Nowadays, there are many kinds of multifold tissue paper towels in this society, so how should we check the quality of multifold tissue paper towels?
1. Some multi-layered paper towels are thicker to the touch, and the grade of this paper is lower because there are fewer sheets of thick paper with the same weight. 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, a thicker multilayer paper towel should be selected.
2. Since multifold tissue paper towels are 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 a soft multifold tissue paper towel when buying.
3. The whole process of multifold tissue paper towel 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 those products that are well packaged and have a relatively recent production date.
4. Pay attention to the industry standard (GB2500-2000) of the Ministry of Light Industry on wrinkled multilayer paper towels. The standard divides wrinkled multilayer paper towels into small roll paper and knife cut paper. The technical indicators are divided into A, B, Five levels of C, D, 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 for toileting. Paper, good quality.
The quality of multifold tissue paper towels is directly related to the pulp
There are many kinds of raw materials for the production of multifold tissue paper towels, such as waste paper, wheat straw, reeds, sugarcane, wood, etc., and plants containing fibers can be used to make paper. However, due to the pollution caused by the papermaking process, the cost will vary depending on the material. Not the same.
According to the different pulps, household paper pulp can be classified into: wood pulp, straw pulp, sugarcane pulp, reed pulp, cotton pulp, and recycled waste paper pulp. The quality of paper towels produced by different pulps is different, and there are high, middle and low grades.
high-end paper towels are refined from 100% virgin wood pulp, which is of good quality and hygienic microbiological indicators. Physical indicators are better than other raw materials, pure wood pulp itself has a light egg yellow.
Mid-range paper towels are processed from straw pulp, sugarcane pulp, and cotton pulp. The quality is good, and the hygiene is inferior to the former.
low-grade paper towels are made from recycled waste paper beating. They often contain impurities, shed hair and swarf, and have no hygiene at all. The middle and low-end multifold tissue paper towels currently on the market are pulp made from recycled waste paper, with recycled paper printed matter and printed white paper edges, and even household waste paper.
