Abstract

Procédé de détection de ruptures dans les joints thermiques d'emballages stérilisables et emballages réalisés selon ce procédé. L'emballage est caractérisé par le fait qu'il comprend un stratifié 12 en matière plastique transparent constitué d'un polyester et d'une matière thermoplastique pouvant être soudée par chauffage, ce stratifié étant soudé thermiquement par ses bords sur une feuille de papier kraft 10 de qualité chirurgicale teinte en une couleur foncee, suffisamment poreuse pour permettre la stérilisation par gaz ou vapeur d'eau, mais imperméable aux bactéries, de manière telle que, lors d'une rupture de la jonction réalisée par soudure, cet élément en matière plastique, initialement transparent, prenne un aspect translucide dans la zone de rupture, ce qui provoque un contraste très net de couleur entre la partie rompue de la soudure et d'une part la couleur foncée du papier, d'autre part le restant de la zone de soudure. Application aux instruments chirurgicaux.Method for detecting breaks in the thermal seals of sterilizable packaging and packaging produced according to this method. The packaging is characterized by the fact that it comprises a laminate 12 of transparent plastic material consisting of a polyester and a thermoplastic material which can be welded by heating, this laminate being heat welded by its edges on a sheet of kraft paper. 10 surgical grade dyed to a dark color, sufficiently porous to allow sterilization by gas or steam, but impermeable to bacteria, such that, upon rupture of the joint made by welding, this material element plastic, initially transparent, takes on a translucent appearance in the rupture zone, which causes a very clear contrast in color between the broken part of the weld and on the one hand the dark color of the paper, on the other hand the rest of the weld area. Application to surgical instruments.
