing strips 20, 21 of a width e of, for example, 10 mm.
  • the total width b of the band-shaped packaging film 10 is for example 75 mm.
  • the application of the sealing strips 20, 21 on the packaging film 10 takes place continuously in a printing press.
  • the band-shaped packaging film 10 a printing machine not shown in the drawing fed to a roll and continuously in the printing press printed with the sealing strips.
  • the film 10 is wound up again into a roll.
  • a release lacquer is provided for the protective layer 18 mentioned above.
  • the width b corresponds to the packaging film 10 of the desired width on the final packaging.
  • the packaging film in to produce a width comprising several strips and the cut to the final width b of the individual band-shaped Packaging films 10 in a further step to make.
  • the final cutting of the band-shaped packaging film 10 to individual winding units 24 through perpendicular to the tape running axis x arranged cutting lines 22 are usually made directly in the packaging machine.
  • Fig. 3 shows a small object 26 in the form of a Candy after wrapping it around with a winding unit 24 a winding or Turning axis y.
  • the essentially cylindrical Wrapping is done by gently squeezing the open ends closed in the area of the sealing strips 20.
  • Fig. 4 shows the packaging after twisting two open ends 28 to a turn.
