ロピレン積層フイルムが一般に用いられていた。 Conventionally, articles such as reusable medical instruments used in hospitals and the like have been cleaned, wrapped, and subjected to steam sterilization or ethylene oxide gas sterilization after being used in surgeries and the like. The envelope used at this time was so-called "sterile paper," which is a specially made paper that has better sterilization properties and bacteria-blocking properties than ordinary paper. This sterilized paper can be used alone to wrap sheets, etc., or as a bag-like sterilized bag, items to be sterilized, such as surgical scissors, are placed in the sterilized bag, sealed, and sterilized for use in the next surgery. They were kept for a certain period of time before being used. In this case, if such a sterilization bag is made only of paper, it is not possible to directly see the items to be sterilized inside the bag, so one side of the bag is made of paper and the other side is made of heat-resistant resin layer and heated. A transparent film laminated with a fusible resin layer was used. Such a transparent laminated film is, for example, a dry laminated film in which the heat-resistant resin layer is a biaxially stretched polyester film and the heat-fusible resin layer is an ethylene-propylene copolymer film or a simple polypropylene film. was often used. Note that the heat-resistant resin layer may be a stretched polyamide film (nylon film), and the heat-fusible resin layer may be a polyethylene film. However, in the case of steam sterilization, due to the sterilization temperature, 120℃ or
Polyester/polypropylene laminated films that withstand sterilization temperatures of 130°C were commonly used.

た。 When heat-sealing this polyester/polypropylene laminated film and paper to make a bag or a cylindrical roll, the heat-sealing temperature must be raised to 230°C or higher, otherwise the adhesion will be poor, and it may not be used in hospitals, etc. If the adhesive was not sufficiently adhered with an impulse seal or the like, it would peel off during steam sterilization. For this purpose, paper is coated with a heat sealing agent, or ethylene-propylene copolymer or polypropylene fibers are cut into 2 to 3 mm pieces, and 5 to 20% of these short fibers are blended with pulp and then mixed and sealed. It was used to increase the strength. However, coating paper with a heat sealant is undesirable because it can cause the paper to adhere to the objects to be sterilized during steam sterilization.In addition, paper made by blending short fibers such as polypropylene copolymer with pulp is All of the conventional products had drawbacks, such as poor properties, poor suitability for printing such as gravure printing, and poor commercial value.

ある。 The sterilization bag of the present invention for the above purpose is an envelope-shaped bag with one side made of a laminated film made of a heat-fusible resin layer and a heat-resistant resin layer, and the other side made of paper. The heat-fusible resin layer on one side is arranged so as to be in contact with the paper on the other side,
In the bag formed by heat-sealing the periphery, the heat-fusible resin layer is made of a modified polypropylene layer. In the above, preferably, the modified polypropylene layer is modified with an unsaturated carboxylic acid or its anhydride and has a modifier concentration of 0.01 to 10% by weight, or the modified polypropylene layer is a modified polypropylene layer containing 50 to 80% of the modified polypropylene in polypropylene.
It is best to use a mixture of % by weight. In the sterilization bag according to the present invention, good sealing strength can be obtained in normal heat sealing operations, and the heat-fusible resin layer can be used to seal the sterilized material inside the bag at a steam sterilization temperature of 120 to 130°C. It does not adhere to objects and overcomes the drawbacks of the prior art.

した。 The sterilization bag in this example has a heat-resistant resin layer 2
A biaxially stretched polyester film with a thickness of 12 μm was used as the film, an isocyanate adhesive was coated thereon as the anchoring agent layer 3, and a modified polypropylene layer 1, which was a heat-fusible resin layer, was coated on top of the isocyanate adhesive. Admar QF-500 (product name) manufactured by Co., Ltd. is 30μ
A laminated film coated with extrusion to a thickness of 1 was used as film 4 on one side. As the paper 5 on the other side, 60 g/m 2 Kraft sterilized paper manufactured by Tokai Pulp Co., Ltd. was used. These are cut into rectangles and placed so that the Admer layer, which is the modified polypropylene layer 1 of the laminated film 4, is in contact with the kraft sterilized paper 5, and the peripheral heat-sealed portion 6
was heat-sealed, and the folded gauze 7 to be sterilized was housed therein. The heat sealing conditions are
200℃, 1 second, 0.7Kg/cm 2 (10bs/in 2 ),
A bag with a seal width of 10 mm, a bag width of 100 mm, and a bag length of 200 mm was manufactured.
