The second check of its physical strength performance shows that the tearing degree is high, indicating that the higher the transparency of the copy paper, the higher its quality.

Tissue paper and copy paper
The market often sells tissue paper as copy paper. Why does this happen? There are four main reasons:
1. Due to the impact of a large number of fake copy paper on the copy paper market, the price of copy paper has fallen sharply. If you produce real copy paper, the manufacturer will have to pay 3000-5000 yuan/ton, so many excellent domestic enterprises dare not produce Real copy paper.
Second, it is tissue paper, but in order to get a good price, use the name of copy paper to promote sales in order to obtain profit.
3. As some authoritative persons interpret the copy paper as thin typing paper, this misleads the manufacturer.
