paper drawing is a skill of choosing paper drawing:
1, look at the outer packaging:
1 the qualified paper drawing produced by regular manufacturers will be marked on the outer packaging with its executive standard number, production date, product quality, etc Shelf life and main raw materials. Specifically, the standard number is GT / t2008 and the shelf life is three years. In addition, the effective information such as product number, address and telephone number of the manufacturer will be indicated on the outer package.
secondly, there are many grades of paper drawing, among which the top grade is the best, followed by the first grade, followed by the qualified ones. When consumers buy, they can directly measure the quality of paper according to this standard.
unqualified paper drawing, the implementation of standards, production date is usually fuzzy, some even not.
2, pay attention to the production of raw materials
the raw materials of tissue production are more complex, including plant fiber, cotton pulp, wood pulp, waste newspaper and waste paper edge. At present, the paper produced from raw wood pulp in the market is better. It is from wood to pulp and directly to paper. The paper has high purity and does not mix with other materials.
in addition, there are two kinds of wood pulp: primary pulp and pure wood pulp. The primary wood pulp is simply a pure pulp made directly from plants without being used. Its main materials are reed, bagasse and plant fiber. The paper has good flexibility and fine fiber secretion; Pure wood pulp may also include recycled pulp, i.e. waste paper pulp, which may be made from recycled waste paper, so black spots and coarse holes will appear.
good tissue paper contains high amount of wood pulp, feel delicate and soft, not easy to drop powder and hair. And bad paper towel, its paper is hard, loose, easy to drop powder, hair, wipe on the skin and even pain.
in addition, if consumers feel a strong sense of particle in the paper towel, it means that the paper contains bleached lime water. It is recommended not to buy it, so as not to affect their health.
4 The tissue paper with better toughness than
is made of pure wood pulp or high content of wood pulp, so it has longer fiber, strong toughness, large expansion force and elasticity, and is not easy to be torn. The reporter did an experiment at the scene, holding a Vader’s log pulp paper in his hand, pulling hard, only to see that the paper has been pulled folds, but not broken. And bad paper due to the low purity of wood pulp, fiber short and fine, it is easy to brittle, a little force will appear fracture phenomenon.
5, observe the burning situation
, consumers can also use fire tissue to test the quality of paper. Usually, the paper with excessive fluorescent agent is white or black after burning, while the normal and qualified paper towel is natural gray after burning.
in addition, the paper towel can be soaked in water to see its quality. Good tissue paper has high density and toughness. Even if it is soaked in water, it will not be deformed and loose. And the paper towel with poor quality is soaked in water and easy to loose.
6, see whiteness
paper towel is not the whiter the better. In order to improve the whiteness of paper, some manufacturers will add excessive fluorescent whitening agent to remove stubborn dirt, so that the paper towel has a bright white and clean feeling from the external packaging. But the fact is just the opposite. The state has a clear regulation on the whiteness of tissue. The whiteness of tissue standard a and other products is 85.0% – 90.0%. If the whiteness of the paper exceeds 90.0%, it does not meet the requirements of the standard. The use of substandard tissue paper, light will appear skin itching, serious can lead to skin diseases, and even cancer. Therefore, it is suggested that consumers should not buy too white, or pan blue, pan blue paper.
the color of normal tissue should be ivory white and natural white. Consumers can test the tissue paper with a banknote detector. The paper with blue and purple light is usually added with excessive fluorescent agent.
2、 The paper quality identification method is
1 and the raw material is
. At present, most paper towels in the market will choose wood pulp, but wood pulp is also divided into original wood pulp and ordinary wood pulp, although it is also wood pulp, However, the paper produced is quite different. In order to reduce the cost, many enterprises will use ordinary wood pulp. However, in order to make publicity, under the banner of 100% wood pulp, I believe many consumers think this kind of paper is very good. However, they can find that Qingfeng brand paper towel has 100% native wood pulp written on the package, which is simply made from plants, The main materials of unused pure pulp are reed, bagasse and plant fiber. The paper has good flexibility and fine fiber secretion; Ordinary wood pulp may also include recycled pulp, i.e. waste paper pulp, which may be made from recycled waste paper, so there will be black spots and coarse holes. That’s the difference.
the continuous extraction of paper, because of the continuous exposure of quality, health and other aspects, so that many consumers worry, to identify the quality of the extraction of paper, in fact, you can use the cash detector to identify the pros and cons, to see whether the product contains fluorescent whitening agent, you can use the ultraviolet lamp (cash detector) in the dark, the bright contains fluorescent whitening agent. You can also carefully observe the surface of the paper, if the surface color is uneven, mixed with yellow, gray, usually with bamboo, bagasse and other wet pulp added to part of the white edge of the paper production, containing fluorescent whitening agent; If the color of the whole paper is gray white, and there are some black spots, it is recycled with office waste paper, containing more fluorescent whitening agent. As the role of fluorescent whitening agent is to enhance the blue light reflection, the surface of paper containing more fluorescent whitening agent will be slightly bluish.
and other aspects, such as softness and toughness, are also the key to quality inspection. You must choose the paper drawn from a regular manufacturer like Qingfeng, so that you can feel at ease.
generally, the number of qualified drawing paper will be marked in the outer packaging, that is, the number of sheets, the number of drawing, etc. many enterprises do not mark the quantity in order to confuse this problem. Some even mark it, but also confuse the words. For example, the 100 sheets and 100 sheets marked on box or soft tissue paper may indicate different meanings, and each drawing is usually 2 layers, 100 is 200. So for everyone’s benefit, or don’t covet cheap, choose big brand drawing paper is the best.
