V. Description of the invention (2) __ However, even if it is applied on the surface of the paper ^ The coating film can impart water resistance to the surface of the paper ^^ The coating film of synthetic resin grease has no deodorizing function or enoic acid type Synthetic tree bentonium is put into different kinds of food at the same time: And, the phenomenon of taste transfer between each other occurs, so that the taste of food is reduced. , Genkou mouth mouth quality or original In addition, because it does not have a humidity control function, because of &, it will make other foods damp due to the water produced: Genkou mouth / melon is low, at the same time, it is stored in Fresh foods are in the shape of ^; = = or the taste decreases, which causes the problem of reduced freshness. ", In addition, within the knowing time, because the conventional wrapping paper is only simple or even if it is packed with food or fresh food: two * function or humidity control function. Let's ... The subject of the present invention is to provide a "wet" packaging paper for storage or packaging of food or fresh food by providing functions to paper materials of wrapping paper or paper containers, and to "solve the problem" in order to solve As mentioned above, the invention of the patent application of the present invention adopts the structure described below: The first layer is coated with carbon powder on the surface of the packaging paper, and the carbon coating is provided for the patent application. In the invention of the scope item 1, the structure described below is adopted

Description of the invention (4) In addition, as another embodiment, in addition to the formed paper container, Examples include paper bags made from box-making operations using =, or packaging paper or tissue paper as packaging materials.

m Dun layer 2, based on the weight ratio of AO parts of the acrylic quarter machine, mixed into about 200 microns, 1% into the resin, and it is coated with a thickness of 0.05 ππη Γ coating number acrylic closed, so that于 Forming a carbon coating layer 2. In addition, in the state of paper loading on the surface of the paper, the carbon coating layer of the bag or package on one surface of the paper. ▲ Apply the same charcoal used in the formation of the carbon coating layer 2 described above. If you say f and use it, the powder 2a is used to make your mouth a little bit, and the carbon content is 95. Binchotan charcoal with the highest grade of more than 5% (powder in charcoal of 5% or more and powder of about 2.0 microns is used. The two can be made by crushing and processing binchotan charcoal; it is used in the preparation of binchotan (charcoal also You can directly cut and process the 4 kinds of wormwood (lt) and cut them into processed cutting powders, and recycle the cutting worms that were originally discarded products for recycling. 卞 刀 刀 叔叔In addition, in order to form the carbon coating layer 2 of the paper material 3, a conventional coating means such as a roller is used to form a dazzling melt: :: a mixture of 1 tree moon and carbon powder 23, The coating thickness is as follows: The coating thickness is' from the size of the carbon powder 2 & and the thickness is up to 0.05 mm. At the same time, the aforementioned enoic acid-based grease is, for example, acrylic Addition of σ-alcohol-based solvents to acid-styrene copolymers

585819 _Case No. 8911194 · ?. Amendment Fifth, the description of the invention (5) agent, water, and a small amount of additives, in addition, the acrylic synthetic resin can perform the functions described below: On the surface of paper 3 An adhesive function for adhering the carbon powder 2a; and a function of imparting reinforcement and water resistance to the paper material 3. f Here, 'If the carbon powder 2a uses a carbon powder of about 200 micrometers or more, the carbon particles become larger' so that the surface of the carbon coating layer 2 becomes a rough surface with unevenness, so that the value of the product is reduced, and at the same time, the When the mixing amount of the carbon powder 2a to the acrylic synthetic resin greatly exceeds the ratio of 3 to 1, the mixing amount of the carbon powder 2a becomes too much, so that the carbon powder layer 2 peels off from the carbon coating layer 2. At the same time, when the mixing ratio of the carbon powder 2a to the acrylic synthetic resin is substantially less than the ratio of 3 to 1, the mixing amount of the carbon powder 2a becomes too small, so that the effective function of reducing carbon . _In addition, when the coating thickness of the 5 coating layer 2 is Q · Q 5 mm or more, cracks may be generated in the slave coating layer 2, so it is not ideal. The paper container of the present invention has a structure as described above. Therefore, the packaging paper or paper container 1 is used for storage, packaging, and packing of various foods or fresh foods, for example. The carbon coating layer 2 coated on the inner surface of the aforementioned paper container 1 is provided with good deodorizing, humidity-controlling, and gas-adsorbing functions, and the carbon coating layer 2 ′ even contacts food directly, It also has good security. Fig. 3 'shows the results of experiments confirming the deodorizing effect of the carbon coating layer. ° The above κ test is a test piece coated with a carbon coating on the surface of a thick paper

The correction is to make only a test piece composed of uncoated paper that is a simple thick paper, and to cut one of the two test pieces of the same size and put them in, and sample each t 溥In the device, then, in each of the sheet samplers: tritium hydrogen gas, so that the internal pressure becomes atmospheric pressure, and by using the gas and dioxin method, the sulfur disulfide is measured within a predetermined time each time. The test piece coated with the broken coating layer is 3 parts by weight with respect to propylene = ^ and resin, mixed with about 200 micrometers in a weight ratio of 1 part; And it is 0.05 mm thick: on the surface of the paper material to facilitate the formation of a carbon coating layer. The result of the experiment that is not = ... It is quite clear that the value of _ is relatively low compared to the time that has passed, and = has a better deodorizing effect. Wei Uk then produced a paper container coated with the same paper as the aforementioned "lUf" and a finished paper container coated on the inside with vegetables and fruits in the same uncoated group. Take a photo of two paper-made containers prepared by AA and other mentioned 'in order to confirm the freshness within a specified time, carbon coating j /, on the inner surface of the paper-made container. The experimental state of the coating deodorizing effect. The condition a is the same as the previous one. It can be quite clearly known that in the paper container made of the former paper, the meat can be maintained for a longer time than the uncoated container = coated with carbon. The paper of the coating layer is reduced by the carbon contained in the carbon coating layer.

Description of Invention (7) " To obtain the aforementioned freshness maintenance effect and maintain the freshness of foods such as vegetables. In addition, it can also be confirmed that the paper coated with the carbon coating layer has good water resistance and oil resistance. In addition, 'can also confirm : In terms of the safety of the carbon-coated paper, the analytical value of any of the consumption of lead, cadmium, heavy metals, and potassium permanganate is' No. 2 published by the Ministry of Health of Japan. 〇 The allowable value of Article 0 is below, so it can be safely used for food packaging. 0 [Effects of the invention] As described above, by using a certain surface of the wrapping paper or the coating layer of a paper container, ' The carbon paper grain maker can be used for various food or fresh food paper containers with a so-called deodorizing function. According to the present invention, since a carbon coating layer coated with carbon powder is provided on the inner surface, Make the package Paper or humidity control function is the most suitable for multi-purpose storage and packaging. In addition, there are many kinds of storage, such as bento, which can prevent foods from interfering with each other by deodorizing function. &Quot; The state of the mouth appears to occur, and there will be no phenomenon that reduces its original taste. The taste of the product will increase the value of the product. At the same time, it can function to adjust the moisture of the food by 0 moxibustion, so as to maintain it. f. Humidity adjustment of the coating layer In addition, it can also be processed by the aforementioned method, and the water state of long ^ ^ =, freshness of fresh food. θ also maintains vegetables [Description of element number] 1: Paper container
