Definitions

  • This invention relates to the field of packaging and in particular to the packaging of food products.
  • This technique allows to quickly package different products, among which food products, starting from a sheet of a plastics material, which is folded over the product and thermo-welded at its rims so as to form a sort of tubular bag encasing the product.
  • the sheet of plastics material generally consists of two films of a thermoplastic material bonded to one other, typically by means of an adhesive.
  • One of these films generally has oriented fibers, whereas the other one has non-oriented fibers.
  • the problem underlying this invention was that of providing a package which might enable a safe opening by the consumer, avoiding the risk of tearing the envelope and thus ensuring the re-closeability of the package.
  • a package of a flexible plastics material for foodstuff comprising a bag closed at its opposite ends by respective weldings, obtained according to the so-called flow-pack technique from a sheet consisting of a first film of a plastics material with oriented fibers bonded to a second film of a plastics material with non-oriented fibers, characterized in that said sheet shows a plurality of zones of bonding discontinuity between said first and second films in proximity to at least one of said weldings.
  • the weldings are preferably thermo-weldings.
  • the films are made of a plastics material chosen from polyethylene and, advantageously, polypropylene.
  • a package according to an embodiment of the present invention comprises a tubular bag 1 enclosing a food product, closed at its opposite ends by transversal thermo-weldings 2, 3.
  • the bag 1 is obtained by flow-pack technique from a sheet 4 of a plastics material consisting of two films 4a, 4b, bonded together by means of an adhesive 6.
  • One of these two films is of a thermoplastics material with oriented fibers, whereas the other film is of a thermoplastic material with non-oriented fibers.
  • the spaces among the spots coated with the adhesive represent zones 5 of bonding discontinuity between the films.
  • Fig. 3 shows a sheet 4 of plastics material used to make the package according to the invention.
  • This sheet is produced by a conventional machine for bonding films of plastics material, using a cylinder for laying an adhesive, which has been suitably arranged in order to obtain a so-called "in register" deposition.
  • the adhesive is laid onto the surface of the film to be bonded in such a way that for certain lengths of the film the whole surface is coated whereas, for other lengths, the adhesive is laid according to a dotted pattern or, in any case, in such a way that the surface of the film is not wholly coated.
  • the sheet obtained by bonding the two films will therefore show lengths in which the two films have a continuous adhesive layer interposed between one another alternating to lengths in which the two films are only bonded at certain areas.
  • the thus obtained sheet after being wound onto a reel, is used to produce the package according to the invention, by using the conventional apparatus of the flow-pack technique.
  • the adhesive for bonding the two films can be chosen among those commonly used in the flow-pack technique and is preferably an adhesive suitable for food packages.
