Description

Screen foam printing method

The present invention relates to screen printing, and more particularly, by applying an adhesive and an aqueous, oil-based foam solution to the OPP (Oriented Poly Propylene), PVC (Poly Vinyl Chloride) laminating coating layer coated on a paper or paper, and then dried naturally The present invention relates to a method for screen foam printing while passing it through a heating roller. In the conventional screen foam printing, screen foam printing is performed by heating the foamed part while screen-printing the aqueous foaming liquid on the synthetic fiber according to the pattern or shape, while passing the synthetic fiber coated with the foaming liquid through a heating roller of 100 ° C. or less.

However, in the conventional screen foam printing, if the synthetic fiber is passed through a heating roller of 100 ° C. or higher, shrinkage occurs in the synthetic fiber, and thus the foaming unit cannot be heated by raising the temperature of the heating roller to 100 ° C. or higher. Was. In addition, screen foam printing on paper was not marketable, and screen foot printing on OPP and PVC laminating coating layer passes the OPP and PVC laminating coating layer coated with foaming liquid through a heating roller to perform screen foam printing. Even if there is no adhesive force between the laminating coating layer and the foaming liquid foaming peeling occurred, this also avoids the production because there is no marketability. Thus, in the past, only water-based foam printing with synthetic fibers was limited. It is an object of the present invention to provide a method that can be more easily screen-foamed printing on paper or OPP, PVC laminating coating layer by improving the conventional synthetic fiber screen foam printing as described above.

In addition, another object of the present invention is the screen printing to apply the adhesive on the OPP, PVC laminating coating layer to apply a water-based, oil-based foam on the screen printing to improve the adhesion between the OPP, PVC laminating layer and the foaming liquid It is to provide a foam printing method.

Hereinafter, the present invention will be described in detail.

The screen foam printing method of the present invention is screen printing to apply the adhesive on a part or the whole of paper or OPP, PVC laminating coating layer, and then screen printing to apply the aqueous, oil-based foam in accordance with the pattern on the pattern ( Color screen printing is also possible) and then dried naturally, and then the dried coating layer is passed through a heating roller as described above to complete the operation while inflating the dried foam part.

As the adhesive used in the screen foam printing method of the present invention, a matte adhesive is preferable, and the natural drying of the aqueous and oily foaming liquid is preferably dried within a range of about 5-20 minutes, and the temperature of the heating roller is 100 ° C-. It is preferable to use it as 200 degreeC. The following process is the process of an exemplary screen foam printing method for carrying out the method of the present invention.

Matte adhesive application process

Screen printing is performed by applying a part or all of the matte adhesive on the OPP or PVC laminating coating layer coated on paper or paper.

Aqueous, Oil-based Foaming Process

As described above, the paper is coated on a part or the whole of the matte adhesive, or the screen printing (color screen printing is also possible) after partially applying an aqueous, oily, foaming solution according to the pattern on the OPP, PVC laminating coating layer. Allow to dry for about 5-20 minutes. However, if the matte adhesive applied to the paper or OPP, PVC laminating coating layer, and the aqueous and oily foaming liquids are naturally dried for 5 minutes or less, it will not be completely dried. It is good.

Foaming process of aqueous and oily foam

As described above, the aqueous and oily foams are coated on paper or OPP, PVC laminating coating layer, and the dried aqueous and oily foam parts are swollen while passing through the heating roller at 100 ° C. to 200 ° C. in a naturally dried state. Printing is complete. However, when the dried coating layer is passed through a heating roller of 100 ° C. or less, complete foaming is not performed. When the dried coating layer is passed through a heating roller of 200 ° C. or more, the coating layer is melted by heat, and thus passes through a heating roller of 100 ° C.-200 ° C. It is good.

For example, according to the above process, color screen printing is also possible in the aqueous or oily foam application process, but this is not necessarily the case, and again, such as the foaming process of the aqueous and oily foam portion after the aqueous and oily foam application process, Color drying with aqueous, oil-based color foaming liquid may be naturally dried, followed by the foaming process of the aqueous, oil-based foaming part, and may be different depending on the manufacturer and other process conditions. In addition, in the screen foam printing method of the present invention as described above, when the matte adhesive applied on the OPP, PVC laminating coating layer coated on the paper is adhered only to the pattern shape according to the pattern shape, the aqueous, oily foam liquid is applied Surfaces other than the above will appear glossy, and when the matte adhesive is applied to the entirety of the coating layer and the work is completed, the surfaces other than the aqueous and oily foaming liquids will appear matt.

It is not only applied to screen foam printing on the paper or OPP, PVC laminating coating layer of the present invention, but the present invention may be applied to leather, artificial leather and the like.

Screen foam printing according to the present invention is mainly for applying to the cosmetic case and liquor case, but is not limited to the cosmetic case and the liquor case.

Hereinafter, an example of the present invention will be described in detail according to an embodiment.

Example 1

After screen-printing the aqueous or foamed liquid onto the pattern or the whole coated paper, the film was naturally dried for 10 minutes and passed through a heating roller at 150 ° C. to swell the aqueous and foamed parts.

Example 2

After screen printing the matte adhesive according to the pattern applied on the OPP laminating coating layer coated on the paper, screen printing (offset printing) of aqueous foaming solution only on it, and then naturally drying for 7 minutes in a natural state. The coating layer was then passed through a 150 ° C. heating roller to swell the aqueous foamed portion to complete the operation. As described above, the surface other than the aqueous and foaming liquids applied was glossy.

Example 3

After screen printing on the whole PVC laminating coating layer coated on paper, and then screen printing applying oil-foaming solution according to the pattern shape on it, and then naturally drying for 7 minutes in the natural state, and then heating the coating layer at 150 ° C. Pass through the roller to swell the oil-based foaming part, color screen printing with oily, foaming liquid on the screen foam printing as above, and then naturally dry for 7 minutes, and then pass the coating layer through the heating roller at 150 ° C. When the oily foam was swelled while the work was completed, the surface other than the oily foam solution was applied was matt.

As described above, the screen foam printing method of the present invention is screen-printed a matte adhesive and an aqueous and oily foaming solution applied on the OPP, PVC laminating coating layer according to the pattern, and passes through a natural drying and heating roller, matte adhesive and aqueous, oily On the other side of the coated foam, the effect of gloss is abrasion, and after the matte adhesive is applied to the entire OPP and PVC laminating coating layer, it is partially dried and screen-printed with aqueous and oil based foam according to the pattern. Passing through the heating roller results in a matt effect on the surface other than the aqueous and oil-based foaming solution applied. In addition, when the case is made of the laminating coating layer of the OPP film, the adhesive is applied by applying a general adhesive to the uniaxial connection of the case and the other side of the case, which is not adhered due to the characteristics of the OPP film, so that the connection portion of the OPP film according to the present invention After coating and drying the matte adhesive, it is easily adhered by passing through a heating roller to apply the common adhesive to the matted connection portion.

As described above, the screen foam printing method of the present invention can be partially or totally screen-printed the matte adhesive according to the pattern of the aqueous and oil-based foam solution applied on the OPP, PVC laminating coating layer coated on paper, glossy, matte Not only can it be manufactured, but there is a method of increasing the adhesiveness between the OPP and PVC laminating coating layer and the aqueous and oily foaming liquid by the matte adhesive.
