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).
La présente invention concerne un conditionnement qui comprend un film polymère (1), des parties du film (1) étant scellées les unes aux autres pour former une enceinte pour aliments, lesdites parties scellées étant scellées par un scellage de film à film sauf dans une région d'aération (5) où une couche de vernis (6) est collée sur chaque partie de film avant que lesdites parties ne soient scellées les unes aux autres avec les couches de vernis adhérentes, la résistance au scellage de l'interface de vernis à vernis (6) étant similaire à celle de l'interface de film à film dans des conditions de stockage prédéterminées et la résistance au scellage de l'interface de vernis à vernis (6) étant réduite par rapport à celle de l'interface de film à film à des températures au-dessus de celles prévues dans lesdites conditions de stockage prédéterminées de sorte que l'enceinte soit aérée en contact avec l'atmosphère par une action de décollage cohésive dans la région d'aération (5) entre lesdites couches de vernis (6).
