Color box packaging and printing generally require some special processing, such as gloss glue, matt glue, varnish, etc., generally based on the following factors:

1. Protect the color and luster of the printed matter. The face paper printed in color box packaging is printed with ink. Under the action of ultraviolet rays, the printed matter will easily fade;

2. Waterproof function. Since the color box packaging is all paper products, in order to prevent it from decay in contact with water; to enhance the brightness of the product, through a special surface treatment, the product has a soft and rough texture, which is more attractive to consumers.

Color box packaging box surface treatment process:

Film

The advantages of the film are waterproof, storage-resistant, and beautiful. Laminating glue refers to a glue that combines bopp film on paper. At present, there are two ways of touching printed packaging products in China, one is water-based laminating and oil-based laminating, and now the main method is water-based laminating , The water-based coating method is based on the concept of environmental protection, and its effect is slightly worse than that of the oil-based coating.

There are also two types of packaging printed materials due to materials:

1. Glossy film (bright film), the bright film itself is relatively bright, the surface of the color box packaging box is shiny and shiny after the bright film is covered.

2. Dumb film, which has a matte surface; matte matte-like matte surface after coating.

Bronzing

At present, the hot stamping method of color box packaging box is electrochemical aluminum hot stamping foil, which mainly adopts heating and pressurizing methods to transfer the text of the copy box to the surface of the printed packaging paper to be hot stamped. The colors are gold, silver, green, and blue. , Laser, etc. are called bronzing.

Hot stamping is characterized by clear patterns, beautiful appearance, bright and eye-catching colors, and wear resistance. In the printing of cigarette packages, the hot stamping process accounts for more than 85%, and it is also widely used in commercial packaging production. It can be used to add finishing touches, highlight themes, show honor, etc., especially for trademarks, logos, corporate names and other places that need special highlighting.

Hit bump

Bumping is an important process in the packaging post-printing process, and it is an imprinting method without printing ink. When pressing the concave and convex, a set of concave and convex stencils corresponding to the yin and yang of the graphics and text are used, and the substrate is placed in between, and the embossed concave and convex graphics and text are pressed out by applying greater pressure. This method is mostly used in the post-printing processing of printed matter and color box packaging, such as the decoration of packaging boxes, trademarks, cigarette packets, New Year cards, bottle labels, etc., to obtain a vivid and beautiful three-dimensional effect. Proper use of embossing process can increase the layering of printed patterns and play a finishing touch to packaging products. This process has low cost in post-press surface treatment.

UV matte

UV frosting is a post-printing process that uses ultraviolet light to dry and cure the ink. It requires UV ink containing a photosensitizer and a UV curing lamp. The UV process transfers the pattern and text to the surface of the UV printed packaging paper. Make it bright and special, especially for partial printing positions such as trademarks, logos, and company names.
