The manufacturing step S110 is a step of manufacturing the second layer 200. The polymer forming the second layer 200 is formed into a single state selected from a liquid state or a semi-solid state at a temperature of 30 to 200 ° C .

Preferably, the polymer may be prepared in a liquid or semi-solid state at a temperature of 100 to 180 DEG C, but is not limited thereto.

If the temperature for producing the polymer is less than 30 ° C, it takes a long time to produce the polymer in a liquid or semi-solid state. If the temperature is more than 200 ° C, There is a disadvantage in that the polymer is not easily laminated in step S120.

Next, a first laminating step (S120) of laminating the polymer through the manufacturing step (S110) to one side of the release paper may be performed.

The release paper may be made of one or more selected from among polyethylene (PE), polypropylene (PP), fluorine-based release paper, polyethylene terephthalate (PET), polyurethane (PU), polyvinyl chloride (PVC), and thermoplastic polyurethane have.

Next, a method of laminating the first layer 100 made of at least one selected from the group consisting of cloth, PU (polyurethane) and liquid silicone on the surface of the laminated sheet which has undergone the first lamination step (S120) A secondary laminating step (S130) may be performed.

The lamination method to be performed in the first and second lamination steps S120 and S130 may be knife coating, reverse roll coating, roll coating, calendar coating, curtain coating, extrusion coating, cast coating, spray coating, Coating, air knife coating, inverted rod coating or engraved roll coating or the like may be carried out.

Next, the laminated sheet passed through the second lamination step (S130) is passed through between the rollers provided with a plurality of laminated sheets, so that one side and the other side of the laminated sheet passing through the second lamination step (S130) are flat (S140) can be performed.

The distance between the rollers used in the pressing step (S140) may be 0.001 to 5 mm, and the speed at which the laminated sheet passes between the rollers may be 1 to 100 mm / s.

When the distance between the rollers is less than 0.001 mm, the thickness of the sheet including the finally produced laminated structure is made thin and the first layer 100 is not easily fixed to the laminated sheet If it is formed to be 5 mm or more, there is a disadvantage that the thickness of the laminated sheet is made thick and the manufacturing cost is increased.

Further, when the speed at which the laminated sheet passes between the rollers is less than 1 mm / s, the passing speed becomes too slow, which requires a long manufacturing time. When the laminated sheet passes at a speed of 100 mm / s or more, The upper and lower sides of the laminated sheet can not be made flat.

Thus, by stacking the layers in the reverse order of the conventional laminating process, the interface is formed unevenly so that the uniform physical properties of the second layer 200 can be maintained and the quality can be improved.

Next, a drying step (S150) of drying the laminated sheet having undergone the pressing step (S140) by a dryer may be performed.

The drying temperature in the drying step (S150) may be from 30 to 100 ° C for 10 to 600 seconds, but is not limited thereto.

If the drying temperature is lower than 30 ° C., the drying temperature is too low to take a long drying time. If the drying temperature is 100 ° C. or higher, the laminated structure is finally manufactured at a high temperature There is a disadvantage in that the cross section of the sheet is not uniformly dried.

If the drying time is less than 10 seconds, drying of the laminated sheet is not easily performed due to a short drying time. If the drying time is longer than 600 seconds, There is a disadvantage of lengthening.

Next, a release paper removing step (S160) for removing the release paper provided on the laminated sheet after the drying step (S150) may be performed.

It is advantageous that the third laminating step (S170) to be described later in the second layer 200 in a liquid or semi-solid state can be easily performed by the release paper removing step S160.

Next, a third lamination step (S170) of stacking the third layer (300) including a plurality of micro needles (302) on the release paper removing surface of the laminated sheet after the release paper removing step (S160) is performed .

That is, the third layer 300 may be provided on one side of the second layer 200 by the third stacking step S160.

A pressure sensitive adhesive may be used to adhere the other side of the third layer 300 to one side of the second layer 200. The pressure sensitive adhesive may be silicone, polyurethane, hyaluronic acid, a physical adhesive Gelco), polyacrylic, ethylcellulose, hydroxymethylcellulose, ethylene vinyl acetate and polyisobutylene can be used.

It is obvious that the third layer 300 can be adhered using a known adhesive method.

The present invention relates to a sheet including a laminated structure, and is an invention applicable to industries related to skin care such as a mask sheet, a chin mask sheet and the like.
