Definitions

  • the present invention relates to the field of modified atmosphere packaging or vacuum packaging of food products by means of packages made of plastic material.
  • the invention relates to a package for food products comprising a tray made of thermoplastic material, having barrier properties with respect to gases and having absorbing power with respect to any liquid released by the food products, and a hermetically sealed cover for said tray.
  • the present invention relates to a tray to be used in the aforesaid package and a process for the preparation of such tray.
  • the second technique foresees instead the use of a tray of expanded plastic material wrapped externally by a gas-impermeable film.
  • the food product is placed onto the bottom of the tray and this is closed by means of a plastic material film which is impermeable to gases.
  • a modified atmosphere is set inside it in the above mentioned way.
  • the third technique foresees the use of a tray made of expanded plastic material which is rendered gas-impermeable through the coupling of a film provided with gas-barrier properties onto the inner face of the tray. Before sealing it with a cover of gas-barrier film, the replacement of the air of the package with a suitable gas mixture is carried out.
  • a drawback of the tray obtained by means of the aforesaid third technique is the impossibility of absorbing the liquids released by the food products, apart from using an absorbing pad between the food product and the bottom of the tray, which, however negatively influences the production costs and complicates the operations of disposal and recycle of the packages after use.
  • a problem which has been encountered with the first two above mentioned techniques is the impossibility of removing completely the oxygen from the inner atmosphere of the tray, as the closed-cell structure of the trays in expanded plastic material holds air, notwithstanding the application of vacuum, in order to release it gradually in the space above the food product.
  • oxygen scavengers chemical substances adapted to neutralise the residual oxygen
  • iron and its derivatives in presence of acids such as iron and its derivatives in presence of acids (US 5 698 250).
  • Patent Application WO 00/46125 describes a tray having absorbing properties which is suitable for vacuum packaging or modified atmosphere packaging of food products which may release liquids.
  • a tray consists of a structure made of open cell plastic material enclosed between two films of which at least one is impermeable to the gases respectively applied onto its inner and outer surface.
  • the film applied onto the inner surface is interrupted by perforations in order to allow the liquid to penetrate into a predetermined portion of the underlying open-cell structure.
  • said portion is sealed by welding the two films in predetermined points in order to prevent the liquid provided inside it from migrating into the remaining open-cell structure of the tray.
  • the films may be welded or glued in correspondence of the cutting surfaces provided at the ends of the edge in order to prevent the liquid from migrating outside of the tray.
  • the technical problem at the basis of the present invention is that of providing a package for modified atmosphere packaging or vacuum packaging of food products susceptible of releasing liquids which would be of easier and more economical manufacture and which would allow to maintain substantially unaltered the gas atmosphere set inside it or the vacuum before use.
  • a vacuum or modified atmosphere package for food products which are susceptible of releasing liquids, comprising:
  • said tray consists of the aforesaid upper and lower layers and of a further layer arranged, at least in correspondence of the bottom, above the aforesaid upper layer and consisting of a non-expanded film or foil of plastic material, provided with through holes or slots on at least part of its upper surface.
  • such film or foil is rendered opaque, to allow the concealment of the absorbed liquid.
  • the opacification may be realised through incorporation of titanium dioxide into the plastic material.
  • the gas-barrier composite film defining the cover is preferably adhered to the folded-up edge of the tray by means of heat sealing.
  • Such film may be identical to the gas-barrier composite film which defines the lower layer of the tray and which is arranged above the upper layer of the tray in correspondence of the edge as a consequence of the folding.
  • the gas-barrier composite film defining the lower layer and the cover of the tray is a multilayered film comprising at least one gas-barrier layer in plastic material and at least one layer made of a thermoplastic material.
  • further layers may be foreseen in order to provide the structure of the aforesaid film with the desired mechanical and thickness characteristics.
  • the material forming the gas-barrier layer may be chosen from the group comprising polymers and copolymers of ethylene vinyl alcohol (EVAL, EVOH), nylon, polyvinylidene chloride (PVDC), poly- or copolyamides and combination thereof.
  • EVAL ethylene vinyl alcohol
  • PVDC polyvinylidene chloride
  • the aforesaid material is a polymer or copolymer of ethylene vinyl alcohol or nylon.
  • multilayered barrier film of the above indicated type suitable to the purposes of the present invention are those described in the US Patent 4,735,855.
  • Examples of particularly preferred multilayered gas-barrier films are the multilayered films produced and sold by the Firm B-PACK having a thickness of 50-60 micron and comprising a gas-barrier layer consisting of EVOH and two layers consisting of polyethylene (PE) and polystyrene (PS), respectively.
  • the plastic material which forms the expanded foil having substantially open cells and the non-expanded film or foil of the tray is preferably chosen from the group comprising polystyrene, polypropylene, polyethylene, polyethylene terephtalate, polyvinyl chloride and their copolymers. Polystyrene is particularly preferred.
  • the grams per square meter of the foil of open-cell thermoplastic material are preferably comprised in the range from 150 to 350 g/m 2 .
  • the surfactant provides the capacity of absorbing aqueous liquids by the foil of open-cells thermoplastic material.
  • It can be chosen among the conventional anionic, cationic and nonionic surfactants and is preferably a salt of a sulphonic acid having the formula R-SO 3 H or of a sulphonic ester having the formula R-OSO 3 H, wherein R is chosen from the group comprising alkyl and alkylaryl, with an alkaline metal or an alkaline-earth metal.
  • a surfactant which is particularly useful for the purposes of the present invention is the aliphatic sulphonate sold by the firm NOVACROME with the name HOSTASTAT SYSTEM E 3904®.
  • the layer of expanded open-cells plastic material advantageously contains a finely-divided solid material able to absorb the aforesaid smelly substances.
  • a material like this is preferably chosen from the group comprising aluminium oxide, bentonite, kaolin, activated carbon, zeolites, synthetic polymers having a high melting point such as polyphenyloxide and polyimmides, graphite, mica, diatomaceous earth, pumice and clay.
  • the packaging according to the present invention allows preserving perishable food products, such as meat and fish, for several days without any remarkable deterioration in their organoleptic and microbiological properties, concealing the exudate and absorbing possible smelly volatile substances into the layer of open-cells expanded plastic material.
  • the packaging according to the present invention has the advantage of maintaining constant the atmosphere originally set inside it without any gas transportation taking place towards the outside or the inside of the package through the upper layer of open-cells thermoplastic material and the cutting surfaces of the tray provided in correspondence of the ends of the edge.
  • the aforesaid cutting surfaces are turned towards the inside of the tray through the edge folding and are arranged below the gas-barrier composite film which forms the cover, preventing in such a way any exchange of gas with the outside.
  • the air inside the tray may be completely removed by virtue of the open-cells structure of the layer of expanded plastic material and eventually replaced with the gaseous atmosphere of desired composition chosen as a function of the food product to be packaged.
  • the absorption of the liquids released by the food products is not provided by the interposition of an absorbing pad between the food product and the bottom of the tray, but rather by exploiting the absorbing properties of the layer of expanded open-cells plastic material containing a surfactant.
  • a material different from the plastic material of which the tray consists is thus avoided, i.e. a cellulosic material such as paper or paperboard, thus facilitating the disposal or recycle operations of the packages after their use.
  • the tray of the aforesaid package comprises two layers and is obtained through a process according to any one of the claims 15 to 18.
  • the tray of the aforesaid package comprises three layers and is obtained through a process according to any one of the claims 19 to 24.
  • the coupling of the foil of open-cells thermoplastic material with the gas-barrier composite film and with the non-expanded foil may be realised by means of hot rolling, use of adhesives or any other method conventionally used for this purpose.
  • the coupling by means of hot rolling is particularly preferred.
  • the foil of open-cells thermoplastic material obtained through the conventional techniques of annular or flat-head extrusion with injection of expanding gases, may be initially hot-rolled with a non-expanded film or foil obtained through coextrusion or subsequently extruded through the techniques known as "extrusion coating", obtaining a first composite leaf.
  • Such first composite leaf is perforated and rolled, in-line or out-of-line, with a gas-barrier composite film.
  • This latter rolling operation is preferably carried out at a temperature comprised in the range 185-210 °C whereas the rolling of the foil of open-cells thermoplastic material with a non-expanded film or foil is preferably carried out at a temperature of 160-180°C.
  • the holes or slots in the non-expanded film and in the foil of open-cells thermoplastic material may be made in a conventional way, for example by means of punching machines. Such perforations allow the passage of the liquid released by the food product contained in the tray into the foil of open-cells thermoplastic material.
  • thermoforming of the semifinished tray and the folding of the respective edge are carried out in a conventional way, preferably by thermoforming in a dedicated mould at a temperature comprised in the range 160-220°C.
  • thermoforming operations may be carried out in sequence in a single mould or in different moulds using suitable conventional methods, such as vacuum suction, compressed air injection, mechanical methods, etc.
  • the package according to the present invention is obtained by means of procedures already known in the art, for example from the US Patent 5,744,181.
  • the food product to be packed is placed onto the bottom of the above described tray and the tray is sealed under vacuum or under modified atmosphere by adhering a gas-barrier composite film onto the lower layer of the tray in correspondence of the folded edge.
  • the aforesaid gas-barrier film is adhered onto the lower layer of the tray in correspondence of the folded edge through thermoforming.
  • the package according to the invention may be under vacuum or under modified atmosphere.
  • the modified atmosphere is obtained through application of vacuum and subsequent injection of inert gases, such as nitrogen and carbon dioxide, or of mixture containing oxygen according to the kind of food product to be packed and preserved.
  • a package according to the invention comprises a tray 1 and a cover 2.
  • the tray 1 has a bottom 3 onto which a food product 4 is placed before its packaging and side walls 5 which end up in a folded edge 6.
  • the structure of the tray 1 consists of a foil 7 made of expanded polystyrene having substantially open cells, whose upper surface is coated by a non-expanded polystyrene film 8 and whose lower surface is coated by a multilayered film 9 comprising a gas-barrier layer made of EVOH or nylon.
  • the film 8 has a plurality of holes 10 of predetermined diameter that extend into the thickness of the underlying expanded polystyrene foil 7 by a predetermined amount so as to allow the liquid released by the food product 4, in this specific instance meat, to penetrate into the substantially open cells of the foil 7 passing through such holes 10.
  • the open cell structure of the foil 7 has a close network of capillary void channels which put the single cells in communication and allow them to receive and keep the liquid penetrated through the aforesaid holes 10.
  • the liquid is kept like by a sponge, and, because of the strong capillary interactions between the void channels and the liquid, it cannot return onto the upper surface of the bottom 3 of the tray 1 by passing through the holes 10, even if this is inclined or even turned upside down.
  • the penetration of the liquid is also enhanced by the presence of a surfactant in the foil 7; the surfactant, in fact, remarkably reduces the natural water repellency of the plastic material, increasing the adhesion forces between the solid (plastic material) and the liquid until these overcome the cohesion forces between the molecules of the liquid, thus allowing the liquid to penetrate into the structure provided with substantially open cells of the foil 7 through the holes 10.
  • the folded edge 6 has a substantially U-shaped cross-section and comprises a first portion 11 protruding from the side walls 5 linked to a second folded portion 12.
  • the multilayered barrier film 9 is arranged above the corresponding portion of the foil of expanded polystyrene 7.
  • the cover 2 consists of a multilayered barrier film and is applied onto the tray 1 through heat welding in correspondence of the second portion 12 of the folded edge 6. Such a cover 2 is applied at the end of the packaging procedure, after having created the vacuum or modified the atmosphere inside the tray 1 in which the food product 4 has been placed.
  • the package according to the invention has the advantage that the liquid released by the food products may be absorbed onto the entire inner surface of the tray because of its structural features which foresee an intermediate absorbing layer consisting of a foil of thermoplastic material with substantially open cells. Further on, any smelly volatile substances released by the food product (for example fish) may be absorbed by the active substances included into the porous open-cells foil.
  • a further advantage of the package according to the present invention is the high effectiveness of the heat welding of the cover with the folded edge of the tray because, as a result of such folding, the materials which are welded together may be identical to each other or extremely compatible.
  • a foil made of expanded polystyrene with substantially open cells having a weight (grams per square meter) of 300 g/m 2 , a thickness of 4,5 mm and a density of 60 g/l, was prepared by extrusion of a suitable mixture.
  • the foil so produced was immediately sent to a hot rolling station in which a OPS-type opacified non-expanded polystyrene film, having a thickness of 25 micron, was applied in correspondence of a surface of such foil by rolling at a temperature of 160°C.
  • the composite leaf thus obtained was perforated in correspondence of the free surface of the non-expanded polystyrene film by means of a plurality of metal nails.
  • a multilayered barrier film of the PE//EVOH//PS type, produced by B-pack and having a thickness of 60 micron was applied in correspondence of the free surface of the aforesaid foil, thus obtaining a perforated composite leaf.
  • This last rolling was carried out at a temperature of 170°C and a conveying speed of 15 m/min.
  • the perforated composite leaf was sent into a thermoforming machine wherein it was taken to an average temperature of 200 °C and then thermoformed in a suitable mould obtaining a tray according to the present invention.
  • the tray was sent to a packaging machine comprising a chamber equipped with a suitable mould and with apertures for the air intake and/or the inlet of a gaseous mixture.
  • the cover consisted of a multilayered barrier film of the PE/EVOH/PE type and had a thickness of 50 micron.
  • the chamber was then closed, the air contained therein was evacuated by applying a reduced pressure of 1-4 millibar and afterwards a gaseous mixture consisting of 70 % oxygen and 30 % carbon dioxide was introduced into the chamber.
  • the aforesaid cover was heat welded onto the folded edge of the tray obtaining a package according to the invention.
