Eight kinds of common packaging box surface process

With the rapid development of society, people's requirements for packaging are getting higher and higher, not only requiring high-grade and exquisite packaging boxes, but also requiring them to have certain environmental performance and individual appearance. Post-press processing not only enhances the artistic effect and added value of packaging, but also meets the needs of consumers at different levels, and is an important link to ensure the quality of packaging boxes. In this paper, Xiaobian will share with you the common eight kinds of packaging box surface pattern technology, for reference.

01

Laminated film

Also known as "over-plastic", "laminating" and "laminating", laminating is a transparent plastic film that is laminated to the surface of printed matter by hot pressing, which not only plays a role in increasing gloss, making the color of pictures and texts more bright, but also plays a role in waterproof and anti-fouling. It is commonly used in post-press processing of high-quality cartons, cartons and other packaging.

02

Hot stamping

Commonly known as "hot stamping", is to make the pattern or text that needs to be hot stamped into a convex version, with a certain pressure and temperature, transfer the hot stamping foil to the substrate, showing a strong metal light, so that the product has a high-end texture. At the same time, because the aluminum foil has excellent physical and chemical properties, it can protect the printed matter.

03

Glow

Polishing is a colorless transparent coating on the surface of the printed matter. After leveling, drying, calendering and curing, a thin and uniform transparent oil layer is formed on the surface of the printed matter, thus enhancing the smoothness of the surface of the printed matter and protecting the printed picture and text.

04

Embossing

Embossing is a special technique for finishing the surface of printed matter. It is the use of concave-convex mold, under a certain pressure, so that the printing substrate plastic deformation, and then on the surface of the print art processing. A variety of embossed convex graphics and patterns show different shades of patterns, with a clear sense of relief, increasing the three-dimensional sense of print and artistic appeal.

05

Die-cutting indentation

Die-cutting indentation is also called press-cutting forming, buckle knife, etc. When the packaging needs to be cut into a certain shape, it can be completed by die-cutting indentation process. Die-cutting is the process of rolling paper into a certain shape on a die-cutting machine by using a steel knife to form a die (or engraving a steel plate into a die), a frame, etc. The hollowed-out part of the main display surface in the middle is obtained by die-cutting process and becomes a personalized finishing process in the whole package. Indentation is the use of steel wire, through the pressure on the paper to press out the marks or left for bending groove marks.

06

Local UV process

Local UV process can be realized by screen printing or flexo printing process, which is a kind of surface finishing process of printed matter. UV varnish is partially coated on the surface of packaging to enhance the colorful effect of printed matter. Compared with the surrounding patterns, the glashing pattern is bright, bright and three-dimensional, and can produce unique artistic effect.

07

Reverse Sanding

The reverse frosting process needs to be completed by several special base oil or light oil treatment. Some people also call it reverse glazing process and regard it as a new process of partial glazing. The process is to print a layer of special base oil on the local area that does not need to highlight high brightness by offset printing line (or offline) after the printed matter is printed according to the normal color sequence, and UV varnish is coated on the surface of the entire printed matter in a full plate manner after the base oil is completely dried.

In this way, a cohesive reaction occurs in the area where the UV varnish contacts the base oil to form a small granular ink film, forming a matte or frosted surface, while a high-gloss mirror surface is formed in the UV glazing area without printing the base oil. The surface of the print eventually forms local high gloss and local matte low gloss areas. The two completely different gloss effects achieve a high contrast effect of the local image, embellishing and highlighting the graphic with a glossy mirror.

08

freezing point snowflake

Freezing point snowflake effect is an effect of fine sand feeling and delicate hand feeling formed on the surface of printed matter after UV irradiation, wrinkling and UV curing on gold cardboard, silver cardboard, laser cardboard, PVC and other substrates. Because of its effect on the surface of the printed matter, such as a thin layer of snow or ice, the industry is commonly known as "snowflake" (larger pattern) or "freezing point" (smaller pattern).
