Abstract
The invention concerns a packaging material comprising two layers delimiting between them a cavity. A substance capable of retaining gas therein is housed in the cavity and one of the layers is permeable to gas ethylene and impermeable to water vapour.
Description
- The present invention relates to packaging materials and more particularly to those intended for the protection of vegetable matter to be preserved.
- Document U.S. Pat. No. 4,528,228 discloses a cushioning pad comprising a layer of cushioning material, a gas-permeable envelope containing this layer, and a chemical composition dispersed in voids in the layer. That document therefore does not disclose two plies that define a cavity between them, nor does it disclose a substance capable of retaining gases housed in the cavity, nor does it disclose that one of the plies is a material permeable to gaseous ethylene but impermeable to water vapor.
- Document U.S. Pat. No. 5,334,623 discloses an absorbent substance. It does not disclose two plies defining between them a cavity in which a substance is found, Furthermore, the subject of that patent is a very particular composition containing tetrazine.
- The subject of the invention is a packaging material that allows the vegetable matter packaged therein to be preserved for a longer time.
- The packaging material comprises two plies defining between them a cavity. According to the invention:
-
- a) a substance, capable of retaining gases in its environment, is housed in the cavity; and
- b) at least one of the plies is made of a material permeable to gaseous ethylene and impermeable to water vapor.
- By placing the substance capable of retaining gases in the cavity, it is prevented from coming directly into contact with packaged vegetable matter in such a way that the substance capable of retaining gases does not have to be of food grade. But most particularly what is created in the cavity is an atmosphere deplete in water vapor and also deplete in gaseous ethylene, which is the representative compound of the volatile gases given off by the respiration of the vegetable matter.
- The active substance (i.e. the substance capable of retaining gases in its environment), which is preferably bonded to the substrate, allows close protection of the vegetable matter or other matter to be preserved. This is because ripening vegetable matter gives of f volatile compounds coming from the respiration of the matter. The discharge of such compounds, and the proximity of these elements of the ripening vegetable matter, causes autocatalysis of the complex mechanism governing the respiration of this matter. The respiratory intensity of the matter is in general characterized by the ratio of the amount of oxygen absorbed to the amount of carbon dioxide discharged, and consequently the amount of organic compounds diffusing from the surface of the ripening matter. The dynamics of this respiration are accelerated by certain of these volatile organic compounds in contact with the outer surface of this substance from which they emanate. This autocatalysis of the respiration and therefore of the ripening process, depends on the content of these compounds in the atmosphere directly in contact with the ripening vegetable matter. To limit this respiratory intensity, it is necessary to limit the volatile organic compounds responsible for certain autocatalysis. To do this, the active material placed in the immediate vicinity of the ripening vegetable matter will make it possible, depending on its characteristics, to adsorb and absorb the essential volatile organic compounds causing the autocatalysis of the mechanisms governing the ripening of all vegetable matter.
- The substance is capable of retaining gases in its environment, especially capable of adsorbing gases, but preferably this active substance is not only capable of adsorbing gases but also of absorbing them. The active substance most particularly preferred is that disclosed in
International Patent WO 00/64577. This is a porous material having the capability of adsorbing about 20 to 30% relative to its dry weight and comprising about 47 to 50% by weight of a silicon/carbon composite structure, about 12 to 20% by weight of carbon, about 5 to 7% by weight of a hydroxyl entity and about 1 to 2% by weight of oxygen. Preferably, this substance comprises, in a peripheral volume corresponding to substantially one-third of the total volume of the matter, about 75 to 85% of pores, the size of which is between 10 and 50 angstroms, and in the remaining central volume about 80 to 90% of cavities whose size is between about 200 angstroms and 2 μn. Its specific surface area may be between 1200 and 2200 m2/g. It may include about 20% by weight of aluminium oxide and about 5% by weight of iodide. Its moisture content may be less than 2% with respect to its dry weight. Preferably, the active substance has a particle size of between 10 and 350 μm. A method for preparing the substance will be found in the aforementioned international application. - The ply made of a material permeable to ethylene and impermeable to water vapor is preferably made of hydrophobic cellulose. The water vapor permeability is preferably between 600 and 1000 g/m2per 24 hours at 38% relative humidity. Preferably, both plies are made of the same material and, also preferably, the substance is bonded to one of the plies so that it is well distributed within the entire housing.
- According to a preferred embodiment, the material of at least one of the plies has open pores with electrical polarity. This has the effect of promoting the gas aspiration chimney effect. Such polarization may have the effect of asepticizing the atmosphere within the cavity.
- The subject of the invention is also a package, at least one of the walls of which is made of a material according to the invention, and also vegetable matter packaged in a package according to the invention.
- The package may be formed by a cornet-shaped packaging paper, by a bridge or by a tray, at least one wall of which is made of a material according to the invention, the vegetable matter being preferably at a certain distance from the packaging material.
