What are the packaging carton materials?

1. Single powder paper

Single powder paper is also called single-sided coated paper (single-sided coated paper).

1. The paper is smooth on one side and matte on the other side, only the glossy side can be printed;

2. Double copper paper

Double-coated paper refers to double-sided coated paper. Double-sided coated paper is a kind of coated paper, which is coated on both sides, and has good smoothness on both sides. This kind of material is relatively high-end in application, and Junye packaging and printing is currently doing well.

1. The paper is smooth on both sides and can be used for double-sided printing, while the single-coated paper has only one smooth side. However, the stiffness and hardness of single copper are higher than that of double copper. And the single copper is a little yellowish, and the luster is not as obvious as the double copper;

2. The biggest difference from single copper paper is the possibility of double-sided printing;

3. Commonly used surface treatment processes after printing: glue, UV, hot stamping, embossing, etc.
