What production processes are generally used for cosmetic packaging boxes?
China's cosmetic market is the largest emerging market in the world, and the demand for cosmetic packaging is also growing.
01. Glue process
It is a surface processing technology after printing, also known as printing glue, printing laminating or post-printing film, which refers to the use of a laminating machine to cover a layer of 0.012-0.02mm thick transparent plastic film on the surface of the printed product. , and form a paper-plastic product processing technology.
02. Oiling process (varnish, dumb oil, UV varnish)
It is to coat (or spray, print) a layer of colorless and transparent paint (glazing oil) on the surface of the printed matter. After leveling, drying and calendering, a thin and uniform transparent and bright layer is formed on the surface of the printed matter. Glazing includes overall glazing, partial glazing, glossy glazing, matte (matte) glazing and special paint glazing.
03. Polishing process
The glazing process is carried out on two units of varnish coating and hot pressing. The printed matter is first coated with varnish on an ordinary glazing machine, and after drying, it is hot-pressed by the stainless steel belt of the calender. After cooling and peeling, the surface of the printed matter forms a mirror reflection effect to obtain high gloss.
04. Reverse UV process
Reverse glazing is relative to traditional spot glazing. It can make the high-gloss effect of mirror surface and the non-high-gloss effect of matt surface or pockmark surface exist on the same printed product at the same time, forming a stronger contrast in brightness, so that the glazing can achieve a better effect. At the same time, because the non-high-light parts are printed by offset printing, the overprinting is very accurate, and the printing accuracy of the graphics and texts in the high-light parts is also guaranteed.
05. Embossing process (refractive, deep embossing, full version)
A post-processing process in which the paper is pressed against the plate cylinder and the impression cylinder, and the product has various lines (the surface of the product has uneven lines of various shapes).
06. Hot bronzing process
It is a process in which metal foil is transferred to the surface of printed matter or other items by hot pressing to increase the decorative effect.
07. Cold bronzing process
It is a process of transferring metal foil to the surface of printed matter or other items without heating, only through the force of pressure and bonding and peeling, and has a decorative effect.
08. Gold rubbing process
It is the process of printing the writing or pattern with a certain paste, applying golden yellow metal powder while it is still wet and letting it adhere, and then wiping off the excess powder to reveal the golden text or pattern.
09 Gold Rolling Process
It is a process of applying the paste on the edges of various books, then applying the golden yellow metal powder while it is still wet and letting it adhere, revealing the golden text or pattern.
10. Strike craftsmanship (knock convex, concave, braille, embossed)
It is a special process technology in the surface finishing of printed matter. It is suitable for negative (concave) and positive (convex) molds, and mechanically exerts pressure that exceeds the elastic limit of the printed matter substrate to perform artistic processing on the printed matter surface. Enhance the three-dimensional sense of printed graphics.
11. Silk screen process
Including UV frosting, UV ice flower, UV foaming, UV wrinkle, UV embossing, UV refraction, UV gemstone, UV light fixing ink, UV varnish and other UV processes.
On the surface of the substrate with metallic mirror luster, UV ink is printed on the surface by screen printing technology. After being treated by ultraviolet drying equipment, a unique visual effect is produced, which is elegant, solemn and luxurious. The products are mainly used in high-end, exquisite and unique packaging and printing of tobacco, wine, cosmetics, health care products, food, medicine, etc.
12. Die cutting process
It is a process in which steel knives are arranged into a mold (or a steel plate is carved into a mold) frame, and the paper is cut into a certain shape on a die-cutting machine.
13. Punching process
The diameter of the hole is large and the number of holes is small. There are two methods: manual and machine. Each punching action can penetrate more than one substrate with a certain thickness.
14. Indentation process
It is a processing technology that uses steel wires to emboss marks on the paper, or leave groove marks for bending.
