Description

[Detailed description of the invention] Regarding the law.

Paper and paperboard have divine uses as packaging materials. Among them, kraft packaging paper and cardboard liners, which are commonly used, are manufactured from waste paper containing kraft pulp or kraft pulp.

By the way, kraft pulp is a pulp made by steaming with water (Kura 7 containing iljc-based soda); lW chemicals, and it also contains compounds such as wlr (L"rostrum and thiolignin). It was not possible to avoid the residue.

Also, for the corrugated core, use old corrugated paper as a fence or use wood! Since the paper is made from pulp that is steamed and prepared at a central location such as lk (,lAi), it contains .IITl value and lignin sulfone in each issue. It's okay.

These price-fulfilling compounds are also worth the price of gold GP. 4J and Tetsu no Kai Shokuru) Rui will run parallel to Hatsusho 1.

The first inventor of Honto was Iβ11. A pulp made from pulp 0, which does not contain yellow compounds 1, is prepared using pulp 0 as a raw material.
The materials used for packaging were prepared. (4, Riuaki 6-7
- / 3 left side 7 evening) When making paper using the pulp made in this way, various boat baskets were used to improve the strength of the paper and adjust the workability of the paper. Strengthening agents and sizing agents are added internally, but is it necessary to add these chemicals to the parts? , is conventional (if r4”.

The method of using aluminum was 4'r 3;'':r. That is, in this way, K (llf+: acid aluminum is added to 7 or lupus slurry and papermaking is carried out in the acidic region of pHll- to 5.5. Therefore, it is also called the acidic shogan method, and it was inevitable that the obtained mackerel T]11 would also be acidic.

Therefore, if gold or rho-grain materials are added using a craft packaging bag or corrugated pole obtained by the conventional H-sensho-shin method, rust will occur due to the contact between the paper and the metal. The outer layer of the gold material, which is the package contents, can prevent the progression of corrosion and corrosion.
There was a tendency for this to impair product quality and functionality, and to significantly lower product prices.

In order to overcome these drawbacks, the present inventor has already devised a method for producing gold material composite paper using a neutral paper making method. (Tokugan Sho...!i-7-/3 A2
3 9) As mentioned above, there are many factors that cause people to lose money.

However, there is a high humidity level in this area, and the soil has been kept under the ground for a long time. It has been found that the outbreak of cape is accelerated due to the influence of bacteria etc. that occur in the area.In particular, the connection point 1 used in the town where the danboru route reaches the end of the island is accelerated. 11 In other words, the first generation of adhesives using starch, such as Stinhole starch glue, starch yarn made with high amylose starch and water-resistant A, etc.
, easy to do.

In addition, the pulp that is made from pulp containing waste paper is also used as a raw material, and is not produced in a natural way. In this way, when mold and qa:, defeat go to J, pl・kai 11,, -1・and this mimic creature generates drunkenness: +%. ((Ij' from C 4:, ・; threat j
is decomposed and GO2, NH3, H2S, 82504BC, etc. are generated, creating the Shinto 1fA1meal'B boundary. In addition, hydrogen may be depleted due to bacteria and a portion of the packaging material may act as a cathode, promoting corrosion, or aerobic bacteria may cause hydrogen depletion. A portion of the packaging material becomes an anode and promotes the body's meal.

The four unexploded units were placed in the above 9 shape, and the packaging material with the metal W value was troweled according to the Bow C method.

As a result of discussions, the present invention has been completed.

In other words, the present invention is suitable for use with metals that do not require occasional application of pesticides. Concerning the method for preparing the material for the use of sexual substances.

Before use in the present invention? Murder ■． Examples of agents include: benzoic acid and its salts, salicyl IO! / Hiso T・

[<: and its toyshi, p-oxy rest? Among 'tH alkyl esters, zolopions and their IRo compounds, it is preferable to use compounds that do not themselves contain sulfur compounds or local compounds.

1. As if the cow'1 were a feminine character, it would be false.・Ma, dehydro m1, shi, p-oxybenz'J pH〆ν of alkylnisder, sorpine fermentation, or its alkaline base should be used.

In addition, the filter paper used in the present invention is 1η
The paper used for regular packaging is deeply hated and
There is no heart. - Paper coated with a volatile rust preventive agent (examples include nocyclohexyl ammonium nitride, etc.), paper manufactured using the neutral paper-making method, from a request to increase the anti-seismic force 1 north by -161 times. Paper coated with an additive (such as sodium nitrite) that improves the fender's effectiveness, paper made from pulp 0 that has been steamed with Naro steaming liquid, and paper that does not contain sulfur.
etc., the effect of non-invention increases synergistically.

In the present invention, metal material packaging paper is produced by applying the above-mentioned killing agent I to paper.

In addition to application, the fungicide can be used alone or in combination. In history, it is used in the form of a solution, for example, dissolved in caustic soda, etc., or in an emulsion-like state if necessary (or depending on the physical properties of the disinfectant used).
do.

Furthermore, in the present invention, processing chemicals commonly used for paper, such as surface coating composition 1 (starch, polyvinyl alcohol, etc.), anti-corrosion ax 11, etc., can be mixed and used depending on the core properties.

The bactericidal agent added in the present invention can be added at the papermaking mill's II# and various mill stages and by various known methods. For example, methods of adding by spraying, impregnation, etc., such as size press, case roll coater, machine calender water doctor, etc. can be praised.

Each of the above disinfectants: Addition of agent I, addition of fungicide (rHc)
71 (approximately 0.07% to 3%, fj-!- or approximately 0.0.2°10 to /% of Use within range.

As mentioned above, the gold-based packaging paper produced by the method of the present invention does not have a specific period or purpose, such as liners for 911 and 2 balls, cores, cores, etc. Or general white paper, not limited to wrapping paper,
This includes filter paper and all 19 papers used for packaging metal materials.

The material for packaging a gold-rich substance can be laminated with an adhesive or the like, and a stretched container such as a bag, a paper box, or a cardboard can be manufactured, for example. In particular, Juku Hayabusa★11 is a water-resistant starch paste and vinyl acetate/vinyl acetate paste made with Stinhall-type starch, high amylose starch, and a water-resistant agent.
When using a 3-component glue containing pVA/filler, mold is likely to grow and may encourage bird eating by Japanese goldfish, so using the packaging paper of the present invention 4) Even more advantageous.

In addition, in the foregoing, it is desirable that the disinfectant used in the present invention be contained in the contact agent used. Materials packaged in containers, boxes, etc. are easier to use than conventional wrapping paper or packaging containers, and are easier to use than conventional wrapping paper or packaging containers. It is also possible to reduce the proliferation of microorganisms and the occurrence of rods at the Qn end. The conventional method is 11:9 and is extremely fCi delivery ~1. ++'-B4 In short, the industrial effects of the present invention are immeasurable.
