How do I distinguish between copy paper and tissue paper?

In the market, it is often the case that the tissue paper is sold as a copy paper, but the production standard of the two paper is different, and there is a certain difference in price, so how to distinguish the copy paper from the colored tissue paper sheet?

Method one: check its appearance is smooth, exquisite, have uniform transmittance.

Copying paper is a kind of advanced cultural industrial paper which is very difficult to produce, with fine paper, smooth surface and good transmittance. The process of sheet paper is relatively rough, paper is generally one side light and rough side.

Method 2: To check the physical strength and tear of the paper, the higher the transparency and the higher the quality of the paper.
The paper has good transparency, usually covering up to 6-8 layers, still seeing the presence of transparency, and the extremely good card is up to 12 layers. The tissue paper is thin and soft, and has a certain degree of transparency, but is far from the copy paper.
The paper is very similar to the sheet's appearance at a glance, but in fact, the quality of the sheet is poor and the price is less than that of the copy paper, so the customer must polish the eye to avoid unnecessary loss when purchasing the paper.
