1. Toilet paper on the market is produced according to national standards (GB20810-2006 toilet paper (including toilet paper base paper)). Toilet paper products are dazzling, and the packaging also has its own characteristics. At present, there are extraction type, drum type, flat form, etc. According to the standard of GB20810-2006 toilet paper (including toilet paper base paper), the grade is divided into three grades: excellent product, first-class product and qualified product.

The whole process of toilet paper production is completed at high temperature. However, if the packaging is not timely or the storage is not good, it will make the paper damp or contaminated. Consumers should choose toilet paper with good packaging and close production date when purchasing, and pay attention to the shelf life.
3, single-layer paper thicker toilet paper grade is lower, in the same weight you should choose the whole package of thicker toilet paper.
Since toilet paper is sold by weight, individual "smart" producers will add more fillers in the production process. This kind of paper is thick and hard, which is harmful to human body. The more savvy you should choose the softer texture of toilet paper.
The toilet paper usually used is processed by high temperature deinking and bleaching. The paper is too black, indicating that the deinking treatment is not good, and the residual ink is harmful to health. But too much bleach is equally harmful to the human body. High-grade toilet paper uses ink-free waste paper as raw material, without deinking and bleaching, and is naturally white (similar to milky white). So you should choose natural color toilet paper.
6, knife cut toilet paper according to the lines can be divided into cross cut and straight cut two kinds. The strength of the paper is lower in the direction perpendicular to the grain and higher in the direction parallel to the grain. Therefore, when you need to tear and cut, you should follow the direction of the vertical lines, and when using, you should try to follow the direction of the lines.
7. If it is used by the elderly or infants, you should try to choose higher-grade toilet paper, and do not cause unnecessary troubles for small cheapness.
8. Wrinkled toilet paper has good water absorption and oil absorption performance. If you use it to wipe the stove and range hood, you will receive unexpected results.
