Definitions

  • a known method of improving the storage life of food products intended for display in large stores is to pack the products in a modified atmosphere appropriate for the purpose.
  • Modified-atmosphere packaging is currently predominantly oriented in two different ways.
  • the product is placed in a sufficiently rigid, non-gas-permeable pack and closed in a normally transparent sheet or film of thermoplastic material which is also non-gas-permeable, and the modified preserving atmosphere is injected into the resulting pack.
  • the pack made in this way is sufficiently rigid and a number of such packs can be stacked one on top of the other in a packaging container. These packs are very expensive and not all consumers like them.
  • the product is placed in a conventional pack on a small tray and bound in a gas-permeable stretchable film.
  • the packs are placed side by side, without projecting, in a stout cardboard box which is then sealed with a non-gas-permeable film and the resulting packaging is filled with the modified atmosphere suitable for preserving the individually packed products.
  • the products remain in this condition until the time when they are displayed on the shop counter, at which point the packaging is cut open and the individually packed products are placed in the refrigerated displays where they will be kept in the same way as fresh products that have never had modified-atmosphere treatment.
  • the supporting board which has the important function of distributing the weight of the upper package uniformly over the gas cushion of the lower package, may have containing edges and may be made of, for example, board or a cellular extrusion of a plastic material which is the same as or compatible with that of the envelope of the package in order that all of the pack can be recycled.
  • the packaging 1 comprises at least one sufficiently rigid supporting board 2 made of, for example, corrugated board or an extruded cellular plastic material (see below), which may have small containing edges 102 and on which two or more packs 3 of the food product, individually wrapped in a gas-permeable plastic film, are laid and arranged.
  • a sufficiently rigid supporting board 2 made of, for example, corrugated board or an extruded cellular plastic material (see below), which may have small containing edges 102 and on which two or more packs 3 of the food product, individually wrapped in a gas-permeable plastic film, are laid and arranged.
  • the supporting board 2 with the products 3 is enclosed in a sufficiently flexible sealed envelope 4 made of a sheet or film of non-gas-permeable thermoplastic material, this envelope being filled with the desired gas or gases to produce the modified atmosphere at a pressure sufficient to create a cushion of gas 5 in the top part, the properties of which are such that, after a number of packages 1 have been stacked as shown in Figure 2, a distance 6 is maintained between the underside of the supporting board 2 of the upper packaging and the packs 3 of the lower packaging, this distance being sufficient to avoid contact between said underside and said packs and such as in all cases to avoid damage to said packs.
  • the supporting board 2 has the important function of maintaining the arrangement of the packs 3 of each packaging, uniformly distributing the weight of the upper packaging over the lower packaging, and keeping the stack stable.
  • the supporting board 2 is a quite separate item and can be removed without problems when the packagings are broken and the individually packed products displayed in the refrigerated displays for sale.
  • the supporting board 2 can be made from a sheet of corrugated board or from a cellular or ribbed sheet of an extruded plastic material, preferably the same as or compatible with the plastic material of the envelope 4 of the packages, in such a way that all the parts making up these packs can be completely recycled.
  • valve boxes 9, 109 connected to means capable of aspirating out the atmosphere inside the tubular envelope 104, as seen in Figure 6. After this the same boxes 9, 109 are used to fill the envelope 104 with the gas necessary to produce the modified atmosphere for preserving the products 3, at the pressure required to create the gas cushion 5, as illustrated in Figure 7.
  • the injection of the gas under pressure may, for example, be time-controlled in some appropriate manner and/or means may be provided for sensing the height of said cushion 5.
  • the part 304 of the sleeves 204 which is near the abovementioned expander devices 8, 108 is stretched transversely by these, while the pressure of the preserving gas injected into the pack also stretches it longitudinally, with the result that the parts 304 are fully stretched and without creases, thus being in the best possible condition for subsequent sealing by lines of heat welding 10, 110 using pairs of heat welding bars 11, 111, as illustrated successively in Figures 7 and 8.
  • the devices 8, 108 contract transversely and withdraw from the closed sleeves 204, the heat welding bars 11, 111 return to the rest position and the packaging is removed from the production machine and stacked and the composite pack is placed in the packaging box 7.
