1、 Die cutting indentation: the most commonly used process for packaging printing is to use a die cutter to fibre drum The molding process of die-cutting the required pattern or cut into the desired shape according to product design requirements.

2、 Film coating: Due to paperboard drum The ink layer of offset printing is relatively thin, which can easily cause insufficient ink saturation,fibre drum The overall gloss effect is often poor. To improve the surface gloss of printed products, laminating or glazing processes are used to enhance the brightness of the ink layer in paper barrel printing, while also providing an effective layer of protection for paper barrel packaging, so that the color of paper barrel packaging can be processed after printing and stored and packaged without falling off due to friction. 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.

3、 Polishing: Not only can it enhance the surface brightness of paper can packaging 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, it is applied to Paper bucket packaging The surface craftsmanship.

4、 The convex process mainly uses the method of pressure to transfer the pattern and apply pressure to the surface of the material. By using the convex process to create a relief effect,Paper bucket packaging More aesthetically pleasing, with a more distinct theme and richer tactile experience.

5、 The UV technology is applied in the paper barrel packaging industry, and its process characteristics are: on the surface of ordinary offset paper or BOPP 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 UV, crystal raised characters, rainbow, sanding, etc.

6、 Hot stamping:paperboard drum In the fierce market competition, in order to increase the added value of products and more effectively carry out packaging anti-counterfeiting, more and more packaging paper drums are adopting hot stamping technology.Hot stamping foil The main method is to use heating and pressure to transfer patterns or text onto the surface of the hot stamping material. The characteristics of hot stamping: clear and beautiful patterns, diverse and dazzling colors. Hot stamping on cardboard barrels can highlight the design theme and beautify the product.
