フィルムが提案されている。(Prior art) Attempts have been made to impart antibacterial properties to resin films used for food packaging, etc. For example, organic disinfectants such as diphenyl ether disinfectants and chlorhequindin disinfectants have been used. Mixed resin films and resin films mixed with inorganic antibacterial agents such as silver ion-containing zeolite particles have been proposed.
ところが有機系殺菌剤を混入した樹脂フィルムはその殺

フィルムを完成して提出した。Therefore, the applicant of the present application previously filed a patent application No. 1-124760 in which a powder of soluble glass containing silver ions of 0.05 to 1' and 0% by weight expressed as Ag2O was prepared at a ratio of 0.1 to 15% by weight. We completed and submitted a resin film with antibacterial properties characterized by dispersion.

量を増加させて、本願発明を完成させた。However, in the technical content of Japanese Patent Application No. 1-124760, since the amount of silver contained in the soluble glass is small, it is necessary to increase the amount of soluble glass added to the resin film. Therefore, in order to reduce costs and improve antibacterial properties, the composition and melting conditions of the soluble glass were changed to increase the amount of silver contained in the soluble glass. Completed the invention.

る。(Problems to be Solved by the Invention) The present invention solves the above-mentioned problem, that is, since the amount of silver contained in soluble glass is small, it is possible to strengthen the antibacterial pile machine action and to solve the problems described above. If you want to maintain the mechanism, a large amount of soluble glass must be used, and for this reason,
It is a non-leaching additive that solves the problem of resin film losing its properties and can maintain stable antibacterial effects over a long period of time.It is also easy to manufacture and is compliant with the Food Sanitation Act. This was completed in order to provide a resin film with excellent safety, antibacterial and anti-fungal properties that can control the amount of silver ions eluted within the range of .

特徴とする樹脂フィルム関するものである。(Means for Solving the Problems) In order to solve the above problems, the present invention provides silver ions to Ag2
The present invention relates to a resin film characterized in that meltable glass powder containing 1.0 to 6.5% by weight expressed as O is dispersed at a ratio of 0.01 to 15% by weight.

杭機作用を発揮させる。As described above, in the present invention, the content of silver ions in the soluble glass, which allows silver ions to be eluted at a constant rate, is increased by increasing the oxidation tendency of the batch for melting soluble glass and by controlling the melting atmosphere. The soluble glass powder, which is increased by making it strongly oxidizing, is dispersed in the resin film to exhibit antibacterial pile action.

することとなる。This meltable glass is a general term for glasses whose composition has been adjusted by considering the physical and chemical properties of the glass so that it has a controlled dissolution rate. Silver ions can be eluted at a fixed rate over any period of time over several years. The eluted silver ions then adsorb to the cell walls of bacteria and microorganisms or concentrate within their cell membranes, inhibiting the growth of bacteria and microorganisms through the so-called oligocynamy action, and exhibiting an antibacterial pile effect.
本発明においては、このような銀イオンをＡｇ２Ｏ表示

．５％を越えると溶解性ガラスを溶解する際に、如何に
酸化性を強くして溶融しても、錫金属が析出し、硝子化
出来ないからである。In the present invention, a soluble glass powder containing 1.0 to 6.5% by weight of such silver ions expressed as Ag2O is used. Here, the content of silver ions is less than 1.0%, which is currently being applied for in the earlier application, Japanese Patent Application No. 1-124760.
．． This is because if it exceeds 5%, no matter how strong the oxidizing properties are when melting the soluble glass, tin metal will precipitate and glass cannot be formed.

、成形性等が損なわれるためである。粒径が１μｍ未満
となると溶解性ガラスの粉砕や分級の効率が極端に低下
するので製造上好ましくない。Note that the soluble glass is preferably used with a particle size of 50 μm or less, more preferably about 1 to 25 μm. This is because if the particle size is too large, uniform dispersion into the resin film becomes difficult and the inherent transparency, mechanical strength, moldability, etc. of the resin film are impaired. If the particle size is less than 1 μm, the efficiency of crushing and classifying the soluble glass will be extremely reduced, which is not preferable in terms of production.

のものがこれに該当するものと解される。Further, the amount of soluble glass mixed into the resin film varies depending on the purpose of use, and is 0.01 to 15% by weight. This is because if it is less than 0.01%, the antibacterial pile effect will be insufficient, and if it exceeds 15%, the above-mentioned properties of the resin film will be lost. In this way, the present invention exhibits a sufficient antibacterial pile effect by controlling the amount of soluble glass mixed in and the content of silver ions, but it also meets the safety standards for non-leaching additives under the Food Sanitation Act. Only a trace amount of silver ion was eluted, which was satisfactory. Here, non-eluting additives under the Food Sanitation Act refer to additives in which no eluate is detected even if elution operations and elution amount measurements are performed in accordance with the Food Sanitation Act, and in the case of silver ions, 50μg It is understood that those with an elution amount of 1/1 or less fall under this category.

オンを溶出させるものとする。(Function) Such a resin film of the present invention is used for food packaging, etc., and moisture permeates into the interior due to the slight water permeability and moisture permeability of the resin, and this moisture causes a trace amount of soluble glass to be absorbed. The silver ions, which have antibacterial and antifungal properties, are eluted. The amount of silver ions cannot be detected by normal analytical methods and is not a problem under the Food Sanitation Act, but the amount is sufficient for antibacterial action. The minimum amount of silver ions that can exert antibacterial action is 10μg/l.
According to the Food Sanitation Law, as mentioned above, the silver ion content is preferably 50 μg/l or less, so silver ions are eluted in an amount intermediate between these two values.
