Sector de la técnica Technical sector
La presente invención está relacionada con el envasado de productos vegetales, tales como frutas, verduras o flores, y otros productos perecederos, proponiendo un sobre de absorción destinado para colocarse en las cajas o bolsas de envasado de dichos productos, con el fin de eliminar el etileno y otros gases perjudiciales (etanol, acetaldehído, etc.) que son producidos por los productos vegetales y otros productos perecederos, así como las esporas y microorganismos presentes en la atmósfera de los envases de los mismos y que inducen a la maduración y el deterioro de los productos envasados. The present invention is related to the packaging of plant products, such as fruits, vegetables or flowers, and other perishable products, proposing an absorption envelope intended to be placed in the boxes or packaging bags of said products, in order to eliminate the ethylene and other harmful gases (ethanol, acetaldehyde, etc.) that are produced by plant products and other perishable products, as well as the spores and microorganisms present in the atmosphere of their packaging and that induce maturation and deterioration of packaged products.
Estado de la técnica State of the art
Es habitual el envasado de productos perecederos, como las frutas, hortalizas, flores, etc., en bolsas o cajas de distintos tipos, donde por las propias características de dichos productos se produce una atmósfera con distintos gases (etileno, sulfhídrico, etc.), esporas, microorganismos, humedad y otros gases que inducen la maduración y el deterioro de los productos envasados, reduciendo la vida útil de los mismos. The packaging of perishable products, such as fruits, vegetables, flowers, etc., is common in bags or boxes of different types, where due to the characteristics of these products, an atmosphere with different gases (ethylene, hydrogen sulfide, etc.) is produced. , spores, microorganisms, moisture and other gases that induce maturation and deterioration of packaged products, reducing their shelf life.
Para evitar el problema de la aceleración del deterioro y de la maduración por esa atmósfera perjudicial que se crea en los envases de dichos productos, es conocida la utilización de filtros de absorción de los gases perjudiciales, que se disponen en el interior de los espacios confinados refrigerados en los que se transportan los productos; y también es conocida la utilización de sobres de absorción de dichos gases perjudiciales, que se disponen en las bolsas o cajas de envasado de esos productos. To avoid the problem of acceleration of deterioration and maturation by that harmful atmosphere that is created in the packaging of said products, it is known to use filters for absorption of harmful gases, which are arranged inside the confined spaces refrigerated products in which the products are transported; and it is also known to use absorption envelopes of said harmful gases, which are arranged in the bags or packaging boxes of those products.
Los sobres de absorción de gases que se utilizan actualmente para dicha función, están compuestos generalmente por un medio soporte que forma un receptáculo en el que se aloja un material filtrante. El material filtrante que se utiliza en dicha aplicación suele ser un granulado constituido por arcillas (zeolita, sepiolita, alúmina, piedras diatomeas, etc.) impregnadas de permanganato
de potasio, permanganato de sodio, permanganato de litio u otros permanganatos, o mezclas de dichas arcillas con impregnación de un permanganato. The gas absorption envelopes that are currently used for said function are generally composed of a support means that forms a receptacle in which a filter material is housed. The filter material used in this application is usually a granulate consisting of clays (zeolite, sepiolite, alumina, diatom stones, etc.) impregnated with permanganate of potassium, sodium permanganate, lithium permanganate or other permanganates, or mixtures of said clays with impregnation of a permanganate.
El medio soporte que aloja a dicho material filtrante habitualmente ha sido un material de fibras no estructuradas de polietileno de alta densidad, que presenta una serie de ventajas teóricas, como una gran resistencia, permeabilidad a los gases e impermeabilidad a las moléculas de agua. The support medium that houses said filter material has usually been an unstructured fiber material of high density polyethylene, which has a series of theoretical advantages, such as high resistance, gas permeability and impermeability to water molecules.
Sin embargo, en su uso práctico, se aprecia que los sobres realizados con este tipo de medio soporte dejan pasar moléculas de agua al interior del mismo, y presentan la problemática de que al estar compuesto el material filtrante por un granulado de arcillas impregnadas con un permanganato, en el contacto del permanganato con las gotas de agua el permanganato se disuelve en el agua y, dado que el permanganato es de un color púrpura, traslada este color a las gotas de agua, con lo que éstas se manchan tomando ese color. However, in its practical use, it is appreciated that envelopes made with this type of support medium allow water molecules to pass inside it, and present the problem that the filtering material is composed of a granulate of clays impregnated with a permanganate, in the contact of the permanganate with the drops of water the permanganate dissolves in the water and, since the permanganate is of a purple color, it transfers this color to the drops of water, so that these are stained taking that color.
En esas condiciones, dado que en los envases (cajas y bolsas) de frutas, hortalizas, flores y otros productos perecederos, se generan ocasionalmente fuertes condensaciones, el agua resultante de la condensación puede entrar en contacto con el material filtrante de los sobres utilizados para la absorción de los gases perjudiciales, disolviéndose el permanganato en dicha agua de condensación, la cual al entrar en contacto con los productos envasados deja un color púrpura en los mismos; siendo esto uno de los problemas más importantes del envasado de los productos mencionados, ya que los productos que resultan afectados hay que eliminarlos. Under these conditions, since in the containers (boxes and bags) of fruits, vegetables, flowers and other perishable products, strong condensations are occasionally generated, the water resulting from the condensation may come into contact with the filtering material of the envelopes used to the absorption of the harmful gases, the permanganate dissolving in said condensation water, which when coming into contact with the packaged products leaves a purple color in them; This being one of the most important problems in the packaging of the aforementioned products, since the products that are affected must be eliminated.
Adicionalmente, al entrar en contacto con el agua el material filtrante, se produce además una reducción de la capacidad filtrante de dicho material. Additionally, when the filtering material comes into contact with water, there is also a reduction in the filtering capacity of said material.
Por todas esas circunstancias, es evidente que la formación de los sobres absorbentes con un medio soporte que sea totalmente impermeable al agua y que mantenga una alta permeabilidad a los gases, es primordial para minimizar el problema del manchado de los productos perecederos envasados, sin mermar la efectividad de la absorción de los gases perjudiciales. For all these circumstances, it is evident that the formation of absorbent envelopes with a support medium that is completely impermeable to water and that maintains a high gas permeability, is essential to minimize the problem of staining of perishable products packaged, without reducing the effectiveness of the absorption of harmful gases.
Objeto de la invención
De acuerdo con la invención se propone un sobre para la conservación de productos perecederos, y especialmente para la absorción de los gases que aceleran la maduración de productos vegetales tales como las frutas, verduras o flores, para la aplicación en las cajas y bolsas de envasado de dichos productos. Object of the invention According to the invention, an envelope is proposed for the preservation of perishable products, and especially for the absorption of gases that accelerate the maturation of vegetable products such as fruits, vegetables or flowers, for application in boxes and packaging bags. of these products.
Este sobre objeto de la invención comprende un medio soporte, formado por un cuerpo laminar permeable a los gases e impermeable al agua, configurando dicho medio soporte un receptáculo en el que se aloja un granulado filtrante. El cuerpo laminar del medio soporte está compuesto por una lámina plástica con una elevada permeabilidad a los gases, a la cual va adherida una lámina resistente que aporta solidez, constituyendo un conjunto que presenta una buena permeabilidad a los gases, pero que evita totalmente el paso del agua. Fundamentalmente la lámina resistente es de celulosa pero también puede ser de otros materiales, como por ejemplo tejido no tejido. This envelope object of the invention comprises a support means, formed by a gas permeable and water impermeable laminar body, said support means forming a receptacle in which a filter granulate is housed. The laminar body of the support medium is composed of a plastic sheet with a high gas permeability, to which a resistant sheet is attached that provides solidity, constituting a set that has a good gas permeability, but that totally prevents the passage of the water. Fundamentally the resistant sheet is made of cellulose but it can also be made of other materials, such as nonwoven fabric.
La lámina plástica hace que el sellado, sea por calor, por impulso, por frecuencia, por ultrasonido o por otros medios, no tenga imperfecciones que puedan hacer que con el paso del tiempo pueda penetrar el agua a través del medio soporte; mientras que la lámina resistente dota al sobre de rigidez y resistencia impidiendo que pueda romperse en el contacto con un borde cortante de los productos alojados en el envase de aplicación, con lo cual la lámina plástica puede además tener un espesor pequeño para facilitar el paso de los gases. The plastic sheet means that the sealing, whether by heat, by impulse, by frequency, by ultrasound or by other means, does not have imperfections that can cause water to penetrate through the support medium over time; while the resistant sheet endows the envelope with stiffness and resistance preventing it from breaking in contact with a cutting edge of the products housed in the application package, whereby the plastic sheet can also have a small thickness to facilitate the passage of the gases.
Por otro lado, se ha comprobado que el conjunto de la lámina resistente y la lámina plástica, tiene unas propiedades diferentes que la suma de las propiedades de cada una de las láminas, ya que presenta una permeabilidad a los gases significativamente mayor que la suma de las permeabilidades de ambas láminas, con un mismo espesor de las mismas; aumentando la permeabilidad a los gases si la cara expuesta al gas es la constituida por la lámina resistente. On the other hand, it has been proven that the assembly of the resistant sheet and the plastic sheet has different properties than the sum of the properties of each of the sheets, since it has a gas permeability significantly greater than the sum of the permeabilities of both sheets, with the same thickness thereof; increasing the gas permeability if the face exposed to the gas is constituted by the resistant sheet.
