We are a custom rigid box manufacturer and know better about the paper materials used in gift box packaging. Today we will talk about coated paper, the most normal wrapping paper used in making customized paper gift boxes.
Coated paper, also known as coated printing paper, is called art paper in Hong Kong and other regions. It is an advanced printing paper made from base paper coated white paint. Mainly used for printing high-end books and magazine covers and illustrations, color pictures, a variety of exquisite product advertisements, samples, product paper gift packaging, trademarks, and so on.
Coated paper is a flat sheet, with a size of 787×1092mm, 880×1230mm, and a basis weight of 70-250 g/m2. Coated paper has single-sided coated paper, double-sided coated paper, matt-coated paper, and coated copper coated paper. The quality is divided into A, B, and C three levers. The main raw materials of coated paper are copperplate paper and coatings. The requirements for copperplate paper are uniform thickness, low elasticity, high strength, and good water resistance. The paper surface is not allowed to have paper spots such as spots, wrinkles, holes, etc. The coating used for coating is composed of high-quality white pigments (such as kaolin, barium sulfate, etc.), adhesives (such as polyvinyl alcohol, casein, etc.), and auxiliary additives. The paint with high liquidity and high solid content is thinly and evenly coated on the base paper by a coater, then dried, rolled into a roll on a reel, and then sent to a super calender for pressing. Light finishing, final cut, paper selection, packing.
Coated paper is characterized by a very smooth and smooth paper surface, high smoothness, and good gloss. Because the whiteness of the paint used is more than 90%, the particles are very fine, and it is calendered by a supercalender, the smoothness of the coated paper is generally 600 to 1000 s. At the same time, the paint was evenly distributed on the surface of the paper to show a pleasant white color. The requirements for coated paper have higher coating strength, the coating is thin and uniform, and there are no air bubbles. The amount of adhesive in the coating is appropriate to prevent the paper from being powdered off during the printing process. In addition, the absorption of xylene on coated paper is appropriate, and it can be used for fine mesh printing of 60 lines/cm or more.
The art paper we used for making rigid paper boxes is Lever-coated. We also call it C2S art paper. It has a smooth touch and white enough to print any color on it. The normal weight we use for wrapping paper is 157gsm or 128gsm, then laminated 2mm grey board to customize the paper gift boxes. And on the art paper, you can request any finish, such as lamination, foil stamping, full-color printing, embossing/debossing, or UV. The price of art paper is also much cheaper than many other fancy papers. See some rigid box samples made of art paper:
