Description

Anarchy for packaging moisture-containing materials and manufacturing method thereof ganpi paper and manufacturing method the same

The present invention relates to ankyl paper for packaging a water-containing material and a method of manufacturing the same. More specifically, the present invention relates to an oil-coated paper that is tough and soft and has excellent moisturizing and moisture-proof functions to prevent damage, rot, and drying that may occur during distribution of water-containing substances such as red ginseng, and a manufacturing method thereof.

An example of the need for moisturizing and moisture proofing during distribution is red ginseng.

As is well known, red ginseng is "the ginseng that is not dried, that is, steamed and dried by steam or other methods. The Ginseng Industry Act." It is important to maintain pharmacological ingredients and maintain quality control during the distribution process. This is a very important issue.

On the other hand, as a wrapping paper for packaging red ginseng, traditional Korean paper or thin and soft sun paper has been used.

Among them, traditional hanji exhibits excellent tensile strength and excellent moisturizing and moisture proof function by using paper mulberry as the main raw material.The manufacturing process of traditional hanji is 'making main raw material', 'boiling', 'washing and sunburning'. It consists of winning, tapping, making paper, draining, drying, and trimming.

Looking at each, first of all, to make the main ingredients, cut the bark from the tree between November and February so that the bark can be peeled off. Peel the skin from the bark of the skin (外皮) and peel off only the white skin (白皮) and then dry well and soak in cold clear water for a day or two.

Next, in order to boil, cut the white soaked soybeans into proper size and put it in a pot with lye and boil it for 4 to 5 hours. For reference, sodium carbonate (Na ₂ CO ₃ ), sodium hydroxide (NaOH), and sodium sulfate (Na ₂ SO ₄ ) are used instead of lye.

Next, in order to 'wash and sunshine', leave enough boiled white pears in the duck pot for about one evening, insist on moxibustion, and rinse in running clear water to remove sugar, ash, oil and lye other than fiber. And spread the white skin in the water and evenly turn the sun over evenly and bleached white using oxidative bleaching action by ozone (O ₃ ), hydrogen peroxide (H ₂ O ₂ ). For reference, bleaching powder, sodium hypochlorite (NaOCl), and sodium zinc oxide (NaCIO ₂ ) are used for bleaching white skin.

Next, for tapping, take out the white skin and put it on the stone, and then beat it for 40 ~ 60 minutes with the bat to tear the mulberry fiber. This process is also known as confession (叩 解), and the time of tapping is somewhat different depending on the type of paper (있지만), but ends up when the fiber volume is about twice as large as the first time the fiber is protruding. For reference, mechanical confession is mainly used using a machine rather than tapping by hand.

And after the confession is finished, the raw material from which the fibers are released is put together with water into a barrel such as wood, and stirred with a round stick to dissociate.

Next, in order to 'paper-making', the paper is added to the disintegrated raw material such as paper mulberry, sodium polyacrylate (polyethylene oxide), polyethylene oxide (polyethylene oxide), and shake the paper roll from side to side to obtain a thin fiber layer thereon. At this time, the 'paper knitting' method is shedding and confinement. Traditionally, shedding and unilateral knitting were used, but nowadays twinning, which is an intermediate form between confinement and shedding, is mainly used.

Next, in order to drain water, the wetlands on the grasslands are piled up, and then pressurized and dehydrated by applying pressure.

Next, for 'drying', the wetland where 'water draining' is completed is dried in an ondol room or in the sun and completely dried. Finally, the traditional hanji is completed through 'trimming'.

On the other hand, traditional Hanji has excellent tensile strength, but it is difficult to soften the quality of the paper, and the manufacturing cost is high and the manufacturing process is complicated, and thus the price competitiveness is poor as a wrapping paper. On the other hand, Yangji shows a problem that the contents are easily decayed or dried during the distribution process when used as a wrapping paper of water-containing substances such as red ginseng because it is thin and soft but has poor tensile strength and is not easily moisturized and moisture-proof.

The present invention has been made to solve the above problems.

That is, the present invention is a wrapping paper suitable for packaging and distribution of the contents of the moisture content, such as red ginseng, can be obtained in a relatively low cost, a simple process in place of the traditional hanji that the manufacturing cost and the heavy burden on the manufacturing process, Showing the tensile strength and moisturizing and moisture-proof effect similar to the traditional Hanji, and its purpose is to provide a thin and soft anterior paper and a method of manufacturing the same to the sunny.

In order to achieve the above object, the present invention provides an anhydrous paper for packaging a water-containing material, including mulberry, hemp pulp, Abaca pulp, U.K.P pulp, B.K.P pulp, S.P pulp, the skin pulp.

At this time, the mulberry, hemp pulp, acaca pulp, UKP pulp, BKP pulp, SP pulp, anchi pulp is characterized in that the weight ratio of 2: 2: 2: 1: 1: 1: 1, Base paper made of a base layer; And an overlap made of the same material as the base and overlapping the base to form a watermark.

In addition, the present invention provides a method for producing an oil paper for packaging a water-containing material, comprising the steps of: (a) pulping the mulberry; (b) the strength enhancer after mixing the pulp, abaca pulp, UKP pulp, BKP pulp, SP pulp, and anthamp pulp on a weight ratio of 2: 2: 2: 1: 1: 1: 1 Injecting and confessing to form a stock; (c) injecting polyethylene oxide into the beaten paper and then papermaking to obtain a wetland; (d) it provides a method for manufacturing an oil-free paper for packaging a water-containing material comprising the step of winding the wetland in a roll dehydrated and dried.

At this time, the step (a), (a1) preparing the mulberry tree; (a2) first cutting the prepared mulberry tree; (a3) cooking by adding sodium hydroxide to the first cut mulberry; (a4) fermenting the cooked mulberry; (a5) first washing the fermented mulberry; (a6) bleaching by adding sodium hypochlorite to the second washed mulberry; (a7) second washing the bleached mulberry; (a8) characterized in that it comprises the step of dewatering and secondary cutting the second washed mulberry.

In addition, the step (c), the base paper and the overlapping paper with a single net and a ring network, respectively, and the step (d), the base paper and the overlap is wound around the roll together to form a watermark in the wetland do.

The present invention provides a wrapping paper for packaging and distribution of the contents, such as red ginseng, the maintenance of an important moisture content is important, durable and soft, excellent moisture-proof and moisturizing function and its manufacturing method.

In particular, the present invention is excellent in terms of manufacturing cost compared to traditional hanji using doc only by using a mixture of ready-made pulp at the same time can express the unique characteristics of each pulp, tough and soft, excellent moisture-proof and moisturizing function, composition and papermaking Since the whole process can be mechanized, it has the advantage of high yield in the manufacturing process.

In addition, the vellum according to the present invention has the advantage of being able to insert a watermark according to the purpose to maximize the advertising effect of the article.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

Prior to the full description, some terminology used in the present specification will be described in advance. 'Anti-ji' refers to a paper made of the original anarch (fibrous) fiber, but is usually made of a similar paper using a camphor tree. It is to be understood that the name of the 'Anti-ji' according to the present invention is to consider the latter conventional concept.

Accordingly, the term 'duck' also refers to all kinds of bast which can be used as a material of paper, for example, Wikstroemia trichotoma, which belongs to the deciduous shrub of the A. They include general species such as Edgeworthia papyrifera), Diplomorpha sikokiana, which belongs to the deciduous tree of the dicotyledon, and the duct tree (Broussonetia kazinok) which belongs to the deciduous shrub of the dicotyledon.

In addition, the term 'pulp' refers to a collection of cellulose fibers obtained from wood or other fiber plants through mechanical, chemical or intermediate methods. The following 'pulp' is used to make fiber plants such as wood into pulp. The process, ie, the process of changing into cellulose fiber aggregates, is generically referred to.

Other necessary terms are discussed in that section.

1 and 2 are flow charts illustrating a manufacturing process of an 'antique paper for packaging a water-containing material' (hereinafter, simply called an oil paper) according to the present invention.

On the other hand, the manufacturing process of the vellum according to the present invention is a 'pulping process' to pulp the mulberry tree,' mixing, beating and cooking the pulp of mulberry with other ready-made pulp to make a thin paper needed for grassland Composition process, a 'papermaking process' which completes the sebum in accordance with the present invention by dehydration and drying of the wetland from the stock, and the milling and finishing process of processing and treating the sebum according to the needs of the user. It can be divided into

Accordingly, FIG. 1 corresponds to the 'pulping process' among the anthographic paper manufacturing processes according to the present invention, and FIG. 2 corresponds to the 'composition and papermaking process', and will be described according to the order thereof.

First, prepare the mulberry, which is the main raw material of the vellum according to the present invention, and then remove impurities and other dirt. (St11) At this time, if necessary, only the white skin can be separated from the skin of the skin, and for this purpose, a conventional method is used. Can be.

Next, the selected mulberry trees are first cut to a predetermined length, preferably 30 to 40 cm. (St12)

Next, put the first cut mulberry tree in a cauldron and add 50% by weight of sodium hydroxide solution to add weight to the mulberry (st13) at this time, the non-fibrous material in the mulberry tree melted through the step It is removed and a relatively pure fibrous component is obtained.

Next, the cooked mulberry is fermented for 3 to 4 days. (St14) To this end, the cooked mulberry is stacked on a wooden board and then adjusted to a temperature not lower than room temperature and not higher than 60 ° C. during the same period while maintaining appropriate humidity. Can be.

Next, the fermented mulberry tree is first washed. (St15) At this time, the washing liquid uses fresh ground water, which is clean ground water, and preferably high iron content.

Next, bleached by adding sodium hypochlorite corresponding to 30% by weight of the base of the mulberry to the first washed mulberry (st16).

Next, the bleached mulberry tree is washed twice to remove the bleach component. (St17) At this time, the cleansing liquid is used as clean ground water as before, and the iron content is preferably high.

Next, dehydrated mulberry is washed twice to remove moisture and then cut into 5 to 10 cm in length. (St17, st18)

As a result, the pulp of the mulberry tree, which is the main raw material for the production of sebum according to the present invention, was completed, and then, the composition and the papermaking process for the production of sebum according to the present invention will be described with reference to FIG. 2.

First, after mixing the pulp of the mulberry tree and two or more general ready-made pulp through the process of st11 to st19, and then add a strength agent corresponding to 0.5% of the total mixture 5 to 6 hours confession. (St21, st22) Through this, the paper grain and strength improvement of the sebum in accordance with the present invention is achieved.

At this time, the ready-made pulp may be Doc and / or cedar pulp, Sanya pulp, Manila hemp pulp, Abaca pulp, Unbleached Kraft Pulp (UKP pulp, Bleached Kraft Pulp (BKP) Phosphorus BKP pulp, Sulphite Pulp (SP), Pulp (Ansulfone Pulp), and Pulp Anthrum (Pulp) is used, and pulp of mulberry, Sanya pulp, Abaca pulp, UKP pulp, BKP pulp, SP pulp, and anchipulp The mixing ratio is 2: 2: 2: 1: 1: 1: 1. For reference, Sama pulp, Abaca pulp, U.K.P pulp, B.K.P pulp, S.P pulp, and anthop pulp is a pulp widely used in the field, so a separate description is omitted.

In addition, a dedicated beater or double disk refiner (DDR) machine and one or more mixing chests can be used for confusing at that stage, and if necessary, pulp with pulverizing prepulper. Screening, debris condensation using a decalator, prior to or after the step of slurrying, removing foreign matter in the pulp using a screen or cleaner, or separating fibers using a deflaker Removal of fibers, bubbles, and the like can follow.

Thereby, the thin paper material required for papermaking is obtained.

Next, polystyrene oxide, which is a viscous agent, is added to the stock, followed by papermaking to obtain a wetland with a thin fiber layer. (St24)

At this time, in particular, the paper of the step is a net for obtaining base material from the first baht and the stock contained therein, and the top layer necessary for implementing the water mark from the second baht and the stock contained therein. The ring network to obtain the overlap can be made in a so-called 'mono-network complex paper machine' installed. As a result, a wetland in accordance with the lamination of the original paper and the overlapping paper is rolled up as a roll at the rear end of the paper machine, and a predetermined watermark is engraved therein.

Next, the dewatering and drying of the wetland wound on the roll is completed, the papermaking process is completed, and the substantial sebum in accordance with the present invention is completed. In this case, the pressurized dewatering method using a press may be used to dehydrate the wetland, and the multi-dry drying method using at least one drum may be used to dry the wetland. In addition, if necessary, sizing using a size press after drying, surface strength and printability improvement through pigment coating, and separate drying, thickness and smoothness adjusting process using a calender may be performed.

In addition, depending on the user's choice, after finishing the papermaking process, a coating process for coating and drying a separate paint, giving a high gloss, and a finalizing process for cutting and packing the unit to an appropriate size may be performed. As it may be, a separate description is omitted.
