Abstract

Le sac refermable (100) a un corps principal (102) comprenant une couche d'étanchéité (150). Le sac refermable (100) peut être positionné de manière sélective entre une position ouverte, non scellée et une position fermée, scellée. Lorsque le sac refermable (100) est dans la position fermée, scellée, la couche d'étanchéité (150) se présente sous une forme déformée. De manière avantageuse, le sac refermable (100) peut être enroulé et scellé de manière répétée, et déroulé et non scellé, comme souhaité sans utilisation de mécanismes d'étanchéité intégrés ou non intégrés supplémentaires.
