Description

Packing paper including sack and packing product using the same {Packing paper including fiber of Sasa quelpaertensis Nakai}

The present invention relates to a packaging paper comprising a sack and packaging products using the same, and more particularly to a packaging paper manufactured using a pulp mixture comprising a sack pulp and wood pulp, and a packaging bag and packaging containers and packaging boxes using the same. will be.

As the manufacturing technology of paper develops day by day, a variety of papers are provided with various functionalities such as high strength, preservation, antibacterial and deodorant, and beautiful colors and patterns. However, many of the additives for providing functionality or decorative properties are synthetic chemicals, and these additives are materials that do not meet the demands of demanding consumers who want to satisfy various conditions such as stability and eco-friendliness at the same time as functionality and decoration. Therefore, there is an urgent need for the development of natural materials with stability and eco-friendliness along with functionality and decoration.

On the other hand, wood pulp widely used as a raw material of paper is made of wood grown for several years to several decades as a raw material is accompanied by serious damage to the natural environment and there is a problem that takes several years to several decades to recover the forest. On the other hand, in the present invention, using a raw material of paper is a kind of bamboo native to domestic wild and wild, it grows well in the poor land and cold, strong growth and breeding features. In particular, stalks hinder the growth of other plants and dry up the surrounding trees, which in turn interferes with the vegetation of various plants and in the long term destroys forest ecosystems. It can help you keep your balance In addition, it can be used as a material of paper that grows naturally, and it is economical because it is not difficult to grow even when grown, and it is easy to cultivate due to its strong breeding power, and it is particularly excellent in moisture permeability and antibacterial and anti-mold characteristics. Since it can be given to, it has useful features as a material of paper.

Accordingly, the present invention provides a packaging paper including a bridle as a paper having functional, safety and environmental friendliness, and also provides a packaging bag, packaging container, and packaging box using the same.

An object of the present invention is to provide a packaging paper and a packaging article using the same, which is excellent in moisture permeability, anti-mildew, and antimicrobial properties to extend the shelf life of food.

Another object of the present invention is to provide a packaging paper and a packaging product using the same by minimizing the damage to the forest and economic efficiency by replacing a portion of the wood pulp with a non-wood-based pulp.

In order to achieve the above object, the present invention extracts the fiber from the stalks to obtain the stalks pulp, and mixes it with wood pulp to prepare the packaging paper, and uses it to manufacture the packaging bags, packaging containers, and packaging boxes.

The scavenger pulp in the present invention is prepared by boiling the sack in water to remove water-soluble foreign matter and then cooking, washing, and dehydrating the scavenger fiber obtained by cooking.

In the specific method of producing the sauté pulp, the sachet is first collected and washed for fiber extraction to remove foreign matters, cut into 3 ~ 4 cm size, dried in the shade, and dried for about two days in the shade to remove moisture.

The dried stalks are put in water, boiled, and sieved to remove water-soluble foreign substances to obtain stalk fibers. In this case, if the boiling time is too short, foreign matters are not properly removed, and if the time is too long, the fiber may be damaged, and it is preferable to boil for 40 to 80 minutes, and after obtaining the fiber, the water is removed and naturally dried.

The wringed fiber from which water-soluble foreign matter is removed is cooked using an aqueous sodium hydroxide solution. The cooking step is a process for removing impurities from the fiber and fiberization, and simply by boiling with water, sodium hydroxide solution is used because impurities such as pectin and lignin are not properly removed. At this time, if the concentration of sodium hydroxide is high or the cooking time is high, the removal rate of impurities is high, but the damage of the fiber is not only high, but the yield of the fiber is low, and if the concentration of sodium hydroxide is low or the cooking time is short, the damage of the fiber is low and the yield is low. High impurity removal rate is low, but there is a disadvantage that a good fiber can not be obtained, it is preferable to cook for about 30 minutes with 4% by weight of sodium hydroxide solution.

After the cooking, the stalk fibers are dried in water to remove foreign substances, selected, washed with water, and dehydrated to prepare stalk pulp.

In the present invention, a wrapping paper is prepared by using the pulp mixture mixed with the scavenger pulp and wood pulp prepared by the above method. Specifically, water is added to the pulp mixture to make the water content about 90% by weight, and then According to the manufacturing method of phosphorus paper, papermaking, dehydration, drying, calendering to prepare a packaging paper. The manufactured packaging paper may be used directly as a packaging paper, or may be manufactured by cutting and adhering in the form of a bag, and may also prepare a packaging container or a box by cutting and adhering a thickly manufactured packaging paper. If the mixing amount of the scavenger pulp in the pulp mixture is too small, the moisture permeability, antimicrobial properties, and antifungal properties of the scavenger are not expressed and the effect of reducing the cost is reduced. It is preferable that the pulp mixture contains 5 to 90% by weight of scavenger pulp based on the dry weight ratio.

In addition, as the wood pulp used in the present invention, it is also possible to select paper pulp that is a recycled pulp. When manufacturing packaging paper using pulp mixture mixed with high pulp, the utilization of waste resources and cost reduction can be maximized. Therefore, paper made thickly using pulp mixture mixed with high pulp and sake pulp Is more suitable as a material for packaging containers or boxes.

In addition, the pulp mixture in the present invention may add additional functionality by including additional components in addition to including wood pulp and sacks.

For example, washing the peel of citrus fruits from which impurities are removed and cooking for 40 to 50 minutes in 4 to 5% by weight of sodium hydroxide solution, then removing the fibers to remove foreign substances, selecting, washing with water and dehydrating In the case of mixing the citrus pulp produced by the maximizing cost-saving effect, as well as beautiful colors and patterns, and can enhance the strength. At this time, if too little citrus foil pulp is contained in the pulp mixture, the desired effect is not sufficiently exhibited. If too much citrus pulp is contained, the bond between fibers may not be dense, increasing the volume and decreasing the strength. It is preferable to include in the range of 5-40 weight% as a reference.

As another example, the packaging paper may be prepared by mixing volcanic stone powder. If the volcanic stone particles mixed in the pulp mixture are too large, the paper becomes uneven, and if the particles are too small, the time or cost required for grinding increases, so it is preferable to use volcanic stone that has been crushed to a particle size of 10 to 75 μm. Since volcanic stone has characteristics of antibacterial, volatile organics removal, heavy metal adsorption and far-infrared radiation, further mixing of volcanic stone can eliminate the concern about the harmful effects of contaminated high-grade pulp. If too small, the effect of antibacterial, volatile organics removal, heavy metal adsorption, far-infrared radiation, etc. will be inferior. On the contrary, too much mixing will interfere with the bonds between the fibers, resulting in poor paper strength and poor texture. It is preferable to include in the range of -40 weight%.

As described above, the packaging paper manufactured using the pulp mixture containing the wood pulp and the scavenger pulp is excellent in moisture permeability and anti-mildew and has low cost. The wrapping paper including the sack of the present invention can manufacture paper having various characteristics by appropriately selecting and adding the components constituting the pulp mixture according to the purpose of use, and the prepared wrapping paper is used as a general wrapping paper, or It can be used to manufacture packaging products such as packaging bags, packaging containers, packaging boxes.

Packaging paper containing the scavenger pulp of the present invention is excellent in moisture permeability and anti-mildew, so when used as a packaging product of food has the effect of preventing the deterioration in the distribution process, there is an advantage of low cost. In addition, since the packaging paper of the present invention uses the non-wood pulp, the sabotage pulp can not only reduce the damage to the forest, but also help maintain the balance of the ecosystem when using the native sake as the raw material.
