Description

Nano silver and coating wrap {Nano silver and coating wrap}

The present invention is directed to a wrap (20) useful for packaging food, as said above; Recently, a large amount of suspected environmental hormones have been detected in plastic wraps for food or products used in restaurants, etc. in the airborne news broadcasts. Especially, wraps are often used for packaging hot food such as jajangmyeon, which is a high risk of harmful substances leaking out. It was broadcasted that consumers' attention was needed, and 6 kinds of polyvinyl chloride (PVC) wrap packaging materials are widely used in restaurants, large discount stores, and food stores.

 According to a test conducted by the Korea Research Institute for Chemical Testing, five products were found to be susceptible to environmental hormone suspected di-2-ethylhexyl adipate '(DEHA).

The amount of DEHA was 23.7 ~ 25.9% by weight, and there was no difference between products.

 The undetected product is the L company's 'L-Lab', which is known to use a substitute new material instead of DEHA as a plasticizer. An official of the Korea Food and Drug Administration said, “In the case of PVC wrap, it is common to add plasticizer (100) to keep the wrap tight in food containers.“ 10 ~ 60% of DEHA is added, and the ratio is about 35%. Explained.

DEHA is a kind of plasticizer that mainly improves adhesiveness and softens plastics. Chemicals that are classified as environmental hormones or equivalents by WWF, Japan's Ministry of Health, and US Environmental Protection Agency (EPA A) are studied. to be. The Ministry of Environment of Korea classifies this as an endocrine obstruction observation object and investigates the environmental residue and ecological impact, but there is no content acceptance criteria in the product.

As mentioned above, one of the things used in homes and restaurants without falling out these days is a thin plastic wrap 20 made of a synthetic resin material.

The use of the wrap 20 is to wrap the food or eat the leftover food in a container with a lid, without the inconvenience of simply putting a wrap or a wrap it can be stored without odor or warming food before putting it in the microwave wrap 10 Or by wrapping the wrap 20 is used very conveniently as it can prevent the evaporation of moisture to prevent food from hardening;

 Even if you go to a small supermarket in front of a large mart or house, the food is wrapped in a wrap, and the whole food is covered with a wrap (10) so as not to spill the contents, and from then on, the wrap (20) is indispensable in our real life. It has become an important being.

The wrap 20 is a transparent, clean and just look at the wrap 20, which is just a piece of vinyl. The raw materials of the wrap 20 are divided into vinyl chloride and polyethylene based synthetic materials.

The vinyl chloride wrap 20 is made of a material such as polyvinylidene chloride, which is easy to use because of its low manufacturing cost and flexibility, and considers carcinogens such as dioxins when incinerated. In case of), not only the material but also various additives such as stabilizer 80, plasticizer 100, flame retardant 120, and mildew inhibitor are used to increase or soften the heat resistance and make it easier to use.

Although only two or three kinds of additives are described on the back side of the packaging wrap 20, much more additives are actually used, and the vinyl chloride system is used in the food wrap 20 for the following reasons.

Polyethylene wrap, which is said to be relatively safer than vinyl chloride when used for heating food, has a heat resistance temperature of 110 to 120 ° C, whereas a vinyl chloride wrap has a high heat resistance of 140 to 160 ° C.

When heating food, the cooking time is relatively short, so elution of environmental hormones is not a concern, and it can be said that it is safe because the heat temperature is higher than that of polyethylene.

Most vinyl chloride wraps (20) use algivinic acid esters as softeners. The safety of this material has not been confirmed, and commercially available wraps have mandatory quality labeling. The general public has no idea what it is or how much additive it affects the human body.

Phthalic acid esters and the like are added to vinyl chloride wraps. Butyl butyl benzyl and n-butyl phthalate are the representative substances, but these are known to act as estrogens (female hormones). The possibility of elution of environmental hormone substances in the process of heating food with a wrap cannot be denied.

In particular, oil, unlike water, can easily rise in temperature, and if cooked with oil is wrapped in a wrap and warmed in a microwave, it is a difficult reality to say that it is good to eat.

The present invention relates to an environmentally friendly functional wrap 20 produced by coating or applying a silver nano 40 material and the fragrance 60 to the body of the wrap 20 made of synthetic resin;

The wrap 20 is used not only for the storage of perishable materials such as foodstuffs, but also for use in containers and for the protection of various articles and has a thickness of about 0.00025 mm (about 0.00001 inch) to about 0.0051 mm (about 0.0002 inch). .

The present invention relates to a wrap that is a kind of packaging material for packaging food and products that are anti-sterilization and far-infrared anion emission, and more particularly, to a packaging wrap having the physical properties and hygiene required in the manufacturing process of the product or food.

As mentioned above, one of the things that are used in homes, industrial sites, and outdoors these days is the wrap 20.

The use of the wrap 20 is to block the outside air when packaging the food or products, as described above, can be stored without decay or odor for a long time, and when the food is put into the microwave to operate it prevents water evaporation to harden the food It can be prevented and the contents can be heated easily, which is very convenient for our life;

 Even if you go only to a small supermarket in front of a big mart or house, food that is worth packing is wrapped in a lap. From now on, the lap (20) has become an indispensable part of our real life.

The raw material of the wrap 20 is largely divided into vinyl chloride-based and polyethylene-based resins. The vinyl chloride-based wrap 20 is made of a material such as polyvinylidene chloride, which is easy to use because of its low manufacturing cost and flexibility. While incineration is very paying attention to carcinogens such as dioxin, the lab 20 is not only a material but also a stabilizer (80), a plasticizer ( 100), flame retardant 120, a variety of additives such as mold inhibitors are used.

 When heating foods, cooking time is relatively short, so elution of environmental hormones is not a concern, and it can be said that it is safer because it has a higher heat resistance temperature than polyethylene-based. However, vinyl chloride-based wraps (20) mostly contain alginate esters. Although it is used as a softening agent, the safety of this material has not been confirmed, and commercially available household wraps require a quality label, but as a softening agent, only the labels of fatty acid derivatives, etc. are used. We do not know at all whether it is additive.

Phthalic acid esters and the like are added to vinyl chloride wraps. Butyl butyl benzyl and n-butyl phthalate are the representative substances, but these are known to act as estrogens (female hormones). The possibility of elution of environmental hormone substances in the process of heating food with a wrap cannot be denied.

In particular, oil, unlike water, can easily rise in temperature, and if cooked with oil is wrapped in a wrap and warmed in a microwave, it is a difficult reality to say that it is good to eat.

 The present invention is manufactured by coating or applying silver nano 40 and fragrance 60 to the body of a wrap 20, which is a kind of packaging paper for packaging food or products made of synthetic resin, to preserve the contents contained for a long time, As regards the environmentally friendly functional wrap 20 that can suppress the occurrence of;

The above techniques are applied to a polystyrene film by adding an antimicrobial masterbatch powder having an antimicrobial effect to the polystyrene powder to form a polystyrene film, thereby inhibiting the growth of bacteria in contact with the polystyrene film to prevent bacteria, fungi, and other viruses. It can be said that the antimicrobial power of the polystyrene film and the antimicrobial power is very weak and the antibacterial and antimicrobial power can be significantly reduced over time.

In contrast, the present invention relates to the coating of silver nano (40) and fragrance (60) on a wrap made of a synthetic resin material, and a nano nano powder (40) which is a strong antimicrobial and bactericidal material. ) And colloidal silver, ie, the silver nano solution diluted with powder and natural fragrance (120). Is as follows.

Currently, silver nano (40) is widely used throughout the industry including medical market, pharmaceutical market, textile, biotechnology, paint, daily necessities, water purifier, cosmetics, deodorant, etc. It is being used on a large scale.

  Silver, the main component of silver nano (40), has been recognized as a precious metal of high value since ancient times, and has been the object of sampling. It is not only valued as a currency but also attracted attention as an important industrial material in modern industry. Production and proportion in many ways.

Silver was mined early in Europe's Mediterranean coast, where silver was produced from the Incas and Aztecs before the discovery of the Americas, and then silver from Peru and Bolivia was introduced into Europe, and its outflow increased steadily from 1520 to 1800. I have declined since a large amount of silver ore was discovered in the western United States in the early 19th century. Currently, the world's major silver producers are Russia (13.8%), Canada (13.5%), Mexico (13%), Peru (13%), United States (11%), Australia (8%), Poland (6%). The country's silver reserves are 17 million tons, and its reserves are about 9.2 million tons. As of 2002, the amount of silver produced in our country is about 5,000 kg, which is 1.2% of the total domestic demand. It's a very small amount.

Characteristics of silver: The color of silver is gray in the case of elegant gray-white metal or powder, specific gravity is 10-12, Mohs hardness is 2.5-3, and melting (80) point is 960.5 ℃.

In particular, the melting point of silver (80) is very important for temperature compensation of high thermometers, which is the standard of scientific and industrial temperature, and silver is the best conductor of metal, and is used comprehensively for contacts and other electronics. Optically, the reflectance for visible light is 90%

It is one of the most excellent metals, such as platinum, and sterling silver does not produce rust even when left in the air or heated. However, the film of the camera should be especially careful because it reacts with sulfur and hydrogen sulfide to make silver emulsified silver.

     In addition, the mechanical properties change depending on the amount of impurities (O₂) contained in the silver, and the hardness of the high-purity silver obtained by thermal annealing is Brinell hardness HBS (10/500) 25-27, tensile strength 12-16kgf / mm2. The cast material had a tensile strength of about 29 kgf / mm 2, an elongation of 48 to 54%, and a recrystallization temperature of 150 ° C.

    In particular, in the case of pure silver, the processed hardened material is softened by recrystallization at normal room temperature and softened softly. The malleability and flexibility are rich after gold.

     Silver's efficacy has been used as a tool to check the imbalance of the body that the person does not feel because the gloss or color changes depending on the condition of the body when worn on the body since ancient times. Fatigue or low rhythm) and Dongbobom said that it is effective in the prevention and treatment of mental disorders and gynecological diseases such as epilepsy and game, and it also acted as a herbal medicine powdered silver. The five chapters are comfortable, the mind and body are stable, and the main body writes that it prolongs morale by lightening the body and lengthening the body.

      Also, when the Black Plague prevailed in the Middle Ages, nobility of the black aristocrats and royals, who had many silverware and silver utensils, did not have black plague, which released silver to the extent that it was able to sterilize the Black Plague bacteria, making it relatively safe from infectious diseases. In the place where the royal family and the state guests were served, silver products were used habitually.

In order to help the understanding of the silver nano 40, the silver nano 40 (Nano silver) extraction method and features of the present invention will be briefly described as follows.

The atomic weight of silver is 107.87 amu and the fact that silver (Ag) is bactericidal has been known for a long time, regardless of east and west. Silver nano (40) was first developed by a biotechnology company, a government-affiliated organization in our country, and was named silver nano (40) as a compound name of the brand name Nano-technology and silver;

  Silver nano (40) is a field of nano-technology, which is an advanced antimicrobial agent that utilizes silver's strong antibacterial and sterilization function and electromagnetic shielding mechanism. Silver nano (40), unlike the traditional antibiotics are not resistant to bacteria, and silver nano (40) has been confirmed to sterilize almost all single cell germs on the ground in a short time.

 Currently, various products based on silver nano (40) consisting of powder and silver nano solution diluted therein are devised and manufactured in real life. This technology called silver nano (40) (銀) refers to the small particle size of nanometer (1 billionth of a meter), that is, 0.000000001m. If you nanonize 1 gram of silver, you can make 10 particles.

* Aged silver (Ag) in the form of ultra-fine particles is a new concept produced by utilizing the excellent efficacy, such as antibacterial deodorization of the various properties of the silver, extending the shelf life of the product.

 Since ancient times, silver has been recognized as a disinfecting substance that not only prevents bacteria but also East and West. The extraction method of silver nano (40) which is currently used injects silver (Ag 99.9%) into distilled water and generates low current at low temperature. After electrolysis of the silver-containing compound, electrophoresis using the + and-poles of each molecule can be used to collect silver (Ag 99.9%) and other physical methods such as liquid reduction and grinding. In order to obtain a stable silver nano (40) (Nano silver) is used a lot of the above electrolysis method.

Silver ions are also used in general sterilization concept machines and disinfectants, and all silver products currently used are silver obtained by decomposition, and the addition amount is very small. The sterilization power of silver varies depending on the product, but a maximum of 99% can be obtained.

 The silver nano (40) of the present invention is a fine particle of 3 to 5 nm silver, which directly acts on harmful bacteria, directly dissolves the cell membranes of harmful bacteria, and disinfects the electron transfer system of the harmful bacteria, thus making sure of excellent antibacterial / agent. It has an average (= 99.9%) (the VIRUS size is about 10 nm).

     The main antimicrobial mechanism of silver nano (40) is to dissolve harmful bacteria cell membranes and work with enzymes in the cells to block the metabolic function of nutrients, that is, the influx and discharge of nutrients, and to stop the respiratory function and production of harmful bacteria, thus stopping the growth of harmful bacteria And destroys regenerating ability to kill harmful bacteria.

     In addition, the silver nano 40 is controlled by the continuous release of antimicrobial force from the microparticles and harmful bacteria, so excellent antimicrobial / bactericidal function.

Therefore, silver nano (40) does not produce resistance and silver nano (40) has a surface reaction is effective and can kill all 99% of the bacteria, and particularly effective in general E. coli or food poisoning.

   In other words, the larger the surface area, the smaller the nanoparticles, the better the bactericidal and antimicrobial activity. strong

Up to MRSA (Methicillin-Resistant Staphylococcus Aureus) can be 99.9% antibacterial and bactericidal.

     Even if silver (Ag) is present in an ionic state or a metal state, it may be referred to as colloidal silver when it is present in a colloidal state by a solvent.

Silver nano (40) is also the best antimicrobial activity of silver nano (40) to maximize the surface area by minimizing particles.

 Silver nano (40), unlike ordinary chemical antimicrobial and chlorine disinfectant, is a pure silver ultra fine particle, so it has an excellent antimicrobial / microbial range (99.9%) even at high temperatures.It is non-toxic and non-irritating to the human body. It has been reported that it cannot live in contact with silver nano 40 for more than 5 minutes.
