    DESCRIPTION

    Procedure for obtaining an ethylene absorbing paper and product obtained.

    Object of the invention 5

    The present invention relates to a process for obtaining an ethylene absorbing paper, intended to come into contact with food products, in order to absorb ethylene and thereby delay the ripening process of fruits and vegetables, extending the shelf life. of this. 10

    The invention therefore affects the product obtained by the process, that is, an ideal paper / cardboard for the manufacture of cardboard containers for the storage and transport of fruits and vegetables, free of volatile organic compounds.
     fifteen
    The paper obtained can be equally applicable in the conservation of plants, flowers and the like.

    Background of the invention
     twenty
    Varnish coatings usable in, for example, cardboard boxes and the like intended for the storage and transport of, for example, fruits and vegetables, require that the additive used in the formulation of the varnish be on a positive list of Regulation (EU) No. 10/2011 of the Commission, of January 14, 2011, on materials and plastic objects intended to come into contact with food, since otherwise, said additives cannot be used.

    As is known, ethylene is a plant hormone produced during the ripening of fruits and vegetables, being responsible for changes in respiration rate, tissue softening and other physiological disorders, accelerating the senescence of fruits and vegetables. 30

    While some products and industrial property records relating to ethylene absorber products are known, all of them have a common denominator, which is the fact that the absorber product in question in each case should not come into contact at any time. direct with the product whose useful life is intended to be extended, since they could contaminate them, so these products / registers are not suitable for obtaining paper for the manufacture of boxes, containers and the like for the storage and preservation of fruits , vegetables, plants or flowers.

    Specifically, in the market there are bags containing potassium permanganate that are placed inside the containers that contain the fruits or vegetables to be transported. The problem of this product is due to its high toxicity without being in contact with food.

    There are other embodiments in which different layers of material are used including between them, ethylene absorbers, absorbers that cannot come into contact with food due to their toxicity.

    In this regard, it is possible to cite the patent US 2010092634, in which a lacquer provided with an ethylene absorber is applied to a cardboard layer, although said product as such is not dangerous for the food products in question , said product is applied dissolved in a lacquer, lacquer that by itself if dangerous, containing volatile organic compounds.

    Description of the invention

    The invention is based on achieving a paper with ethylene absorbing properties in which said paper can come into contact with the products to be preserved, without risk of contamination thereto. 5

    Corrugated cardboard is a product used primarily to manufacture containers or boxes for the transport of goods.

    Corrugated cardboard is manufactured in a specific machine known as corrugator. The cardboard is formed by different papers that form the cardboard by the appropriate treatment in the corrugating machine. This can be three or five layers. Each layer corresponds to a paper.

    The cardboard of three layers of paper is formed by placing three rolls of paper in the corrugating machine, in such a way that the intermediate reel will be treated to fold the paper forming the corrugated so that, subsequently, this layer is adhered to in a superior and inferior plane two layers of plain paper.

    Once the cardboard sheet has been formed, it will be subsequently treated by the appropriate method 20, for example dies to form the corresponding containers or boxes.

    The invention proposes that the upper or corrugated paper that will be in contact with the merchandise corresponds to that proposed by the invention.
     25
    More specifically, the process of obtaining is characterized in that it consists in the application by means of conventional flexography techniques on the paper that will constitute the material from which to obtain the containers for the storage and transport of fruits and vegetables, whose conservation status is It aims to extend a varnish to the water free of volatile organic compounds, varnish in which clays, activated carbon and / or 30 zeolites are dissolved, as well as any other ethylene absorbing mineral with a pore size between 3.5 and 5 A and a particle size between 1 and 15 microns, with a percentage of load between 1 and 47%, with a dry weight range between 0.5g / m2 and 15g / m2.
     35
    The type of varnish used, based on water and lacking volatile organic compounds, makes it harmless to contact with the fruit or vegetable products in question.

    In this way a uniform layer of an ethylene absorbing product is applied on the paper, this being usable with the coating for the manufacture of an active container, that is to say for storage and transport of fruits and vegetables, in order to lengthen the shelf life of these fruits and vegetables, and ultimately delay their ripening.

    The product obtained can be considered as a packaging solution that removes ethylene from the environment of fresh fruits and vegetables, slowing the ripening process and consequently the deterioration of plant products, extending their shelf life during packaging.

    It is important to keep in mind that the paper proposed by the invention is the paper that is in contact with food but it could also be the outer paper of the container, 50 so that in the stacks of boxes it would act as an ethylene absorber on the Lower box of the stack formed, therefore, would produce a preservation of the product packaged directly by the internal paper and indirectly with the external paper.

    Description of the drawings

    To complement the description that will then be made and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical implementation thereof, a set of said description is attached as an integral part of said description. planes where, for illustrative and non-limiting purposes, the following has been represented:

    Figure 1. Shows a representation corresponding to a sectional view of a cardboard sheet whose upper layer is formed by the paper proposed by the invention, whose paper 10 is made in accordance with the object of the present invention.

    Figure 2. Shows a perspective view of several cardboard packages forming stacks, the packages of which have the paper object of the present invention.

    Example of practical realization

    "Experimentally, it was split from a varnish to the water (2) to which a solids content of 47% was added, in which zeolites and / or clays and / or activated carbon participate, all of them with a pore size less than 5 A, and a granulometry of less than 7 microns, the mixture 20 being stirred until it is completely homogenized, to be subsequently applied by flexography techniques on a sheet of paper (1), with a dry weight range of 8 g / m2.

    From this sheet of paper (1) a container for the storage of fruits and vegetables was subsequently obtained, being able to experimentally verify how the 25 vegetable products contained in said container had a significantly longer shelf life than products of the same type housed in containers conventional, due precisely to the absorbent properties of ethylene presented by the paper (1) object of the invention.

    As indicated, the paper (1) proposed by the invention, is the paper (1) that is in contact with the food but could also be the outer paper of the container, so that in the stacks of boxes it would act as an ethylene absorber on the bottom box of the stack formed, therefore, a product preservation would be produced directly by the internal paper and indirectly with the external paper.
