Gel Nail Sticker and Manufacturing Process Thereof

A manufacturing process for a gel nail sticker, comprising,

• a. screen printing of a pressure-sensitive adhesive layer:
• a PET release film or release paper is selected as a base film layer having a thickness of 0.05-0.1 mm;
• one pressure-sensitive adhesive layer is printed on a top of the base film layer by screen printing, and dried for 20-50 minutes at room temperature of 25-35° C.;
• b. screen printing of the soft layer:
• the soft layer is a mixture of isophorone and Ethylene glycol monobutyl ether, with a weight ratio of 40:60;
• the soft layer is printed on the pressure-sensitive adhesive layer by screen printing to isolate the pressure-sensitive adhesive layer from ink, and then the soft layer is dried for 80-120 minutes at room temperature of 25-35° C.;
• c. screen printing of the screen printing color layer:
• the color layer is an ink layer;
• according to the requirement of pattern, if the pattern is in one color, only one layer of ink layer is necessary to be printed, and if the pattern is in two colors, two layers are necessary to be printed, and so forth, by screen overprinting;
• in order to ensure saturation of the ink, every color is printed twice by screen printing, and instantly dried at room temperature of 25-35° C.;
• d. screen printing of the shimmering powder layer:
• the shimmering powder layer is a layer of various models of glitter powder, flashing powder, laser powder, camouflage powder, iridescence pigment and pearl powder, or a layer of tinsel or electrochemical aluminium layer, and according to the purpose of design, the shimmering powder layer can be printed under or above the ink layer twice by screen printing, and dried for 20-50 minutes at room temperature of 25-35° C., to increase decoration of products;
• e. screen printing of the crystal gel layer:
• a first crystal gel layer and a second crystal gel layer are layers of epoxide resin glue;
• at room temperature of 25-35° C., epoxide resin glue is printed once by screen printing, and after waiting for 10-15 minutes, the first crystal gel layer is formed, and then epoxide resin glue is printed by screen printing for a second time, and wait for 160-200 minutes to allow the epoxide resin glue to flow naturally to form the second crystal gel layer which is transparent and arc-shaped, and higher in the middle but lower on both sides.
