Definition and difference between single coated paper and powder gray paper

1. Definition: Single powder is coated paper in China, and double powder is double copper. Single powder has a smooth surface and is used for printing. The paper has good quality and whiteness. Art paper, that is, pink cards, are generally thicker. More than 250 grams, used for mounting paper. Mounting pits are mainly used for large-scale external packaging and are not suitable for printing books, except blackboard books. One side of the paper is slightly white, and the bottom is gray.

2, the difference:

(1) Different colors: the whiteness of single powder is higher than that of powder gray paper, so we can compare them before buying in the market and choose the paper with appropriate whiteness.

(2) Different scope of application: most of art paper is used for mounting paper and pits, mainly for large-scale external packaging, and some single powder will be used for printing books. These two kinds of paper have different application scopes.

Extended data:

The double-sided coated paper in the packaging box material is a kind of coated paper, that is, double-sided coating, and both sides have good smoothness. This kind of information is advanced in application. At present, Ye Jun has done a good job in packaging and printing.

This paper is lubricated on both sides and can be printed on both sides, while coated paper is lubricated on one side only. But the rigidity and hardness of single copper are higher than that of double copper. Moreover, single copper is a little yellow, and its luster is not as obvious as that of double copper.

In addition, the biggest difference between this paper and single copper paper is that it may be printed on both sides, while pit paper is a smooth kraft paper and corrugated paper (collectively referred to as paper core), which is one of the important materials for paper packaging.
