てしまうという欠点があった。Problems to be Solved by the Invention In this conventional antibacterial sheet, the antibacterial zeolite particles are present almost uniformly in the synthetic resin sheet or the film layer (hereinafter simply referred to as a sheet), so that a considerable amount of the antibacterial agent is present. Even an antibacterial sheet containing zeolite particles has an extremely small amount of antibacterial zeolite particles on the surface that comes into contact with the antibacterial substance (such as food), and the antibacterial zeolite particles inside the sheet cannot exert an antibacterial effect. Therefore, there is a drawback that the antibacterial action is too small for the amount of the antibacterial zeolite particles contained in the sheet, and the antibacterial zeolite particles are expensive when a large amount of the antibacterial zeolite particles is contained in the sheet. Therefore, the antibacterial action is good, but there is a drawback that the antibacterial sheet becomes expensive.

て種々使用されている。Means for Solving the Problems This invention uses zeolite particles having antibacterial properties, and this zeolite is obtained by substituting a part of the aluminosilicate salt forming ions with metal ions of silver, copper and zinc. It is said that the substituted metal ions, particularly silver ions, have an antibacterial property that hinders the activity of bacteria (microorganisms) by the action of the silver ions, and in general, silver ions have been variously used since ancient times as having an antibacterial property.

使用量が少ないために抗菌性シートが安価である。Action The antibacterial sheet of the present invention is such that the antibacterial zeolite particles are fixed to only one surface layer of one side of the synthetic resin sheet such that one part of the antibacterial zeolite particles protrudes from the one side surface layer. Since the base material of a simple substance or a laminated body such as an aluminum alloy foil is provided on the other side surface of the sheet, one side surface of the antibacterial sheet has a particularly large antibacterial action and a small amount of antibacterial zeolite particles has an antibacterial action. It is fully demonstrated. Moreover, since the amount of antibacterial zeolite particles used is small, the antibacterial sheet is inexpensive.

に固着した抗菌性シートを造る方法がある。There are various ways to make the antibacterial sheet 4, but as an example, a coating machine is applied to the front side of a metal foil such as an aluminum alloy foil, an aluminum foil, a stainless foil, a titanium foil, an iron foil, a tin foil having a thickness of about 10 μm to 20 μm. Applying a molten synthetic resin solution that also functions as an adhesive to a thickness of 5 μm to 30 μm, the synthetic resin solution does not completely solidify and the particle size is about 0.7 μm to 1.2 μm when it is in a semi-dried state. By sprinkling the zeolite particles on the front surface at a rate of 10 mg / m 2 position from above,
There is a method in which an antibacterial zeolite particle is formed while a synthetic resin sheet is formed and antibacterial zeolite particles are present only in the front surface layer of the synthetic resin sheet, and one part of the antibacterial zeolite particle is fixed in a state of protruding to the front side. .

The difference from the above embodiment is that an aluminum alloy foil 13 'and an aluminum alloy foil 13' are used as the base material 13 in the synthetic resin 1
This is because the base material 13 bonded by 3 ″ was used.
The back side of the synthetic resin sheet 11 is adhered to the front side of 3 and laminated,
Further, the antibacterial sheet 14 is obtained by fixing a predetermined amount of the antibacterial zeolite particles 12 only on the front surface layer of the synthetic resin sheet 11 such that one part of the antibacterial zeolite particles 12 is projected to the front side.

きる。Effect of the Invention The antibacterial sheet of the present invention has the antibacterial zeolite particles fixed to only one surface layer of one side of the synthetic resin sheet in such a state that one part of the antibacterial zeolite particles protrudes from the one surface layer. Since a laminated body is formed by providing a base material made of metal foil or the like on the other side surface of the synthetic resin sheet, the antibacterial zeolite particles protruding from the surface are directly contacted with the antibacterial substance such as food and the surface layer is often used. Since the above antibacterial zeolite particles are present, a very large antibacterial action can be exerted relative to the amount of the antibacterial zeolite particles used. And even though a small amount of expensive antibacterial zeolite particles was used for only one surface layer of the synthetic resin sheet, antibacterial zeolite particles protruding from the surface were directly contacted with the antibacterial substance such as food, and many surface layers were used. Due to the presence of the antibacterial zeolite particles, the antibacterial effect can be sufficiently exerted and the cost of the antibacterial sheet can be reduced.
