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.
  • a horizontally oriented form, fill, and seal packaging apparatus in which the packaging material and the products are fed horizontally rather than vertically.
  • the primary and secondary packaging needs to be sealed in order securely to contain the packaged products.
  • 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.
  • 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.
  • DE-C-362354 discloses packaging sweets in individual packages.
  • US-A-4035984 discloses a wrapping method and apparatus.
  • WO-A-2008/076422 discloses a pillow-shaped secondary package comprising a folded layer of material and having at least one mechanical seal, further having at least one reclosable end.
  • the present invention aims at least partially to meet these needs.
  • the present invention accordingly provides comprising a secondary packaging defining a central cavity containing a plurality of snack food packs comprising 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, wherein the at least one mechanical seal comprises an embossed mechanical interlock between adjacent paper plies and comprises a succession of alternating concave and convex portions inclined to the length direction of the mechanical seal, wherein the package is pillow-shaped and has opposed ends, each end having a respective transverse mechanical seal, and the package further has a longitudinal mechanical seal extending between the transverse mechanical seals.
  • the present invention further provides a packaging apparatus for packaging at least one product within a package, which apparatus is adapted for forming a pillow pack which comprises a secondary packaging containing a plurality of snack food packs and which is adapted to form a sealed package which consists solely of a single folded layer of paper defining a central cavity containing the plurality of snack food packs, the packaging apparatus comprising a vertical 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, wherein the crimping device is adapted to form a pillow-shaped package having opposed ends, each opposed end having a respective first mechanical seal and the crimping device is adapted to form the pillow-shaped package further having a second mechanical seal extending between the first mechanical seals, wherein the at least one crimping device is adapted to form an embossed mechanical interlock between adjacent paper plies which
  • the present invention further provides a method of making packages, each package being a pillow pack which comprises a secondary packaging containing a plurality of snack food packs, which secondary packaging forms a sealed package which consists solely of a single folded layer of paper defining a central cavity containing the plurality of snack food packs the method comprising the steps of: a. providing a folded layer of paper; b. conveying the folded layer of paper through a form, fill and seal machine; and c.
  • each mechanical seal comprises an embossed mechanical interlock between adjacent paper plies and the embossed mechanical interlock comprises a succession of alternating concave and convex portions inclined to the length direction of the mechanical seal.
  • 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 multipacks, 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 are not required 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
  • secondary packaging means the packaging which contains, directly or indirectly, one or more primary packaged products, with the term “secondary packaging” encompassing “tertiary packaging", which may provide a further outer package for the secondary packaging.
  • FIG. 1 illustrates a package in accordance with an embodiment of the present invention.
  • the package 2 comprises a folded layer 4 of paper defining a central cavity 6 containing at least one packaged product 8 (shown in phantom). The thickness of the paper is exaggerated for clarity of illustration.
  • the package 2 has at least one mechanical seal 10 at which plural plies 12, 13, 14 of the layer 4 of paper are mechanically crimped together.

  • each mechanical seal consists of an embossed mechanical interlock extending in a single plane without any folding back of any of the paper plies.
  • the embossed mechanical interlock provides the sole joining mechanism preventing separation of the paper plies.
  • the package 2 is pillow-shaped and has opposed ends 16, 18. Each end 16, 18 has a respective transverse mechanical seal 20, 22. A longitudinal mechanical seal 24 extends longitudinally between the transverse mechanical seals 20, 22.

  • the hydrophobic material may be an exterior coating.
  • no heat seal polymer or adhesive layer is present.

  • the embossed mechanical interlock complementarily shapes the adjacent paper plies 12, 13, 14 in the thickness direction without puncturing the paper. However, such puncturing may optionally be present to provide an enhanced mechanical interlock.
  • the mechanical seal 20, 22, 24 may comprise a selected one of a variety of seal configurations.
  • the seal may include a single series of alternating concave and convex portions 26, 28. These alternating concave and convex portions 26, 28 may have any selected inclination to the longitudinal direction of the mechanical seal 20, 22, 24.
