Title (EN) MICROPOROUS MATERIAL AND A HEAT-SEAL ABLE BAG PREPARED THEREOF
(FR) MATERIAU MICRO-POREUX ET SACHET SCELLE A LA CHALEUR PREPARE AVEC CE MATERIAU
Abstract: front page image
(EN)A bag, one side of which consists of a gas impenetrable, transparent material and the other side consists of a microporous paper or similar sheet material prepared from fibres, the one side of which has been coated with a layer of a coating composition in the form of a viscous slurry of a micronized powderous water-insoluble material, preferably talcum, in an aqueous suspension of a thickening agent such as carboxy methyl cellulose for control of the pore size of the paper and for binding fibres in the paper surface when the bag is manufactured by heat-sealing both materials against each other. The finished bag containing an instrument or a product is sterilized by heat while air in the bag can penetrate out through the pores of the paper, the pore size being such that microorganisms cannot penetrate into the bag. The bag can be opened by tearing the heat-sealing without any liberation of fibres from the paper; the invention includes the microporous sheet material coated with the coating composition.
(FR)Sachet, dont un cote consiste en un materiau transparent impermeable aux gaz et l"autre cote consiste en du papier micro-poreux ou materiau en feuille similaire prepare a partir de fibres, le premier cote ayant ete revetu d"une couche d"une composition de revetement sous forme de boue visqueuse d"un materiau poudreux microscopique insoluble dans l"eau, de preference du talc, dans une suspension aqueuse d"un agent d"epaississement tel que de la methloycarboxycellulose pour controler la dimension des pores du papier et pour lier les fibres a la surface du papier lorsque le sachet est fabrique par scellement thermique des deux materiaux l"un contre l"autre. Le sachet fini contenant un instrument ou un produit est sterilise par la chaleur tandis que de l"air contenu dans le sachet peut s"echapper au travers des pores du papier, la dimension des pores etant telle que des micro organismes ne peuvent penetrer dans le sachet. Le sachet peut etre ouvert en dechirant la jointure thermique sans liberer les fibres du papier; l"invention comprendre materiau en feuille micro-poreux revetu de la composition de revetement.
