DESCRIPCIÓN DE UNA REALIZACIÓN PREFERENTE DESCRIPTION OF A PREFERRED EMBODIMENT
Tal y como se muestra esquemáticamente en La figura 1 , el procedimiento de fabricación de una estructura en película de PVC para empaque de caramelos, adaptado para su trabajo sobre una película de PVC 12 longitudinal que es desenrollada desde una bobina 1 1 inicial, tras el desenrollado 1 de la bobina 1 comprende: As shown schematically in Figure 1, the manufacturing process of a PVC film structure for candy packaging, adapted for work on a longitudinal PVC film 12 which is unwound from an initial coil 1, after the unwind 1 of coil 1 comprises:
A. Una aplicación 2 en continuo de un producto tipo esmalte sobre una de las caras de la película de PVC 12 longitudinal, y de modo que la aplicación 2 es efectuada sobre la región periférica de la cara de la película de PVC 12, y quedando la región central desafectada por la aplicación 2. A. A continuous application 2 of an enamel-like product on one of the faces of the longitudinal PVC film 12, and so that the application 2 is made on the peripheral region of the face of the PVC film 12, and remaining the central region unaffected by application 2.
B. Una aplicación 3 en continuo del producto tipo esmalte sobre la otra cara de la misma película de PVC 12 longitudinal, y de modo que la aplicación es efectuada sobre toda dicha cara de la película de PVC 12, y con un dibujo determinado. B. A continuous application 3 of the enamel-like product on the other side of the same longitudinal PVC film 12, and so that the application is made on all said face of the PVC film 12, and with a particular drawing.
Tal y como se representa esquemáticamente en la figura 2, la primera aplicación 2 en continuo se efectúa tras el desenrollado 1 desde una bobina 1 1 de la película de PVC 12 longitudinal. As shown schematically in Figure 2, the first continuous application 2 is carried out after unwinding 1 from a coil 1 1 of the longitudinal PVC film 12.
Según se aprecia en la figura 2, la aplicación 2 es efectuada sobre la región periférica de una cara de la película de PVC 12 longitudinal, y quedando la región central desafectada por la misma aplicación 2. As can be seen in Figure 2, the application 2 is carried out on the peripheral region of a face of the longitudinal PVC film 12, and the central region being left unaffected by the same application 2.
Según se aprecia esquemáticamente en la figura 3, a continuación se efectúa una segunda aplicación 3 en continuo del producto tipo esmalte sobre la otra cara de la misma película de PVC 12 longitudinal, y de modo que la aplicación 3 es efectuada sobre toda dicha cara de la película de PVC 12 longitudinal, y con un dibujo determinado. As shown schematically in Figure 3, a second continuous application 3 of the enamel-like product on the other side of the same longitudinal PVC film 12, and so that the application 3 is made on all said face of the longitudinal PVC film 12, and with a particular drawing.
En algunas modalidades de realización preferidas, al menos una de las caras de la película de PVC 12 recibe una impresión de colores antes de la aplicación 2, 3 del producto tipo esmalte. La película de PVC 12 es de polímero de PVC, con formulación libre de plastificante, lo que le imparte la rigidez necesaria para el plegado. El sustrato generalmente se utiliza transparente, pero en algunas aplicaciones podría ser pigmentado (en especial de blanco) o también se encuentra en acabado metalizado, es decir, con un depósito de aluminio superficial que puede alcanzar por ejemplo las 0,03 mieras de espesor. In some preferred embodiments, at least one of the faces of the PVC film 12 receives a color print before application 2, 3 of the enamel type product. PVC film 12 is made of PVC polymer, with a plasticizer-free formulation, which imparts the stiffness necessary for folding. The substrate is generally used transparent, but in some applications it could be pigmented (especially white) or it is also in metallic finish, that is, with a surface aluminum tank that can reach for example 0.03 microns thick.
Una vez extruida, la película de PVC 12 es muy estable y tiene la capacidad de recibir en su superficie tanto las tintas de impresión como el recubrimiento de laca de sellado. Once extruded, the PVC film 12 is very stable and has the ability to receive both the printing inks and the sealing lacquer coating on its surface.
En esta modalidad.de realización preferida, la película de PVC 12 está constituida a partir de Cloruro de Polivinilo valor K 57, el estabilizante tipo Carboxilato y el modificador de impacto que es metacrilato butadieno estireno (MBS). El producto tipo esmalte, en esta realización preferida por la naturaleza del sustrato de PVC, es una resina vinílica, pues es la que mejor se desempeña para la formulación de la composición de recubrimiento y debe ser complementada con un solvente orgánico tipo éster y aditivos específicos para conseguir otras propiedades como antiestáticos, ceras de deslizamiento tipo carnauba y antiestáticos de sales de amonio cuaternario. In this preferred embodiment, the PVC film 12 is constituted from Polyvinyl Chloride value K 57, the carboxylate type stabilizer and the impact modifier which is styrene butadiene methacrylate (MBS). The enamel type product, in this preferred embodiment due to the nature of the PVC substrate, is a vinyl resin, as it is the one that best performs for the formulation of the coating composition and must be supplemented with an organic solvent type ester and specific additives to achieve other properties such as antistatic, carnauba-type slip waxes and antistatic quaternary ammonium salts.
En concreto, en esta modalidad de realización preferida, la resina vinílica es una laca de selle, con una dispersión de copolímeros de resina vinílica en una mezcla de solventes orgánicos tipo éster y un paquete de aditivos que mejoran notablemente su procesabilidad y desempeño en máquina. La laca de selle se suministra en estado líquido a la máquina impresora y en el proceso de impresión se evapora todo el solvente por medio de grandes túneles de secado. Specifically, in this preferred embodiment, the vinyl resin is a sealing lacquer, with a dispersion of vinyl resin copolymers in a mixture of organic ester solvents and a package of additives that significantly improve its processability and machine performance. The sealing lacquer is supplied in liquid state to the printing machine and in the printing process all the solvent is evaporated by means of large drying tunnels.
El objetivo fundamental de la laca de selle es fundirse sobre la superficie de la película de PVC 12, una vez se consiga la temperatura adecuada mediante mordaza de contacto. Esta fusión permite que se genere un selle cohesivo consigo misma y adhesivo con el propio sustrato. Con esto se garantizan las características de hermeticidad e integridad del empaque hacia el producto. The main objective of the sealing lacquer is to melt on the surface of the PVC film 12, once the proper temperature is achieved by contact jaw. This fusion allows a cohesive seal to be generated with itself and adhesive with the substrate itself. This guarantees the tightness and integrity characteristics of the packaging towards the product.
La formulación de la laca de selle es en realidad una disolución de resina vinílica que alcanza el 10% de sólidos en un medio de solventacion de acetato de etilo y acetato de n-propilo. La fórmula se complementa con un agente antiestático líquido del tipo sal de amonio cuaternario, un antiespumante de sílice y una cera natural para facilitar el deslizamiento tipo carnauba. The seal lacquer formulation is actually a solution of vinyl resin that reaches 10% solids in a solvent for ethyl acetate and n-propyl acetate. The formula is complemented with a liquid antistatic agent of the quaternary ammonium salt type, a silica antifoam and a natural wax to facilitate sliding carnauba type.
La resina sólida es disuelta en un reactor con chaqueta de enfriamiento, que previamente ha sido cargado con los solventes y todos los aditivos. El resultado es un laca tipo barniz de apariencia transparente cuyas propiedades de fluidez permiten que pueda ser aplicada sobre la superficie del sustrato dejando el componente sólido sobre el sustrato y permitiendo la evaporación del solvente mediante cambio del estado líquido al estado gaseoso. The solid resin is dissolved in a reactor with a cooling jacket, which has previously been loaded with solvents and all additives. The result is a varnish-type lacquer with a transparent appearance whose fluidity properties allow it to be applied on the surface of the substrate leaving the solid component on the substrate and allowing evaporation of the solvent by changing the liquid state to the gaseous state.
Las principales propiedades de la laca de selle se pueden ver resumidas en la siguiente tabla y deben ser objeto de estricto control durante el proceso de fabricación y almacenamiento.
Figure imgf000009_0001
The main properties of sealing lacquer can be summarized in the following table and must be subject to strict control during the manufacturing and storage process.
Figure imgf000009_0001
En una modalidad de realización preferida, la aplicación 2, 3 del producto tipo esmalte en la película de PVC 12, como por ejemplo laca de selle, se efectúa 25 mediante una impresora o lacadora por el método de rotograbado. In a preferred embodiment, the application 2, 3 of the enamel-like product on the PVC film 12, such as sealing lacquer, is carried out by means of a printer or lacquer by the rotogravure method.
Las prensas por rotograbado disponen de una unidad en donde se acopla un cilindro grabado a unas condiciones de lineatura de celda y profundidad. Esta grabación en forma de celdas, aloja la cantidad de laca precisa que luego de un giro, y mediante contacto directo con el sustrato en un proceso continuo, se deposita en la superficie comenzando de inmediato con el proceso de evaporación de los solventes por efecto de la temperatura de los túneles de aire caliente. Rotogravure presses have a unit where an engraved cylinder is coupled to cell line depth and depth conditions. This recording in the form of cells, houses the precise amount of lacquer that after a turn, and by direct contact with the substrate in a continuous process, is deposited on the surface immediately starting with the process of evaporation of solvents by effect of the temperature of the hot air tunnels.
Adicionalmente al control de las condiciones de proceso y aplicación de la laca de selle, el desempeño exitoso de la estructura está basado en las dimensiones, disposición espacial, geometría, y ángulos en los que se aplica la laca sobre el área de la película. In addition to the control of the process conditions and application of the seal lacquer, the successful performance of the structure is based on the dimensions, spatial arrangement, geometry, and angles at which the lacquer is applied over the area of the film.
Esta configuración permite que cada uno de los pliegues del empaque asegure la sellabilidad y hermeticidad que el producto demanda para su distribución y consumo, permitiendo a la vez que el producto tenga una fácil apertura. Es decir, que se consiga un selle hermético pero pelable. Esta especialización del producto, es el resultado de una investigación profunda del comportamiento del selle, hasta conseguir el ajuste fino que diferencia el resultado. La geometría definida para la aplicación de la laca sensible a la temperatura es también fundamental para el buen desempeño de la estructura. Otro aspecto importante, que complementa las características necesarias de la estructura radica en la diferencia que debe presentar la laca interior respecto a la laca exterior. This configuration allows each of the folds of the package to ensure the sealability and tightness that the product demands for distribution and consumption, while allowing the product to have an easy opening. That is, that a tight but peelable seal be achieved. This specialization of the product is the result of a deep investigation of the behavior of the seal, until the fine adjustment that differentiates the result. The geometry defined for the application of the temperature-sensitive lacquer is also essential for the good performance of the structure. Another important aspect, which complements the necessary characteristics of the structure lies in the difference that the inner lacquer must have with respect to the outer lacquer.
Un aporte importante para el óptimo desempeño de la estructura de empaque es asegurar que cada una de las caras de la película de PVC 12 tenga el recubrimiento adecuado. Por una cara de la película de PVC 12 se coloca el modelo de rombos consecutivos (figura 3) alineados en dirección máquina con punto de contacto en uno de sus vértices. Por la otra cara de la película de PVC 12 la aplicación 2 se hace en forma continua sin obedecer a un diseño particular (figura 2). An important contribution to the optimal performance of the packing structure is to ensure that each of the faces of the PVC film 12 has the appropriate coating. On one side of the PVC film 12, the model of consecutive rhombuses (figure 3) aligned in machine direction with contact point in one of its vertices is placed. On the other side of the PVC film 12 the application 2 is made continuously without obeying a particular design (figure 2).
La laca interior sigue un patrón de aplicación continuo, tal como se puede observar en la figura 2 (zona sombreada), alineada con la dirección de extrusión de la película de PVC 12 y ubicada espacialmente en los bordes externos de la bobina 1 1 . Estos bordes serán los que se plieguen para formar las aletas de selle del producto (cubo). El espacio libre de laca dejado en el centro de la bobina 1 1 (zona no sombreada de la figura 2) es un área importante para alojar el producto a empacar, que por ser un alimento no puede tener contacto con el recubrimiento. Adicionalmente permite que por condiciones de coeficiente de fricción, el caramelo no llegue a resbalar durante el empaque automático. The inner lacquer follows a pattern of continuous application, as can be seen in Figure 2 (shaded area), aligned with the extrusion direction of the PVC film 12 and located spatially at the outer edges of the coil 1 1. These edges will be those that fold to form the product's seal fins (cube). The lacquer free space left in the center of the coil 1 1 (non-shaded area of Figure 2) is an important area to house the product to be packaged, which, because it is a food, cannot have contact with the coating. Additionally it allows that due to friction coefficient conditions, the candy does not slip during automatic packing.
El ancho de grabación de las dos franjas continuas de lacas viene calculado especialmente para la longitud de las aletas de selle, y que puede ser por ejemplo de 13 milímetros. El ancho de la bobina 1 1 es de 46 milímetros, por ejemplo. The recording width of the two continuous strips of lacquers is calculated especially for the length of the seal fins, and which can be for example 13 millimeters. The width of the coil 1 1 is 46 millimeters, for example.
La laca exterior es el recubrimiento más importante para el desempeño del producto. A diferencia de la laca interior, la geometría de rombos continuos y alineados por el vértice, cubre toda el área de la bobina 1 (figura 3). La zona coloreada es la que identifica la presencia de la laca, la zona no sombreada está libre de laca. Esta configuración garantiza que la fuerza de sellado que se desarrolla alcanza un nivel perfecto para asegurar la hermeticidad con fácil apertura del producto en el momento del consumo. External lacquer is the most important coating for product performance. Unlike the inner lacquer, the geometry of continuous rhombuses and aligned by the vertex covers the entire area of coil 1 (Figure 3). The colored zone is the one that identifies the presence of the lacquer, the non-shaded zone is free of lacquer. This configuration ensures that the sealing force that develops reaches a perfect level to ensure tightness with easy opening of the product at the time of consumption.
En el diseño se destacan claramente dos cordones de rombos con una longitud por ejemplo de 6 milímetros entre bordes y un ángulo por ejemplo de 90 grados, con un espesor de pared de por ejemplo 1 milímetro. Esta hilera de rombos están ubicados 30 de manera simétrica del borde de la bobina y son un refuerzo de selle (figura 3). The design clearly highlights two rhombus cords with a length for example of 6 millimeters between edges and an angle for example of 90 degrees, with a wall thickness of for example 1 millimeter. This row of diamonds are located 30 symmetrically from the edge of the coil and are a seal reinforcement (figure 3).
Las hileras restantes, constituyen un enmallado de menor área de contacto, cuya distancia entre vértices alcanzan por ejemplo 4,2 milímetros y un ángulo por ejemplo de 74 grados con un espesor de pared de por ejemplo 0,5 milímetros. The remaining rows, constitute a mesh of smaller contact area, whose distance between vertices reaches for example 4.2 millimeters and an angle for example of 74 degrees with a wall thickness of for example 0.5 millimeters.
Un intervalo de ángulos utilizado habitualmente puede estar comprendido entre los 45 y 90 grados, pues es el intervalo en el que habitualmente se hacen los pliegues del empaque del caramelo. Un ángulo alterno de 74 grados es útil para llenar los espacios libres que deja la cuadricula a de 90 grados. A range of angles commonly used can be between 45 and 90 degrees, as it is the interval in which the folds of the caramel packing are usually made. An alternate angle of 74 degrees is useful for filling in the clearances left by the grid at 90 degrees.
El ancho total de una bobina 1 1 de alimento de una máquina empacadora (no siendo tal máquina objetos de la invención) es de por ejemplo 46 milímetros. El detalle de una configuración geométrica se puede observar en la figura 3, aunque en la realidad el recubrimiento de laca es totalmente transparente por lo que a simple vista podría pasar desapercibido. The total width of a food coil 1 1 of a packing machine (such machine not being objects of the invention) is for example 46 millimeters. The detail of a geometric configuration can be seen in Figure 3, although in reality the lacquer coating is totally transparent so that at first glance could go unnoticed.
