Definitions

  • the present invention relates to a package, a packaging apparatus and to a method of making packages.
  • a tubular film having been formed from a roll of packaging film of heat sealable plastic material which has been longitudinally sealed, is fed intermittently through a jaw device.
  • the film forms a flattened tube at the jaw device.
  • the jaw device forms a pair of vertically spaced hermetic heat seals extending transversely across the tube, the seals being located between vertically adjacent packages.
  • the jaw device also cuts through a middle portion, located between the hermetic seals, extending across the tube which separates a lower sealed package containing the packaged product from an upper unsealed package.
  • a lower hermetic seal forms the upper seal of the lower package
  • an upper hermetic seal forms the lower seal of the upper package.
  • the upper package is then filled with product, the tube is advanced downwardly through the jaw device, and then the cycle is repeated when the upper edge of the upper package, and the lower edge of the following package, is disposed between the jaws of the jaw device.

  • the secondary packaging for snack food products typically comprises polymeric film material, for example of a heat sealable polymer, or paper which is adhered by an adhesive layer or a heat sealable polymer coating, in order for such seals to be formed.
  • polymeric film material for example of a heat sealable polymer, or paper which is adhered by an adhesive layer or a heat sealable polymer coating, in order for such seals to be formed.
  • the requirement for such polymers and adhesive to form the packaging not only increases production cost and complexity, but also produces a multi-material package which is difficult to recycle efficiently. Also, when heat sealing is used this increases the energy requirement of the production process, which increases the carbon footprint, i.e. carbon dioxide emissions, of the packaging.
  • the present invention aims at least partially to meet these needs.
  • the present invention accordingly provides a package comprising a secondary packaging defining a central cavity containing a plurality of primary packaged products, the package comprising a folded layer of paper and having at least one mechanical seal at which plural plies of the layer of paper are mechanically crimped together, the mechanical crimping being the sole joining mechanism between the adjacent sealed plies.
  • the present invention further provides a packaging apparatus for packaging at least one product within a package, the packaging apparatus comprising a form, fill and seal machine including at least one crimping device adapted to mechanically crimp together plural plies of a layer of paper to form at least one mechanical seal in a package, the mechanical crimping being the sole joining mechanism between the adjacent sealed plies.
  • the present invention further provides a method of making packages, the method comprising the steps of:
  • the invention is predicated on the finding by the present inventors that mechanical crimp seals can be used in packaging to provide sealed paper packages that are entirely free of adhesive or heat sealed materials. This increases the recyclability of the packaging and reduces the carbon footprint of the packaging.
  • the packages of the invention have particular application in the manufacture of secondary packaging, in the form of multi- packs, for snack food products. Such secondary packaging must be sufficiently robust to provide a secure packaging for the primary packs from the time of manufacture, through distribution, retail sale and final use by the consumer, but the seals of the secondary packaging do not require to be hermetic, since such hermetic seals for protecting the product against environmental degradation are already present in the primary packaging.
  • the package of the invention may also be used for packaging a wide range of other products, as primary or secondary packaging.
  • primary packaging means the packaging containing the actual product to be used or consumed by the user, such as a snack food
