Gel nail sticker and manufacturing process thereof

摘要

A gel nail sticker includes a base film layer, and a pressure-sensitive adhesive layer, wherein the base film layer is a PET release film or release paper, and the pressure-sensitive adhesive layer is bonded to the bottom of a soft layer and connected with the base film layer; the soft layer is printed with at least one layer of screen printing color layer or shimmering powder layer by screen printing; a first crystal gel layer covers on the surface of the shimmering powder layer or the screen printing color layer, and a second crystal gel layer envelops the first crystal gel layer, the shimmering powder layer and the screen printing color layer, and is bonded to the soft layer and the pressure-sensitive adhesive layer. A manufacturing process for the gel nail sticker, includes screen printing of the various layers.

主权项

1. A manufacturing process for a gel nail sticker, comprising,
a. screen printing of a pressure-sensitive adhesive layer, wherein a PET release film or release paper is selected as a base film layer having a thickness of 0.05-0.1 mm and the 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 a soft layer, wherein 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 one or more screen printing color layers on said soft layer, wherein each color layer is an ink layer, with the number of ink layers being equal to the number of colors in a pattern for the gel nail sticker, and each color layer being printed by screen overprinting while, 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 a shimmering powder layer, wherein 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 an electrochemical aluminium layer, and, for design purposes, the shimmering powder layer being printed under or above the one or more screen printing color layers twice by screen printing, and dried for 20-50 minutes at room temperature of 25-35° C., to increase a level of decoration; e. screen printing of a crystal gel layer including a first crystal gel layer and a second crystal gel layer of epoxide resin glue wherein, 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, with the epoxide resin glue being given 160-200 minutes 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, said first crystal gel layer covering said one or more screen printing color layers or said shimmering powder layer and said second crystal gel layer enveloping said first crystal gel layer, said shimmering powder layer, and said one or more screen printing color layers.
