Generally, wax is used in various fields because it has a gloss, lubrication, waterproofing, and antiseptic effect due to its property of easily changing to a fluid at room temperature while being solid at room temperature.

Such waxes include petroleum waxes, animal waxes, vegetable waxes and mineral waxes. In the present invention, it is most preferable to use petroleum-based paraffin waxes, but in some cases animal, vegetable and mineral waxes may also be used.

In addition, the petroleum paraffin wax used in the present invention should be nontoxic.

In the present invention, bentonite, zeolite, tourmaline, and the like may be used as a material for mixing with paraffin wax to increase antimicrobial properties.

First, the zeolite used as a material to be applied to the wrapping paper of the present invention is a silicate mineral of aluminum containing alkaline earth metals such as alkali metals of sodium and potassium and calcium, and also containing crystallized water. There are two kinds of thing, clinoptilolite and morden knight.

Zeolites, which are naturally produced as rocks or clays, are altered tuffs, which are less than synthetic zeolites, but have strong adsorption and occlusion, and base substitution capacity.

This exchange action allows zeolites to be ionized in water and replaced with ions from other electrolytes. All zeolite groups are acicular, columnar, rhombohedral and abstract, colorless or white and sometimes pale.

Specific gravity is 2 ~ 2.4 (2.7), hardness is 3.5 ~ 5.5 It can be dissolved at low temperature and water is easily released when heated, but there is zeolite water in it.

Natural zeolites have been used for many purposes.

For example, it is used as an additive for livestock feed to promote the growth of livestock, mix with soil to increase crop yields, and especially in Italy, as a building brick to maintain a constant temperature and humidity in the room regardless of the change of season. It is also applied to.

Zeolite has a three-dimensional solid structure consisting of Al ₂ O ₃ and SiO ₂ tetrahedron, Pore and Channel in the structure, and ion-exchangeable metal ions. Due to such structural properties, there are various applications such as water treatment agents, molecular sieves, catalysts and catalyst carriers, and detergent additives.

Bentonite used in the pavement of the present invention is a mineral produced by volcanic ash and lava due to volcanic eruptions in the beginning of the earth's earth generators for a long time deposited in the sea by the earthquake.

Also known as montmorillonite, it is a broad name for bentonite.

In the US FDA, all bentonite (montmorinite) is categorized under GRAS, and bentonite is used for food digestion and various diseases (allergic, periodontitis, streptococcus of the esophagus, gastric ulcer, nausea, anal rectal bleeding, diarrhea, wasps , Athlete's foot, wounds, acne, swelling, female yeast, dandruff, fever, itching, etc., as well as clearing blood and relieving nervous system stress, promoting metabolism and vitality. A mineral that has an excellent effect on treatment.

(1) eco-friendly, safe and stable minerals

Because it is mineral, it does not rot like organic matter. It is strong against heat and stable up to about 700 degrees.

(2) swellability

Bentonite is very water-friendly, and when it comes in contact with water, it absorbs water and swells up to several to several tens of its original volume like a jelly image.

In addition, I hold the water which I took in myself and prevent it from coming out.

(3) absorption

Not only water, but also oil, dirt and smell can be absorbed.

(4) Sol / Gel Formation Ability

Bentonite can form Sol by only adding a small amount to water. This Sol hardens like Gel when left unattended.

(5) Make a thin film to protect it.

Bentonite liquid has a property of making a smooth film.

Tourmaline used in the present invention is a mineral belonging to the hexagonal system, which is a type of igneous rock, with positive and negative poles naturally occurring at both ends of the crystal, and the weak current flowing permanently. Also called (電氣石), the hardness is 7.0-7.5, the specific gravity is 2.98-3.20, and the chemical composition is complex borosilicate of iron, magnesium, alkali metal and aluminum, and it is usually composed of six or nine pillars. As one of the three materials that have energy on their own on earth, such as uranium ore, magnetite, etc., absorbs energy in large quantities, and emits energy semi-permanently to invigorate the human body.

Tourmaline is a mineral discovered in Sri Lanka in the 18th century. It is also known as tourmaline when the Curie brothers of the 19th-century Solvoli University pressurized the crystal and created a charge on the surface of the crystal. Tourmaline is rich in colors such as diamond, transparent, pink, light green, blue, red, and purple, and is mainly produced in Brazil, California, Sri Lanka, and China.

Nakamura-shi and Kubo-shi of the University of Tokyo, Japan, who studied the properties of tourmaline, have demonstrated that tourmaline spontaneously generates positive and negative electrodes at the anode of 3 micron crystals. A potential difference of up to one million volts occurred at this anode and a weak current of 0.06 mA was found to flow permanently. In addition, Kubo's team investigated the properties and functions of water by mixing and sintering 3 micron tourmaline with low-conductivity ceramics to make spherical pallets with a diameter of 3 mm. According to this, water is electrolyzed with a (-) electrode to approach a neutral pH, and hydrogen ions are generated at the (+) electrode to impart an interfacial action to water. In addition, it proved the fact that by destroying the cluster of water to make the active water to increase the penetration into plant cells.

In addition, tourmaline contains elements and minerals that have a good effect on the human body, such as boron (B), which helps the skin's mucosal relationship and growth promotion, silicon (Si), which has cosmetic effects in the stomach, liver, and liver, Magnesium (Mg), a blood relationship, and heart-strengthening minerals, which are good for cardiac strengthening, are used to improve health (Fe) and neuro-stabilizing calcium (Ca).

Tourmaline is good for the human body, such as magnesium, which is good for cell activation and heart strengthening, boron, which helps to promote the mucous membrane relationship and growth of the skin, and silicon, which is good for beauty, silicon, blood relationship, and calcium, which stabilizes the heart. It is rich in elements and minerals that affect it.

Due to the electrical properties of tourmaline, the weak current generated steadily stimulates the acupuncture points in the human body, improving peripheral circulation and promoting blood flow, which is effective in hypertension. It has the effect of dislocation treatment, etc., and promotes blood circulation and metabolism, and has effects such as fatigue recovery, gastrointestinal activation, relief of pain and sleep and cold symptoms. In addition, tourmaline has a large amount of negative ions generated by electrolysis through contact with moisture, which has antibacterial, deodorizing and cleaning effects, and improves acidified body fluids into weakly alkaline constitutions, thereby providing stability to the human body.

The far-infrared rays and negative ions act as neuralgia, arthritis, back pain relief, soothing effect of skin, diabetes, constipation pain, deodorization, antibacterial, dehumidification, water softening, air cleaning.

Tourmaline swells capillaries by synergistic effects of negative ions and far-infrared effects, promoting body temperature, skin activation and metabolism. The synergistic effect is caused by the tourmaline absorbing the heat released by the human and returning it back to the human body. Therefore, the capillaries are widened to promote blood circulation. It is effective for skin recovery, activation of gastrointestinal movement, neuralgia, shoulder jam and coldness.

As described above, tourmaline has been found to have various effects, and in recent years, due to the effect of additional anions with the effect of far infrared rays, interest and demand in developed countries and domestic countries have increased.

Far-infrared rays emitted from tourmaline promote blood flow in the human body and promote sweating (discharge of waste), neuralgia, arthritis, back pain relief, soothing effects of skin, deodorization, antibacterial, dehumidifying, softening (water), air It acts as clean.

The action of the tourmaline is to generate electricity by the microscopic heat flows a weak current to contact the heat (body temperature) of the human body to heat transfer by stimulating the menstrual blood and improve the peripheral circulatory system to promote blood flow Negative ions are known to have antibacterial, deodorizing, and cleaning effects. Cell activating effects have potential treatment effects such as constitution improvement and blood purification.Also, large amounts of far-infrared rays are released due to the properties of minerals to cover cells deeply and promote blood circulation. It helps to recover from fatigue, gastrointestinal activation, pain and shoulder stiffness, sleep and cold symptoms as well as antibacterial and bactericidal action, and converts harmful cations generated in home appliances into anions. Sometimes.

Eventually, tourmaline promotes metabolism in the human body, and has a function of cell function, immune function activation, blood purification, and autonomic nerve stabilization. And it can be converted into water that is good for the skin with excellent moisturizing effect, and far infrared rays emitted from tourmaline promote the flow of human blood, promote sweating (discharge of waste), sooth the skin (face), deodorize, disinfect, dehumidify, soften (Water) and air cleaning.

Bentonite, zeolite, and tourmaline used in the present invention are ground to a predetermined size and mixed with powdered paraffin wax, and the size is preferably produced using a particle size of about 1000 to 3000 mesh.

In addition, the ratio of paraffin wax mixed with paraffin wax 95 ~ 99.99% by weight of one or more minerals of bentonite, zeolite and tourmaline is preferably contained 0.01 to 5% by weight.

When the content of bentonite, zeolite and tourmaline is less than 0.01% by weight, it is difficult to expect the effect, and when it is 5% by weight or more, the adhesion to the base paper is reduced and the coating is peeled off at a temperature of 50 to 60 ° C. or more. There is concern.

In addition, by adding a certain amount of polyethylene (PE) in addition to bentonite, zeolite, and tourmaline to the paraffin wax may further increase the melting point of the coating.

When added by adding the polyethylene can be used by adding about 1 to 20% by weight relative to the total weight. In other words, when the amount of polyethylene added is less than 1%, it is difficult to expect the effect of increasing the melting point, and when more than 20%, it is difficult to see the effect of the addition of the group consisting of other adducts, that is, bentonite, zeolite, and tourmaline. Most preferably, it is added between 1 and 20% relative to the weight of the coating.
