Several common packaging post-press processes

A good product must be popular, and a good product with beautiful packaging will sell well. Packaging itself doesn't have much use value, but it is a means to enhance the value of goods. Therefore, the importance of product packaging cannot be ignored. For product packaging, design is important, and packaging is even more important after press. Today, Biyin Bazaar will talk about several common packaging post-press processes. 1. Lamination. Lamination is a transparent plastic film that is laminated to the surface of the printed matter through hot pressing to be smoother and brighter, and the color of the picture and text is more vivid, and it also plays a waterproof and anti-fouling role, which can be divided into two processing processes, such as surface processing and molding processing, hot stamping, glazing and waxing; Molding processing technology. Lamination not only makes the surface of the printed matter wear-resistant, bending-resistant, and chemical-resistant. However, because plastic film is non-degradable, it is difficult to recycle and easily cause pollution. Therefore, in the case that glazing can be replaced, the plastic laminating process should be used with caution. Second, hot stamping. Hot stamping, also known as hot press printing, is to make the pattern or text that needs to be hot stamped into a convex version, and with the help of a certain pressure and temperature, a variety of aluminum foil sheets are printed on the substrate, showing a strong metallic light, so that the product has a high-grade texture. At the same time, because aluminum foil has excellent physical and chemical properties, it can play a role in protecting the printed matter. Therefore, the hot stamping process is widely used in modern packaging printing. 3. Glazing and waxing. Varnishing is to coat or spray a layer of colorless transparent paint on the surface of the printed matter to brush the gloss of the product, and play a waterproof and oil-proof role on the surface of the packaging. The product is bright and bright, and plays a good barrier role. To form a glossy film to increase the wax on the wrapper, hot-melt wax is applied to the wrapping paper. Fourth, concave and convex embossing. Embossing is a special technique for decorating the surface of printed matter. It is the use of concave and convex molds, under a certain pressure, to make the substrate of the printed matter plastically deformed, and then the surface of the printed matter is artistically processed. The embossed various convex graphics and patterns show different shades of patterns, with an obvious sense of relief, which increases the three-dimensional sense and artistic appeal of the print. 5. Die-cutting indentation. Die-cutting indentation is also known as die-cutting forming, buckle knife, etc. When the packaging printing carton needs to be cut into a certain shape, it can be completed by die-cutting and indentation process. Die-cutting is a process in which the steel blades are arranged into molds (or carved into molds with steel plates), frames, etc., and the paper is rolled and cut into a certain shape on the die-cutting machine. Indentation is the use of steel wire, which is embossed on a piece of paper to create marks or leave groove marks for bending. Sixth, bronzing. Gold, silver, laser gold, bronze gold, etc., generally after glue before bronzing or silver; There should be a counterpoint line out of the film; The effect of hot stamping is varied, but according to the base material of hot stamping, it is also classified, divided into hot stamping paper, hot flannel cloth, hot plastic, etc. 7. Local UV process. It is a silk screen printing process, which improves the dazzling effect of the printed product by partially coating the graphics and texts on the surface of the carton. 8. Freezing snowflakes. The freezing point snowflake effect is an effect with fine sand and delicate feel formed on the surface of the printed product after the ink silk screen is wrinkled by ultraviolet light and cured by UV light after being wrinkled by ultraviolet light and cured by UV light. Because of its effect on the surface of the printed product like a thin layer of snow or ice, it is commonly known in the industry as "snowflake" (larger pattern) or "freezing point" (smaller pattern). This process has the characteristics of fine pattern, strong three-dimensional sense and luxurious elegance visually, and is widely used in tobacco and wine boxes, wall calendars, gift box packaging or other exquisite prints. The above nine points are the most common packaging post-press processes on the market now, and I believe this article has given you a general understanding of packaging post-press.
