Abstract

Cette invention concerne un système d'emballage à atmosphère modifiée, ainsi que le procédé correspondant, qui sert à créer une atmosphère modifiée à l'intérieur d'un emballage (10) comportant un contenant interne (14) et un contenant externe (12). Ledit contenant interne (14) est composé au moins partiellement d'un matériau polymère sensiblement perméable à l'oxygène formant un plateau (16), alors que le contenant externe (12) est composé d'un matériau polymère sensiblement imperméable à l'oxygène. Après que l'on ait disposé à l'intérieur du contenant interne (14) un produit alimentaire du type viande crue (26), on purge ledit contenant interne avec un mélange approprié de gaz de façon à sensiblement évacuer l'oxygène dudit contenant interne (14). On ferme alors hermétiquement le contenant interne purgé (14) et on l'introduit à l'intérieur du contenant externe (12) sans fermer ce dernier hermétiquement. Puis on purge le contenant externe de façon à évacuer l'oxygène. Après avoir purgé le contenant externe (12), on ferme celui-ci hermétiquement. On dispose dans cet emballage (10) d'un désoxygénant (28) servant à absorber sensiblement tout oxygène résiduel à l'intérieur dudit emballage (10).
