0. Ensure the hygiene and safety of those who eat or drink by improving direct or indirect sterilization function.

0. Minimize carcinogenic potential by neutralizing environmental hormones that may occur in the lab itself.

As such, the wrap must have the properties described above to obtain excellent packaging effects, and in particular, the hygiene and safety of people using it can be obtained due to the improvement of safety and functionality described above. It can secure the function as a friendly product.

Conventional wraps were manufactured using polyvinyl chloride (PVC), polyvinylidene chloride, polybutadiene, EVA, LD-PE (low density polyetherene) as raw materials. LD-PE, PVC, polyvinylidene chloride and polybutadiene are used as raw materials for home use, and only PVC is used as a raw material for commercial use.

However, wraps made of PVC raw materials, which are frequently used for commercial use, generate hydrochloric acid and chlorine gas at high temperatures, are not only carcinogenic, but also have stability problems, such as transparency, but they have harmful wastes. PE had a problem of lack of workability and commerciality, such as low strength and poor transparency.

On the other hand, the present invention is to solve the problems of the conventional food packaging wraps as described above and at the same time add a function that can act as a deodorizing action, direct and indirect sterilization, disinfection to the wrap to further prevent food corruption, To preserve food flavors and provide environmentally friendly wraps,

At this time, it was possible to obtain a mixture of wood vinegar solution, which is a charcoal extract in a proportion to the composition used in the preparation of the wrap.

Wood liquor in the above is, as is known, is a liquid called wood blood made by cooling the smoke from the chimney of the kiln when burning charcoal.

This wood vinegar is collected between the charcoal kiln temperature 80 ~ 130 ℃.

This liquid is divided into water solubility and oil solubility. The water solubility is wood vinegar, which can be drunk by humans.

Wood vinegar is an acidic liquid before and after PH3, which has acetic acid as its main ingredient.

In addition, it contains about 200 kinds of active ingredients such as fatty acids such as formic acid (formic acid), propionic acid, alcohol acetone such as methanol and propphenol, formaldehyde and phenol components.

Acetic acid in the total solution is about 3% because the main component is acetic acid is about 50% but wood vinegar is about 90% water.

The wood vinegar contains a lot of active ingredients, but also contains a very small amount of harmful components, these harmful substances are removed by milk purification.

Wood vinegar is a colorless or slightly colored transparent liquid, characterized by strong permeability and absorption into the body of plants and animals.

The undiluted liquor is quite strong and irritates the nose. It has a characteristic burning smell, but acetic acid, methanol, formaldehyde, etc., and it is known that smoked products such as ham and sausage are made using this smell.

Neutralizes fishy fish and other fishy smells of wood vinegar.

The present invention solves the problems of the conventional wrap film by adding and mixing together the wood vinegar solution at a predetermined ratio in the process of melting and transporting the raw material used in the film production, such as wrap, to solve the problems of the conventional wrap film, etc. Its main purpose is to further improve the health and safety of users who consume or consume the food packaged and stored by the lab by improving its function and by obtaining a bactericidal effect.

Another object of the present invention is to improve the safety of the product and the user by neutralizing carcinogens, such as environmental hormones that may be generated when the hot food is stored because the wood vinegar is contained in the film.

Another object of the present invention is to significantly expand the scope of application by introducing a suitable amount of the mixture consisting of wood vinegar solution in the production of vinyl film paper related to the packaging or processing of food.

In order to achieve the above object, the present invention provides a method for producing a non-toxic film based on the following wood vinegar.
