1. Some toilet paper is thicker to the touch, and the grade of this paper is lower. Because, in the case of the same weight, the number of thick paper is small. For example, D grade paper has more than 270 sheets per 500 grams, while E grade paper has only 250 sheets or less. Therefore, in the case of the same weight, you should choose the whole package of thinner toilet paper.
2. Since toilet paper is sold by weight, individual manufacturers will add more fillers during the production process. The paper produced in this way is thick and hard, which is harmful to the human body. Therefore, you should choose soft toilet paper when buying.
3. The whole process of toilet paper production is completed under high temperature. If the packaging is not timely, incomplete or improperly stored, the paper will be damp and contaminated. Therefore, when selecting, you must choose products that are well packaged and have a relatively recent production date.
4. Pay attention to the industry standard of wrinkled toilet paper (QB2500-2000) issued by the Ministry of Light Industry. The standard divides wrinkled toilet paper into small roll paper and knife cut paper. The technical indicators are divided into A, B, C, D, Five levels of E. Knife-cutting paper for toilet use basically belongs to the two grades of D and E. When purchasing, please pay attention to the words on the package. If the implementation standard is indicated above: GB2500-2000 D-1, it means it belongs to grade D. Paper, good quality.
