Definitions
- a laminar sheet material including a gas and water impermeable layer, a gas permeable and water impermeable layer and a bonding material therebetween containing a catalyst capable of initiating reaction between hydrogen and oxygen to form water.
- oxygen is removed by formation of water which is trapped between the two layers and thus out of contact with the packaged product.
- This invention relates to deoxygenated packages for storing substances such as foods normally subject to oxidative deterioration and to sheet materials from which such packages may be formed.
- the present invention overcomes these diificulties by providing a sheet material which may be shipped and stored without special precautions and which has dry redox catalyst within the sheet material which catalyst is not exposed to the contents of a container formed from the sheet material.
- the present invention for the first time makes possible the packaging of whole dried milk powder in a flexible pouch or envelope at a low cost without the use of any oxygen removing capsule or pellet within the package and yet maintains the powdered milk under suitable conditions to prevent deterioration.
- FIG. 1 is a perspective view of a pouch formed in accordance with the present invention.
- FIG. 2 is a cross-sectional view of the pouch of FIG. 1 along line 22 with the cross section of the pouch material magnified to show the structure of the same.
- a package comprising a hermetically sealed pouch 1 containing a food product such as dried whole milk.
- Pouch 1 is shown as being sealed along three edges as for example at 2, but any other conventional pouch configuration could be used instead.
- the pouch of the present invention is formed from a sheet material having a plurality of layers.
- the layers which are essential to the package are a gas and water impermeable barrier layer 3, preferably composed of metal foil and an inner layer 4 formed of a water impermeable but gas permeable material.
- the catalyst is disposed at 5 between these two layers and thus is in contact with the gas phase of the interior of the package and yet is separated from any solid or liquid product contained therein.
- Material 4 is shown in FIG. 2 to be a resinous plastic material such as polyethylene but this layer may be formed from any equivalent material for example polypropylene or various other suitable polyolefins, cellophane, polyvinyl chloride, rubber hydrochloride, or wax-copolymer blends, such as blends of wax and ethylene-vinyl acetate copolymers.
- an adhesion promoting material 5 As shown in FIG. 2, but if desired the catalyst may merely be applied between layers 3 and 4 before the lamination by sprinkling, brushing, spraying or by depositing electrolytically, electrostatically or from a metal-containing vapor.
- layer 5 is usually very thin, often little more than a monomolecular layer.
- adhesion promoting materials which may be used to assist the adhesion of polyolefin resins applied to metal foil are polyethylene imine, titanium acetyl acetonate, and shellac.
- adhesion promoters commonly referred to as anchor coats, or primers from a solution in a liquid such as isopropyl alcohol.
- a liquid such as isopropyl alcohol.
- adhesion promoting material is vinyl chloride, which may be applied in a form of a solution in either toluene, methyl ethyl ketone, alcohols or combinations thereof.
- Such a coating is commonly applied to metal foil to protect the foil and to promote the adhesion thereto of hot-melt coatings such as wax-copolymer blends.
- layer 5 could as well be an adhesive or glue which could be employed to laminate layers 3 and 4.
- the catalyst is mixed within the adhesion promoting material, this material itself should be gas permeable in order that the catalyst be accessible to the gas phase of the contents of the container. If the adhesion promoting material is not gas permeable, the catalyst could be sprinkled on the surface of layer 5 thereby placing the same in contact with the undersurface of the permeable layer 4.
- the catalyst may thus be incorporated into any adhesion promoting materialin an anchor coat in the case of extrusion coating, in a protective coat in the case of a hot-melt coating, or in an adhesive used to bond the two layers together.
- hesion promoter is defined to include all of these for purposes of the subject specification and claims.
- a further layer 6 of a decorated material such as paper may be placed around the outside of the package for purposes of applying trade names and also to protect the gas impermeable barrier layer against abrasion or the like.
- impermeable layer 3 is shown as being composed of metal, it is to be understood that other substantially impermeable materials may be substituted, for example, polyvinylidene chloride.
- the preferred composition of the catalyst is palladium either in finely divided form such as palladium black or in the form of a thin coating on a carrier such as finely divided alumina.
- Palladium is preferred as the redox catalyst for economic reasons, but it will be obvious to those skilled in the art that equivalent substances such as the other platinum group metals or organic tin compounds can be substituted therefor.
- the product is placed within the pouch and the oxygen is removed from the interior of the same to that extent which is possible by direct flushing with an inert gas, in the present case preferably containing at least 5% hydrogen, or by creating a vacuum within the package and thereafter introducing a gas which contains hydrogen.
- the pouch is then sealed and is ready for placement within a carton, if desired, for shipment and storage.
- Oxygen desorbed from the product packaged is also removed by this system, as is oxygen which enters the package through areas of low level transmission.
- the small amount of water formed from this reaction is believed to be formed in th vicinity of the catalyst between layers 3 and 4.
- the dry food powder is shielded by layer 4 [from any moisture produced by the oxidation reaction.
- EXAMPLE I Stock material was prepared by laminating 30 1b./ ream paper and 0.00035 inch aluminum foil, polyethylene being extrusion coated onto the foil to serve as medium for bonding these layers together. A polyethylene imine anchor coat was applied to the other side of the film as a 0.25 percent solution in isopropanol. 4 lb. of this solution was applied to each ream of material and the solvent subsequently removed by evaporation. This polyethylene imine solution also contained enough finely divided palladium to provide 0.005 lb./ream. A layer of polyethylene 1 /2 mils thick was extruded over this catalyst-containing anchor coat. Similar stock material was made with the catalyst omitted for purposes of comparison.
- a laminated, flexible, sheet material adapted to be formed into a gas impervious container comprising:
- first flexible sheet material layer said first layer being substantially impervious to oxygen and water vapor and chosen from the group consisting of flexible metal foil and polyvinylidine chloride film;
- a second flexible sheet material layer said second layer being substantially pervious to oxygen and hydrogen and being substantially impervious to water and chosen from the group consisting of polyethylene, polypropylene, cellophane, polyvinyl chloride and rubber hydrochloride; and
- a third, bonding layer said third layer being a gaspermeable, adhesion-promoting material entirely disposed between and bonding together said first and second layers, and including, substantially evenly distributed in said third layer, a finely divided catalyst chosen from the group consisting of the platinum metals and adapted to convert oxygen and hydrogen to which said second layer is pervious into water to which said second layer is impervious, whereby any water so formed is efiectively trapped between said first and second layers.
