Title
(EN) MULTI-LAYER BAG WITH LOSS OF INTEGRITY MEANS OF DETECTION
(FR) SAC MULTICOUCHE AVEC MOYENS DE DÉTECTION DE PERTE D'INTÉGRITÉ
Abstract
(EN)
The invention relates to a multi-layer bag (2) comprising a porous portion (20) configured to allow a sterilizing gas to penetrate into the bag and a gas-impervious portion (21), characterized in that: the gas-impervious portion (21) comprises an outer layer (211), an inner layer (213) and an intermediate layer (212) integrally formed together so that the intermediate layer (212) is sealingly enclosed between the outer layer (211) and the inner layer (213) so as to be physically isolated from inner and outer environment of the bag, and the intermediate layer (212) comprises a matrix and at least one pigment distributed within the matrix, the pigment being configured to change at least one optical property in reaction to an environment change resulting from a damage of the outer and/or inner layer.
(FR)
L'invention concerne un sac multicouche (2) comprenant une partie poreuse (20) configurée pour permettre à un gaz stérilisant de pénétrer dans le sac et une partie imperméable au gaz (21), caractérisé en ce que : la partie imperméable aux gaz (21) comprend une couche externe (211), une couche interne (213) et une couche intermédiaire (212) formées d'un seul tenant ensemble de telle sorte que la couche intermédiaire (212) est enfermée hermétiquement entre la couche externe (211) et la couche interne (213) de façon à être physiquement isolée de l'environnement intérieur et extérieur du sac, et la couche intermédiaire (212) comprend une matrice et au moins un pigment distribué à l'intérieur de la matrice, le pigment étant configuré pour modifier au moins une propriété optique en réaction à un changement d'environnement résultant d'un endommagement de la couche externe et/ou interne.
