ART E P R EV IO P R E V ART
Desde hace un tiempo que se ha incorporado en diferentes materiales nanopartículas de cobre para conferir a su superficie cualidades antibacteriales y antivirales. Es posible ver en superficies de atención que incluso las cubiertas han sido reemplazadas derechamente por cobre, esperando que el contacto permanente entre las personas de uno y otro lado del mostrador no se vean expuestos a microorganismos que pueden quedar en la cubierta. Igualmente, se han lanzado al mercado, como consecuencia de la pandemia originada por el Covid -1 9, que existen mascarillas que están impregnadas en nanopartículas de cobre o que incorporan pequeños flejes de cobre en su entretela con el fin de crear una barrera lo más eficiente posible a los patógenos del medio ambiente, evitando que ingresen vivos a las vías respiratorias de las personas. For some time now, copper nanoparticles have been incorporated into different materials to give their surface antibacterial and antiviral qualities. It is possible to see in attention surfaces that even the covers have been directly replaced by copper, hoping that the permanent contact between the people on both sides of the counter will not are exposed to microorganisms that may remain on the cover. Likewise, as a consequence of the pandemic caused by Covid-19, it has been launched on the market that there are masks that are impregnated with copper nanoparticles or that incorporate small copper strips in their interlining in order to create a barrier as close as possible. efficient as possible to pathogens in the environment, preventing them from entering the respiratory tract of people alive.
Nanopartículas corresponde a un conjunto de átomos unidos entre sí que, en términos de dimensiones, se encuentran entre los 1000 y los 5 nanómetros de diámetro. Las que están constituidas de cobre tienen la facultad de interaccionar fu ertemente con organismos como virus y bacterias, con el propósito de eliminarlos a partir de interacciones y reacciones bioquímicas. Es por este motivo que, en particular, las nanopartículas de cobre son ampliamente utilizadas para fines de desinfección . Nanoparticles correspond to a set of atoms linked together that, in terms of dimensions, are between 1000 and 5 nanometers in diameter. Those that are made of copper have the ability to strongly interact with organisms such as viruses and bacteria, with the purpose of eliminating them through biochemical interactions and reactions. It is for this reason that, in particular, copper nanoparticles are widely used for disinfection purposes.
Las nanopartículas de cobre tienen principalmente la capacidad de ceder y captar electrones, y tienen la posibilidad de interactuar con la luz, moléculas, virus y bacterias. Copper nanoparticles mainly have the ability to give up and capture electrons, and have the ability to interact with light, molecules, viruses and bacteria.
En el caso particular de los virus, el mecanismo de acción de las nanopartículas de cobre se basa en que éstas inactivan una enzima proteasa que juega un rol fundamental en la replicación viral. Esta enzima proteasa actúa como catalizador de reacciones químicas. Por lo tanto, son aceleradores bioquímicos y funcionan bajo el principio fu ndamental de la disminución de la energía que se necesita para que ocurra una reacción. En este caso el rol del cobre es alterar las estructuras moleculares enzimáticas y sus funciones. In the particular case of viruses, the mechanism of action of copper nanoparticles is based on the fact that they inactivate a protease enzyme that plays a fundamental role in viral replication. This protease enzyme acts as a catalyst for chemical reactions. Therefore, they are biochemical accelerators and work under the fundamental principle of decreasing the energy needed for a reaction to occur. In this case, the role of copper is to alter the enzymatic molecular structures and their functions.
Por otro lado, las nanopartículas de cobre provocan un daño importante en las envolturas f osf o I i píd i cas , que se caracterizan por estar constituidas por moléculas que poseen un extremo que es soluble en agua, y otro que rechaza el agua. Entonces existe una impermeabilidad selectiva del medio interno y externo en estos virus. (Doctor Freddy Celis Bozo, UPLA, Mayo 2020). On the other hand, the copper nanoparticles cause significant damage to the phospholipid envelopes, which are characterized by being made up of molecules that have one end that is soluble in water, and the other that rejects water. So there is a selective impermeability of the internal and external environment in these viruses. (Doctor Freddy Celis Bozo, UPLA, May 2020).
En publicaciones del arte previo es posible encontrar variada información respecto de film que poseen alguna forma de cobre incorporada. Por ejemplo, la patente GB978200 revela dentro de sus ejemplos una composición de pigmentos que se basa en lacas acrílicas con mezclas de pigmentos. Estas lacas se basan en una Mezcla de vehículos que consiste en 85.4% de éster acrílico mixto Polímero (ACRYLOID A-1 01 ) 14.6% de Ftalato de butilbencilo (como plastif ¡cante) y una Mezcla solvente que consiste en un % de monoacetato de etilenglicol monoetiléter % de metil etil cetona% Tolueno. Una laca acrílica azul de ftalocianina de cobre (CPC) (hecha de manera convencional en un molino de bolas) consta de 3,2 partes de azul de ftalocianina de cobre 66,2 partes de mezcla de vehículos 30,6 partes de mezcla de solvente AB Pigmento en escamas de plata (Ejemplo IX) 4 75 pts 4 75 pts. Esta compo sición es útil para elementos flexibles de embalajes. No obstante, a diferencia de la presente solicitud, no se aprecia que que los pigmentos que se asocian a la película sean nanopartículas, como tampoco que la película se adhiera por efecto de la presión. In prior art publications it is possible to find varied information regarding films that have some form of incorporated copper. For example, patent GB978200 discloses within its examples a pigment composition that is based on acrylic lacquers with mixtures of pigments. These lacquers are based on a Vehicle Mixture consisting of 85.4% mixed acrylic ester Polymer (ACRYLOID A-101) 14.6% Butylbenzyl Phthalate (as plasticizer) and a Solvent Mixture consisting of 1% benzyl monoacetate. ethylene glycol monoethyl ether % methyl ethyl ketone % Toluene. A copper phthalocyanine blue (CPC) acrylic lacquer (conventionally made in a ball mill) consists of 3.2 parts copper phthalocyanine blue 66.2 parts vehicle mix 30.6 parts solvent mix AB Silver flake pigment (Example IX) 4 75 pts 4 75 pts. This composition is useful for flexible packaging elements. However, unlike the present application, it is not observed that the pigments associated with the film are nanoparticles, nor that the film adheres due to the effect of pressure.

The polymeric material that prevents and/or reduces the formation of biofilms on the surface comprises a base material of the polyvinyl chloride, polyethylene, polypropylene or nylon type, to which is incorporated between 0.5 - 5% in mass of core-shell nanoparticles.
Se observa en la publicación de patente que se incorporan nanopartículas de cobre a un material plástico, pero no se observa que se incorporen a una película que se adhiere por presión a cualquier superficie. It is observed in the patent publication that copper nanoparticles are incorporated into a plastic material, but it is not observed that they are incorporated into a film that adheres by pressure to any surface.
La solicitud de patente CL 2001 -1 745 describe una película de envoltura grado alimenticio flexible que incluye un substrato recubierto con un adhesivo sensible a la presión, un elemento de liberación impreso sobre el adhesivo que impide que el adhesivo se pegue a la superficie de un artículo o a sí mismo sin la aplicación de presión y opcionalmente un recubrimiento de liberaci ón sobre el lado opuesto al substrato. Una vez que se aplica presión a la película, la flexibilidad de la película permite al adhesivo que se ponga en contacto con la superficie del artículo o consigo mismo y subsecuentemente se adhiera para mantener la pel ícula en su lugar o para formar una bolsa o saco sellado alrededor del artículo. El contacto activado por presión y adhesion a un artículo o a sí mismo están disenados para formar una unión física fuerte, resistente que sella el contenido o sólido en un contenedor o forme una bolsa o saco sellado alrededor de un artículo sólido. Patent application CL 2001 -1 745 describes a flexible food grade wrapping film that includes a substrate coated with a pressure sensitive adhesive, a release element printed on the adhesive that prevents the adhesive from sticking to the surface of a article or itself without the application of pressure and optionally a release liner on the side opposite the substrate. Once pressure is applied to the film, the flexibility of the film allows the adhesive to contact the surface of the item or itself and subsequently adhered to hold the film in place or to form a sealed bag around the item. Pressure activated contact and adhesion to an article or to itself are designed to form a strong, resilient physical bond that seals the contents or solid in a container or forms a sealed bag or sack around a solid article.
Esta publicación da cuenta de la existencia de películas que se adhieren a presión, pero no se observa que en una de sus caras tenga incorporadas nanopartóculas de cobre. This publication reports the existence of films that adhere to pressure, but it is not observed that one of their faces has copper nanoparticles incorporated.
Respecto de láminas con una cara con autoadhesivo, la literatura describe variadas soluciones. Por ejemplo, la solicitud de patente CL 1 999-2273 describe una lámina envolvente que está constituida por una lámina seccionadle en porciones separadas destinadas a acondicionar un artículo, en particular un producto alimenticio, y a ser cerradas por plegado de la porción alrededor de del artículo. Para facilitar la elección del material de la lámina sin tener en cuenta sus propiedades de retención de los pliegues, la lámina comprende, sobre cada porción, por lo menos una banda de recubrimiento de sellado en frío de adherencia controlada, que asegura el mantenimiento de los pliegues y el cierre del embalaje, después de las fases de plegado de la porción alrededor del artículo a embalar. Puede observarse que la utilización de adhesivos es conocido en el estado de la técnica, sin embargo, no se observa que en una de sus caras se incorporen nanopartículas de cobre. Regarding sheets with a self-adhesive side, the literature describes various solutions. For example, patent application CL 1 999-2273 describes a wrapping sheet that is made up of a sheet that can be divided into separate portions intended to package an article, in particular a food product, and to be closed by folding the portion around the article. . To facilitate the choice of the material of the sheet without taking into account its fold retention properties, the sheet comprises, on each portion, at least one band of cold-seal coating with controlled adhesion, which ensures the maintenance of the folding and closing of the package, after the phases of folding the portion around the item to be packaged. It can be seen that the use of adhesives is known in the state of the art, however, it is not observed that copper nanoparticles are incorporated on one of its faces.

Una modalidad preferida de ejecución de la invención corresponde a una película flexible (1), como por ejemplo de las que se presentan en rollos de plástico delgado o similar, cuya adherencia se produce por la presión y el estiramiento del material sobre el objeto aplicar. En la cara interior (2) de la película flexible no se le aplica ningún componente en especial, ya que la adhesión (5) a la superficie donde se coloca se ocasiona por la presión sobre el objeto en particularmente, en donde dicha presión genera calor y el estiramiento de la película flexible (1) permitiendo la adherencia. En la cara externa (3) de la película flexible (1 ) se ha dispuesto de una capa con nanopartículas de cobre (4), la cual es aplicada en sustrato, quedando las nanopartículas de cobre uniformemente distribuidas en la la cara externa (3). A preferred embodiment of the invention corresponds to a flexible film (1), such as those that are presented in rolls of thin plastic or the like, whose adherence is produced by the pressure and stretching of the material on the applied object. No particular component is applied to the inner face (2) of the flexible film, since the adhesion (5) to the surface where it is placed is caused by pressure on the object in particular, where said pressure generates heat and the stretching of the flexible film (1) allowing adherence. On the external face (3) of the flexible film (1) there is a layer with copper nanoparticles (4), which is applied to the substrate, leaving the copper nanoparticles evenly distributed on the external face (3). .
El material del cual está conformada la película flexible (1 ) puede ser, además del plástico (polieti leno) , vinilo, PVC transparente (policloruro de vinilo) o papel.
