Surface craftsmanship of spice tin

Due to the thin ink layer of offset printing products, it is easy to cause insufficient ink saturation, resulting in poor overall gloss effect of the printed products. Therefore, film coating or polishing technology is used to improve the surface gloss of the printed products, thereby increasing the brightness of the ink layer of the printed products. At the same time, it provides an effective protection for the spice tin, so that the color can not fall off due to friction during post printing processing and storage and packaging. The plastic film used for laminating is transparent, has high glossiness, and is inexpensive. Due to the difficulty in recycling and regenerating paper after lamination, which is non degradable and prone to white pollution, traditional instant lamination adhesive materials will be replaced by high-quality environmentally friendly new adhesives. Not only can it enhance surface brightness and protect printed graphics and text, but it also does not affect the recycling and reuse of paper, saving resources and protecting the environment. Therefore, the surface technology widely used in spice tin packaging is applied in the packaging industry. Its process characteristics are: on the surface of ordinary offset paper or matte film, screen printing technology is used to coat the paper pattern, so that the coating area forms a strong contrast with the matte or glossy surface, achieving the finishing touch effect on the graphics and text that need to be emphasized: local crystal convex characters, rainbow sanding, etc. The convex process mainly uses pressure to transfer the pattern onto the surface of the material, and produces a relief effect through the convex process.
