In our daily life, toilet paper is an indispensable daily commodity, whether it is to wipe the mouth, wipe the hands, go to the toilet or clean, it is inseparable. Since toilet paper is a big consumable item at home, we tend to only focus on "large quantity" and "cheap" when buying. But you know what? These toilet paper are in direct contact with us, and its quality problems cannot be ignored, and if you buy that kind of inferior "toxic paper towels", it will also cause serious harm to human health. When buying paper towels, we often see that the tissue packaging says "first-class", "excellent" and "qualified", so what is the difference between the three different qualities of toilet paper, and how should we buy it? Let's talk about this problem with you today, let's take a look!
All walks of life will have a national standard, referred to as the national standard, its purpose is to ensure the quality of products and safeguard the rights and interests of our consumers. And toilet paper is the same, it also has a national standard. For example, the national standard for facial tissues, napkins, handkerchiefs, etc., which we usually use, is GB/T 20808, and the toilet paper used in the toilet is GB/T 20810. When buying toilet paper, we pay attention to check this national standard, as long as the paper towels that meet the national standard can be used. However, in the case of meeting the national standard, according to the quality and performance of the paper towel, it is divided into excellent products, first-class products and qualified products, so what is the difference between them?
One: the raw materials are different.
The raw material requirements of high-quality paper towels are relatively high, and 100% virgin wood pulp is usually used as its main raw material. Virgin wood pulp refers to wood pulp that is extracted directly from trees and treated by a special process, which is of high quality, soft in color and luster and requires high craftsmanship. Although the raw materials of first-class paper towels are also relatively high-quality, they are not completely limited to 100% virgin wood pulp. Grade 1 paper towels may contain a percentage of virgin wood pulp, but may also contain other non-wood pulp or secondary recycled materials. The selection of raw materials for qualified paper towels is relatively broad, using a variety of raw materials including wood pulp, straw pulp, bamboo pulp, etc., and may even contain a higher proportion of recycled materials.
Second: the physical properties are different.
The tensile strength of high-quality paper towels is high, and it is not easy to break even when it is pulled by a large external force, which can maintain the integrity of the paper. In addition, the softness of the high-quality paper towel is extremely high, and it can give a delicate and comfortable feeling when it comes into contact with the skin. In addition, the water absorption of high-quality paper towels is also very good, which can absorb liquid quickly and keep the paper shape not easy to break. It is especially suitable for people with sensitive skin, such as babies and the elderly, to minimize skin irritation. The first-class paper towels, whether in terms of tensile strength, softness and water absorption, are worse than those of the first-class products, and are suitable for ordinary families and personal use. If it is a qualified product, it is more likely to break, it will feel slightly rough to the touch, and its water absorption is relatively weak, this kind of paper towel is suitable for occasions with low quality requirements, and it can still be used reluctantly.
Three: the microbial indicators are different.
The microbial indicators of these three different grades of paper towels are also different, and the high-quality paper towel has the strictest control of microbial indicators, with the total number of bacterial colonies not exceeding 50 and the total number of fungal colonies not exceeding 20; The control range of first-class paper towels is slightly wider than that of first-class products, with the total number of bacterial colonies not exceeding 100 and the total number of fungal colonies not exceeding 80; The biological indicators of qualified paper towels are relatively looser, with the total number of bacterial colonies not exceeding 200 and the total number of fungal colonies not exceeding 100.
In general, it is an excellent product> a first-class product > a qualified product. So, we have it in mind when we buy toilet paper. Of course, as long as the toilet paper meets the national standards, it can be used, but the use experience and durability are different. In addition, the paper towels we buy at home are best not to be used indiscriminately or mixed. For example, facial tissues and toilet paper that we commonly use, facial tissues are usually used to wipe our mouths, and its hygiene requirements are very high. The toilet paper used in the toilet has relatively low hygiene requirements. In other words, toilet paper is far less clean than facial tissue, they cannot replace each other, and should be selected according to the actual use.
