Title (EN) VACUUM PACKAGING FILMS PATTERNED WITH PROTRUDING CAVERNOUS STRUCTURES
(FR) FILMS D'EMBALLAGE SOUS VIDE A STRUCTURES CAVERNEUSES PROTUBERANTES
Abstract: front page image
(EN)The present invention teaches a film having a pattern of protruding structures. When used in the vacuum packaging bag material context, the result is a vacuum packaging bag that a consumer can effectively evacuate and hermetically seal. The protruding structures tend to form channels that enable gas to evacuate from within a vacuum packaging bag. In certain embodiments, the protruding structures are formed only on an inner side of the vacuum packaging film, typically through a hot casting or heat-extrusion process. As a result, far less bag material is required than in the prior art patterned film formed through cold embossing processes. The present invention also contemplates a variety of applications for the films, including preformed bags and bag rolls, as well as a variety of apparatus for manufacturing the films and appliances for utilizing the bags and bag rolls.
(FR)L'invention concerne un film à structures protubérantes. En cas d'application au contexte de sac d'emballage sous vide, le résultat donne un produit à évacuation et fermeture hermétique efficaces. Les structures considérées tendent à former des canaux permettant l'évacuation de gaz depuis un tel sac. Selon certaines variantes, elles sont formées seulement sur un côté interne du film, généralement par coulée à chaud ou extrusion à chaud. On utilise ainsi beaucoup moins de matériau de sac qu'avec la technique classique de gaufrage à froid. L'invention concerne aussi diverses aplpications pour les films en question, y compris les sacs et rouleaux de sacs préformés, et divers appareils de fabrication de films et dispositifs d'utilisation des sacs et rouleaux de sacs.
