Description

Epoxy sticker and manufacturing method thereof

The present invention relates to an epoxy sticker and a method of manufacturing the same to improve the commerciality by expressing a partial three-dimensional effect by the epoxy (epoxy) resin injected into the sticker.

More specifically, when the epoxy resin is injected into the printing portion of the printing film layer bonded on the release paper (paper material, PET, PVC, PP, etc.), the epoxy having the cohesive force and the spreadability due to the surface tension, The present invention relates to an epoxy sticker and a method of manufacturing the same, in which a mold release agent (silicon, wax, paraffin, etc.) is injected and cured only in a region except for a coated portion, thereby expressing a three-dimensional effect by forming partial irregularities on the sticker. .

In general, offset printing or silkscreen printing is mainly used to produce stickers. Offset printing is one of the indirect printing methods, and there are two methods of transferring the ink on the plate to the paper: direct printing, which transfers the ink directly to the paper from the plate surface, and indirect printing, which transfers the ink on the rubber blanket to the paper again. Classified as The convex plate, the concave plate, and the plate are also offset printed, but the flat plate is mainly offset printed. In general, offset printing means plate printing.

Offset printing was first applied to metals and glass that would not be possible with direct printing. Its feature is the use of rubber blankets, so it can be clearly printed even on rough paper, its printing strength is stronger than that of direct printing, and it is easy to find that the letters and images on the plate are different from the print.

Silk screen printing is a printing method that transfers ink to paper by passing ink through a mesh hole using a plate composed of wires on a surface of a wooden frame. Conventionally, silk mesh is used, so it is called silkscreen printing. Recently, nylon, tetron, stainless steel, and mesh are used, so it is called screen printing.

The screen printing machine has a flat printing machine and a curved printing machine. The flat printing machine prints paper, plastic, cellophane, printed wiring board, and the like, and the curved printing machine prints on bottles, cups, and the like.

In the case of manufacturing a protruding sticker in the related art, an epoxy resin solution is injected into a patterned surface of a printing film on which a pattern of a sticker is printed and manufactured by a manual method of drying. As a result, the degree of protrusion of the finished sticker is different from each other, resulting in inferiority in product uniformity, a rise in product cost due to labor costs for the manufacture of protrusion stickers, and the inability to mass-produce stickers in a short time.

On the other hand, there has been disclosed a method that can be mass-produced by silk printing with UV liquid, but the production of the protruding sticker in the natural drying phase due to the low viscosity of the UV liquid. For this reason, it is required to work difficult to pass through a device capable of irradiating ultraviolet rays to harden within a short time before the UV liquid flows. In addition, when using a high-viscosity UV solution can solve the above problems, but the raw material is expensive, the raw material cost is increased, there is a problem that the price competitiveness of the product is lowered.

An upper layer 4 formed with an adhesive layer 2 on the bottom surface and bonded to the release paper 1;

A printing film layer 3 adhered to the upper paper 4, the printing portion being formed on the upper surface by offset printing or screen printing,

After scanning on the printing film layer 3, it comprises an epoxy layer 5 which is dried and cured.

In the process of manufacturing the epoxy sticker, after forming the printing portion 3a on the above-described printing film layer 3, the outer portion of the printing portion 3a is partially cut by thomson or heat cutting. At this time, the printing portion 3a of the partially cut printing film layer 3 maintains a state of being bonded on the release paper 1. After peeling and separating the print film layer 3 corresponding to the margin except the cut printing part 3a from the release paper 1, the epoxy resin is injected onto the printing part 3a and dried.

As described above, when partially injecting an epoxy resin onto the printing portion 3a to produce an epoxy sticker, the spreadability of the epoxy resin is naturally applied to the cut edge of the release paper 1 (ie epoxy Resin is layered on all areas of the upper surface of the printing part, resulting in a flat texture). As such, the three-dimensional effect of the sticker is inferior, and thus, purchasing power is lowered because it does not cause interest or curiosity of consumers.

Embodiment of the present invention, as the epoxy is partially injected to the printing portion of the printing film layer to be detachably bonded on the release paper to cure, the epoxy to express the three-dimensional effect by the uneven portion formed in the sticker It relates to a sticker and a method of manufacturing the same.
