The leaves and stems of the moth are collected in spring, and the fruits are preferably collected from late summer to early autumn.

The leaf, stem, and fruit of the above-mentioned motam are washed.

The leaves, stems, and fruits of the above-mentioned mamma washed are dried at room temperature.

 The leaves, stems, and fruits of the well-dried moth are pulverized with a pulverizer.

It is preferable that the leaves, stems, and fruits of the moths are composed of fine powder.

[Solubility of polyethylene resin: S200]

Polyethylene resin is melted with a heater.

The polyethylene resin is preferably composed of a low density polyethylene (LDEP) resin.

[Step of adding an additive to a polyethylene resin solution and melting with a heater: S300]

Menthol or a peppermint additive is added to the melted polyethylene resin solution for halitosis inhibition and volatilization.

Then, the polyethylene resin solution to which the additive has been added is heated by a heater, and the temperature of heating by the heater is maintained at 145 to 155 占 폚.

When menthol or peppermint, which is an additive, is added to produce a film together with moras powder, when the fresh product is stored in the film, the smell from the fresh product is blocked by source, thereby always generating fresh smell of menthol and peppermint flavor, So that a more fresh feeling can be felt.

[Melt mixing step of polyethylene resin and moth powder with a heater: S400]

Powdered moras are added to molten polyethylene resin.

It is also preferable to weigh 90 to 110 g of the above-mentioned morom powder with 21 to 29 kg of the molten polyethylene resin by metering using a mortar.

Then, powdered morom mixed with polyethylene resin is mixed with a mixer.

It is preferable to mix the powdered phosphorus with the polyethylene resin to be mixed by heating with a heater.

In addition, it is preferable that the temperature for mixing the molten powder with the melted polyethylene resin and heating it with a heater is maintained at 145 to 155 ° C.

The polyethylene resin is preferably a low density polyethylene (LDEP) resin.

[Experimental Example]

The film to which the moras were added was prepared by extruding 100 g of moras powder into 25 kg of the molten low density polyethylene resin while heating and mixing at 150 캜 into a film having a thickness of 40 탆 and a width of 45 cm.

In order to check with the film, a control film was prepared by extruding a low-density polyethylene resin into a film having a thickness of 40 m and a width of 45 cm.

The oxygen permeability and antimicrobial activity of the film of the present invention and the control film were tested as follows.

[Experimental Example of Oxygen Permeability]

As shown in the test report of FIG. 2, the oxygen permeability of the film of the present invention and the control film was repeated three times with an oxygen permeation meter (Gas Transmission Rate Model BT-3, Toyoseki Co, Japan) Held at 23 < 0 > C.

The pressure of the atmospheric pressure gauge was fixed at 138 kPa, and the flow rate of oxygen was maintained at 20 cc / min. As the carrier gas of the permeated oxygen, nitrogen was used.

As shown in the test report of Table 1 below, the oxygen permeability for the control film was about 4,200 cc / day 占 퐉 2.

The oxygen permeability of the film of the present invention was found to be about 4,000 cc / day 占 m2.

As described above, the film of the present invention to which morom is added has an oxygen permeation inhibiting effect of about 5%.

In the case of morem, the addition amount can be increased, and a higher oxygen permeation inhibiting effect can be expected in producing the film.

Therefore, when the film of the present invention is used as a packaging material, oxygen permeation of fresh food packaged in the packaging material is suppressed to the outside of the packaging material to maintain the freshness of the fresh food.

[Experimental Example of Antimicrobial Activity]

The strains used for moramine-added films are E.coil, P. Aeruginosa, and B. cereus. Bacteria inoculated into the solid medium do not grow in the presence of antimicrobial agents

Therefore, microdisks containing antimicrobial substances were placed on the solid medium inoculated with the bacteria to observe the growth of bacteria around the discs.

When a compound having an antimicrobial effect was present, a clear zone in which the growth of the bacteria was inhibited was observed.

The higher the concentration of the antimicrobial compound or the stronger the effect, the greater the diameter of the clear zone.

Using this principle, we observed the diameter of the clear zone by immersing leaf, stem, and fruit extract of moth, in a micro disc, and placing it in a solid medium.

As a result, the micro discs with the leaf, stem and fruit extract of Moresum were E. coli, Ps.aeruginosa, and B. cereus. It was observed that the diameter of the clear zone did not increase in the solid medium.

Therefore, the film to which the motam of the present invention is added contains antimicrobial activity which suppresses the microbial activity, so that when the film containing the motam is used as a packaging material, the activity of the microorganism is inhibited against the fresh food packed in the packaging material, The nephrin food can be stored for a longer period of time in the packaging material.

Meanwhile, in the method for producing a film of the present invention, the polyethylene resin and the mora powder are added to the melted polyethylene resin in addition to the moram powder in the melt mixing step (S400) using a heater to form a nano- Loam powder, and silver nano were added to the melted polyethylene resin to add molybdenum powder, nanotized white clay, loess powder and silver nano to the melted polyethylene resin. To have more antibacterial properties

In addition to antimicrobial properties of white clay, loess, and silver nano, which are antimicrobial in antimicrobial activity to inhibit the biological activity of motam, when freshly packed films containing morom, nanoized clay, loess and silver nano are used as packaging materials, The present invention is intended to inhibit the activity of microorganisms and store the fresh food in the packaging material so that the fresh food can be stored for a longer period without any deterioration.
