More specifically, beneficial physiologically critical minerals assisting a regenerative ability of the human body are contained in the most ideal conditioning. More specifically, the present invention has a harmful component suction force, an antimicrobial function, and an antifungal function to significantly store food and maintains freshness for a long period of time.

Description

TECHNICAL FIELD [0001] The present invention relates to an antimicrobial functional food film,

The present invention relates to a method for producing a functional food packaging material having antibacterial activity, and more particularly, to a food packaging material prepared by mixing synthetic resin as a main raw material and fine granules (pegmatite).

Gyeongseok is a granitic rock which is found mainly in the dyke containing plutonite. It is formed as plutonite and volatile materials such as chlorine, fluorine and water are concentrated in the residual magma residue and slowly cooled. It is composed of beryllium, uranium, niobium, tantalum, And many other rare minerals are precipitated. Especially beneficial physiological minerals that help the human body's regenerating ability are contained in the most ideal harmony.

In addition, Gyeongseok is rich in magnesium, sodium, silicon, calcium, and other necessary components for human body. It emits a large amount of negative ions, absorbs harmful components, and has antibacterial and antifungal functions. Is excellent in storage stability as a food and has an effect of maintaining freshness for a long time.

One of the key areas of business for food packaging materials is maintaining freshness and storage. Especially, vegetable and fruit are preserved by oxygen, microorganism and moisture. Presently, preservatives such as artificial additives have been used without a clear alternative. However, since these preservatives are detrimental to human health and adversely affect health, they also affect the unique taste and flavor of food, and thus new types of food packaging materials have been developed. Such packaging materials include yellow loess, elvan, silver nano But it has not been applied to the market sufficiently. So, we are trying to develop synthetic resin using pegmatite.

The present invention has been developed in order to solve the above problems, and aims to manufacture a food packaging material useful for a human body which has far-infrared rays and anion emission, antibacterial and sterilizing power by utilizing various functions of gyeongseok.

The object of the present invention is to produce a food packaging material for antimicrobial use by pulverizing and adsorbing rare earths containing rare metals such as titanium, holmium, selenium, niobium and tantalum as well as silicon, aluminum oxide and calcium oxide to about 2,000 mesh .

The food packaging material according to the present invention emits far-infrared rays and anions, enhances the adsorption power of heavy metals, harmful components and ethylene gas, and has an antimicrobial activity and an antioxidative activity.

The present invention relates to a method for producing a functional food packaging material having antibacterial activity, which is a food packaging material obtained by mixing low density polyethylene and ground stone, wherein the ground stone powder particles have a size of 2,000 to 5,000 mesh and 100 parts by weight of low- 5 to 15 parts by weight of particles,

(1) pulverizing gravelalloys containing silicon, magnesium and calcium into 350 mesh;

(2) self-crushing the 350 mesh ground stone powder at a speed of 2,000 ~ 5,000 mesh using a high-speed air eddy current or vibration due to high frequency pressure fluctuation;

(3) mixing 5 to 15 parts by weight of goethite powder with respect to 100 parts by weight of low-density polyethylene to prepare a master batch;

(4) mixing 5 to 15 parts by weight of the master batch with 100 parts by weight of the terpolymer in the sealing layer to produce a three-layer film through the cylinder.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described in detail with reference to examples of the present invention. It will be apparent to those skilled in the art that these embodiments have been presented for the purpose of illustrating the invention and that the scope of the invention is not limited by these embodiments. do.

Example  1. Food packaging materials manufacturing

In this embodiment, a food packaging material was prepared using gingolite. (See FIG. 1)

First, 5 kilograms of lump of natural minerals (less than 1 centimeter in diameter) and low density polyethylenes resin, which are added to food packaging materials, were prepared. Then, the above-mentioned gypsum lumps were firstly pulverized with a powder of 350 mesh.

The above ground gypsum powder was subjected to secondary processing at about 2,500 mesh with a high-performance pulverizing apparatus using magnetic pulverization using vibration of high-speed eddy-current or high-frequency fluctuation of air. The 2,500 mesh processing was taken into account the wear of the machine and the transparency of the finished product when printing the finished product.

The prepared 2,500 mesh gypsum powder and the low density polyethylene raw material were weighed at a ratio of 1:10 (5 kg of gypsum powder, 50 kg of low density polyethylene raw material), stirred in a mixer for about 10 minutes. The stirring speed was about 100 rpm.

The master batch made from the obtained raw materials was added to the master batch at a level of 5% by weight with respect to 95% by weight of the terpolymer in the sealing layer, and converted into a solid structure through a high-temperature vacuum tube.

Example: After going production that does not contain the packaging material containing the packaging crystallization Storage Evaluation

Packing materials were prepared using only 50 kilograms of polyethylene in the absence of gingelite, and gingelite was added in the same amount. Seven kinds of vegetables and vegetables were put into each packing material. (Fig. 9), Fig. 10, Fig. 11, Fig. 12, Fig. 13, Fig. 14, and Fig.

The results on the storage stability were found to be significantly different.
