Coated paper, also known as printing coated paper, is made by coating a layer of white paste on base paper and calendering it. Such paper has a glossy surface, high whiteness, low stretchability, and good ink absorption and acceptance. It is mainly used to print the covers and illustrations of high-end books and periodicals, color pictures, various exquisite product advertisements, samples, product packaging boxes, trademarks, etc.
Uncoated paper is an ideal material for making high-end packaging boxes. Its good hand feel, perfect color, dot transfer conditions, stiffness, and surface strength are reasons for the designer’s choice. According to the requirements of different packaging boxes, designers can make design choices for various cardboards.
(1) White Uncoated Paper
The characteristics of white uncoated paper are high whiteness and soft gloss, elegant and noble, good dot transfer during printing, high level, color restoration, and delicate hand feeling. Designers often use white cardboard in high-end products such as gift boxes, cosmetic boxes, wine boxes, and hang tags.
(2) Glass Paper
Glasspaper is a kind of white uncoated paper produced by vitrifying the surface of white cardboard. The surface gloss of this paper is very high, and the hand feels smooth. Its visual effect is better than that of cardboard and coated paper after UV coating. The degree is still high, and the products made with this kind of cardboard are very bright and eye-catching.

Board paper is a kind of laminated structure paper. Its basis weight is 220g/m2, 240g/m2, 250g/m2…400g/m2,450g/m2, with a wide range and the largest choice among various materials. This kind of paper has a certain degree of stiffness and surface strength. Moreover, Because of the painted white paper’s surface coating, the printing ink is not easy to penetrate. The amount is small. The printing image color and dot transfer are good. But the disadvantage is that the flatness is poor, and the printing speed is slow; another disadvantage is that the hand feel is rougher than the cardboard.
