Abstract

Pressed regions (3) of the sheet (1) are left clear of the anti-adherent silicone coating.

Description

[0001] La invención se refiere a un procedimiento para fabricar una lámina de plástico con un revestimiento antiadherente, en particular silicona, y a un procedimiento para fabricar un envoltorio con tiras de cierre marginal estampadas a partir de una porción de la lámina de plástico. [0001] The invention relates to a process for manufacturing a plastic sheet with a non-stick coating, in particular silicone, and to a process for manufacturing a wrap with marginal closure strips stamped from a portion of the plastic sheet.

[0002] Ya se conocen envoltorios de este tipo y las láminas plásticas correspondientes, pero todos ellos tienen como desventaja que las tiras de cierre estampadas sólo pueden fabricarse con mucha dificultad y con procedimientos especiales, en la mayoría de los casos un costoso procedimiento de agujas. [0002] Wrappers of this type and the corresponding plastic sheets are already known, but all of them have a disadvantage that stamped closure strips can only be manufactured with great difficulty and with special procedures, in most cases an expensive needle procedure .

[0003] Por ejemplo, el documento US 5333493 da a conocer una lámina de embalaje similar que presenta zonas parciales cubiertas con un revestimiento antiadherente. [0003] For example, US 5333493 discloses a similar packaging sheet having partial areas covered with a non-stick coating.

[0004] El documento US-A-5033250 da a conocer el uso de marcas repetitivas para controlar una máquina envasadora en lo que respecta al comportamiento de dilatación de la envoltura a procesar, a la velocidad, etc. [0004] US-A-5033250 discloses the use of repetitive marks to control a packaging machine with regard to the expansion behavior of the envelope to be processed, at speed, etc.

[0005] La invención tiene por objetivo proponer un procedimiento para fabricar una lámina de plástico y un procedimiento para fabricar envoltorios a partir de dicha lámina de plástico, en el que las tiras no cubiertas por el revestimiento antiadherente se posicionen con tal exactitud que haga posible una disposición en dos bordes opuestos de una porción respectivamente, y en el que el envoltorio fabricado pueda cerrarse de forma segura y que además sea duradero. [0005] The aim of the invention is to propose a process for manufacturing a plastic sheet and a method for manufacturing wrappers from said plastic sheet, in which the strips not covered by the non-stick coating are positioned with such accuracy that it makes possible an arrangement on two opposite edges of a portion respectively, and in which the manufactured wrapper can be closed securely and also be durable.

[0006] Este objetivo se alcanza según la invención dejando desprovistas de revestimiento antiadherente zonas parciales de las porciones de la lámina en las que está previsto el estampado, estando previstas marcas distanciadas que se definen para controlar el revestimiento con agente antiadherente en la lámina, uniéndose mutuamente al menos dos zonas parciales de la porción de lámina desprovistas de revestimiento antiadherente, disponiéndose las zonas desprovistas del revestimiento antiadherente en una dirección esencialmente transversal a la dirección de transporte de la lámina aún sin dividir en porciones, y estando realizada la unión de las zonas parciales en forma de un, así llamado, corrugado en el que están previstos numerosos estampados individuales en forma de línea. [0006] This objective is achieved according to the invention, leaving partial areas devoid of the non-stick coating part of the portions of the sheet in which the printing is provided, with spaced marks being defined to control the coating with non-stick agent in the sheet being provided, joining mutually at least two partial zones of the sheet portion devoid of non-stick coating, the areas devoid of the nonstick coating being disposed in an essentially transverse direction to the direction of transport of the sheet even without dividing into portions, and the joining of the zones being performed partial in the form of a, so-called, corrugated in which numerous individual patterns in the form of a line are provided.

[0007] De este modo, en la zona desprovista de revestimiento antiadherente se puede colocar una tira de cierre estampada y pueden realizarse fácilmente de forma continua porciones de lámina para envoltorios. Además es posible un control muy preciso de las superficies de la lámina con revestimiento antiadherente y las desprovistas del mismo. [0007] Thus, in the area devoid of non-stick coating, a stamped closure strip can be placed and portions of wrapping foil can be easily made continuously. In addition, very precise control of the surfaces of the non-stick coated sheet and those without it is possible.

[0008] De este modo se garantiza un cierre mejorado y más seguro del envoltorio. [0008] This ensures an improved and safer closure of the package.

[0009] También se asegura el mantenimiento de la unión mutua de las zonas parciales. [0009] The maintenance of the mutual union of the partial zones is also ensured.

[0010] Más allá de la invención, la unión de las zonas parciales puede estar realizada como un sellado adicional. [0010] Beyond the invention, the joining of the partial zones can be carried out as an additional seal.

[0011] De este modo, en caso de láminas susceptibles de sellado se puede realizar una unión segura de las zonas parciales entre sí. [0011] In this way, in the case of sheets that can be sealed, a secure connection of the partial zones to each other can be made.

[0012] La invención se ilustra en los dibujos mediante un ejemplo de realización. En los dibujos: [0012] The invention is illustrated in the drawings by an exemplary embodiment. In the drawings:

La figura 1 muestra una lámina continua para fabricar un envoltorio y Figure 1 shows a continuous sheet for manufacturing a wrapper and

la figura 2 muestra un envoltorio producido con una porción de lámina. Figure 2 shows a wrapper produced with a sheet portion.

[0013] La figura 1 muestra una lámina continua 1 que presenta un revestimiento antiadherente de silicona en zonas parciales 2. Otras zonas parciales 3, que se encuentran entre las zonas parciales 2, están desprovistas de dicho tratamiento con silicona. En la lámina continua 1 están previstas marcas de referencia 4 para control y posicionamiento durante la aplicación del tratamiento con silicona en las primeras zonas parciales 2 de la lámina continua 1. [0013] Figure 1 shows a continuous sheet 1 having a non-stick silicone coating in partial zones 2. Other partial zones 3, which are between the partial zones 2, are devoid of said silicone treatment. In the continuous sheet 1 reference marks 4 are provided for control and positioning during the application of the silicone treatment in the first partial zones 2 of the continuous sheet 1.

[0014] Para formar un envoltorio 10, la lámina continua 1 se corta a lo largo de las líneas 5. Las porciones 6 resultantes se utilizan para envolver un objeto 11 a envasar y las capas superpuestas de las porciones 6 se corrugan entre sí en las zonas desprovistas de revestimiento antiadherente 3. [0014] To form a wrapper 10, the continuous sheet 1 is cut along the lines 5. The resulting portions 6 are used to wrap an object 11 to be packaged and the superimposed layers of the portions 6 are corrugated together in the areas devoid of non-stick coating 3.

[0015] Este corrugado 12 está constituido por estampados individuales en forma de línea que agarran las dos capas uniéndolas mutuamente. [0015] This corrugated 12 is constituted by line-shaped individual prints that grip the two layers by joining them together.
