Abstract

Packaging comprises polymer film (1) with portions of the film (1) sealed together to form an enclosure for the food stuff, said sealed portions being sealed by a film-to-film seal except in a vent region (5) where a lacquer layer (6) is bonded to each portion of film before said portions are sealed together with the lacquer layers cohering, the seal strength of the lacquer-to-lacquer interface (6) being similar to that of the film-to-film interface under predetermined storage conditions, and the seal strength of said lacquer-to-lacquer interface (6) being reduced compared with that of the film-to-film interface at temperatures above those expected under said predetermined storage conditions so that the enclosure is vented to atmosphere by a cohesive peel action in the vent region (5) between said lacquer layers (6).

Claims (10)

1. Envase para artículos alimenticios, destinado a ser calentado, que comprende una lámina de un polímero (1) con partes de la lámina fijadas entre sí, de forma estanca para constituir una envolvente para el producto alimenticio, estando estanqueizadas dichas partes mediante un cierre estanco de tipo elemento laminar a elemento laminar, excepto en una zona de ventilación (5), en la que una capa de laca (6) está unida a cada una de las partes laminares antes de que dichas partes sean unidas de forma estanca entre sí, cohesionándose dichas capas de laca, siendo la resistencia de estanqueidad del interfaz laca a laca similar al interfaz de un elemento laminar con un elemento laminar en condiciones de almacenamiento predeterminadas, y reduciéndose la resistencia de estanqueidad de dicho interfaz laca a laca en comparación con el del interfaz de elemento laminar a elemento laminar a temperaturas superiores a las esperadas bajo dichas condiciones de almacenamiento predeterminadas, de manera que la envolvente es ventilada a la atmósfera por una acción de pelado en la zona de ventilación (5) entre dichas capas de laca (6).1. Container for food items, intended to be heated, comprising a sheet of a polymer (1) with parts of the sheet fixed to each other, tightly to constitute an envelope for the food product, being said parts sealed by a sealed type closure laminar element to laminar element, except in an area of ventilation (5), in which a layer of lacquer (6) is attached to each one of the laminar parts before said parts are joined tightly with each other, these layers of lacquer coalescing, the sealing resistance of the lacquer to lacquer interface similar to the interface of a laminar element with a laminar element under predetermined storage conditions, and reducing the sealing resistance of said lacquer to lacquer interface in comparison with the laminar element to element interface laminate at temperatures above those expected under these predetermined storage conditions, so that the envelope is vented to the atmosphere by a peeling action on the ventilation zone (5) between said lacquer layers (6). 2. Envase, según la reivindicación 1, en el que dicha envolvente es formada al cerrar de forma estanca partes del elemento laminar (1) entre sí a lo largo de múltiples costuras (2, 3, 4) con una zona de ventilación (5) formada en una o varias costuras (4).2. Container according to claim 1, wherein said envelope is formed by sealing parts of the seal laminar element (1) with each other along multiple seams (2, 3, 4) with a ventilation zone (5) formed in one or several seams (4). 3. Envase, según la reivindicación 2, en el que dicha envolvente está formada al unir de forma estanca partes del elemento laminar entre sí a lo largo de múltiples costuras (2, 3, 4) con dicha zona de ventilación (5) formada a lo largo de la totalidad de una costura (4), pero no a lo largo de la totalidad de la longitud de todas las costuras (2, 3).3. Package according to claim 2, wherein said envelope is formed by tightly joining parts of the laminar element with each other along multiple seams (2, 3, 4) with said ventilation zone (5) formed along the all of a seam (4), but not throughout the entire the length of all seams (2, 3). 4. Envase, según cualquiera de las reivindicaciones anteriores, en el que la laca (6) es aplicada al elemento laminar por un proceso de impresión de huecograbado o flexografía.4. Packaging, according to any of the previous claims, wherein the lacquer (6) is applied to the laminar element by a gravure printing process or flexography 5. Envase, según cualquiera de las reivindicaciones anteriores, en el que el elemento laminar (1) comprende polipropileno, polietileno, poliéster, poliamida, celulosa regenerada, ácido poliláctico, o una combinación de cualesquiera de los anteriores.5. Packaging, according to any of the previous claims, wherein the laminar element (1) It comprises polypropylene, polyethylene, polyester, polyamide, regenerated cellulose, polylactic acid, or a combination of any of the above. 6. Envase, según la reivindicación 5, en el que la laca (6) comprende una resina basada en EVA.6. Container according to claim 5, wherein The lacquer (6) comprises an EVA based resin. 7. Envase, según la reivindicación 6, en el que la laca (6) comprende una combinación de disolventes que comprende alcoholes, ésteres e hidrocarburos.7. Package according to claim 6, wherein The lacquer (6) comprises a combination of solvents comprising alcohols, esters and hydrocarbons. 8. Envase, según cualquiera de las reivindicaciones 1 a 5, en el que la laca (6) comprende una laca EVA basada en agua o una laca basada en un disolvente epoxi/acrílico.8. Packaging, according to any of the claims 1 to 5, wherein the lacquer (6) comprises an EVA lacquer water based or a solvent based lacquer epoxy / acrylic. 9. Envase, según cualquiera de las reivindicaciones anteriores, en el que el elemento laminar (1) está dotado de microperforaciones para soportar una atmósfera modificada dentro del envase cuando contiene un artículo alimenticio que requiere respiración.9. Packaging, according to any of the previous claims, wherein the laminar element (1) is equipped with microperforations to withstand a modified atmosphere inside the package when it contains a food item that It requires breathing. 10. Elemento laminar para la producción de un envase, según cualquiera de las reivindicaciones 1 a 9, en el que como mínimo una zona del elemento laminar (1) adaptada para su incorporación en un cierre de estanqueidad del envase entre dos partes del elemento laminar, está dotada de un recubrimiento de una laca (6) que comprende una resina basada en EVA.10. Laminar element for the production of a package according to any one of claims 1 to 9, wherein at least one area of the laminar element (1) adapted for its incorporation in a seal of the container between two parts of the laminar element, is provided with a coating of a lacquer (6) comprising an EVA based resin.
