Single powder

1. Commonly used paper box materials, the paper thickness varies from 80g to 400g, and the higher thickness requires two sheets to be mounted.


2. The paper is smooth on one side and dumb on the other. Only the smooth side can be printed.

4. The common surface treatment processes after printing are: over-gluing, over-uv, hot stamping and embossing.



Pit paper

2. Common ones include single pit, double pit and three pit.

3. It can print various colors, but the effect is not as good as single powder.
