How to choose the paper extraction
There is a wide variety of paper available in the market, but it is very mixed, so the price is the main measure for consumers to weigh the benefits of paper. It is really easy to choose hygienic and pass the paper extraction, teach you 6 tips to pick out a good paper towel.
Look at the outer packing
The standard drawing paper produced by regular manufacturers will be marked on the outer packaging with its executive scale number, production date, shelf life and main materials. To be specific, the execution scale is GT/T2008 under normal circumstances and the shelf life is three years. In addition, useful information such as the product number, address and telephone number of the manufacturer will be indicated on the outer package.
Secondly, there are many grade scales of paper extraction, among which the top grade is the best, followed by the first grade, the passing grade. Consumers can directly voucher when purchasing this scale to weigh the benefits of paper.
Failed drawing paper, execution scale, production date is usually indistinct contrast, some even do not.
Take care to produce raw materials
Paper towel production material is relatively large, there are plant fiber, cotton pulp, wood pulp, waste newspaper and waste paper edge. Now on the market is the production of wood pulp paper is better, it is from wood to pulp, directly to paper, paper purity is high, do not mix other materials.
In addition, wood pulp has primary pulp and pure wood pulp two kinds. Native wood pulp simply said is made directly from plants, not through the use of pure pulp, its main materials are reed, bagasse and plant fibers, paper flexibility is good, fiber excretion control is delicate; And pure wood pulp may also include recycled pulp that is, waste pulp, may be made of accepted waste paper as material, so it will be black spots and thick holes.
feel
Good paper towels contain high wood pulp, feel delicate and soft, not easy to drop powder, hair. And not good tissue, its paper is hard, loose control, easy to drop powder, hair, wipe on the skin and even have pain feeling.
In addition, if consumers feel a strong grainy feeling in the paper towel, it means that the paper contains bleached lime water. It is advised not to buy the paper to avoid health problems.
Specific toughness
Good tissue paper because the original material is pure wood pulp, or wood pulp content is high, so the fiber is long, strong toughness, large expansion tension, elastic, not easy to be torn off. The reporter did an experiment at the scene, holding a Weida wood pulp paper, pull hard, I saw the paper was pulled up the fold, but did not break. The paper is not good because of the low purity of wood pulp, short and fine fiber, it is easy to break brittle, a little force will be generally broken signs.
Investigation of combustion
Consumers can also test paper by burning paper towels. Usually, the paper with excessive fluorescent agent is white or dark after burning with fire, and the paper towel with normal grade is natural gray after burning.
In addition, you can also soak the paper towel in water to see its quality. Good tissue paper density, toughness, even if soaked in water, will not be loose deformation. Poor quality paper towels, on the other hand, can easily loosen when soaked in water.
whiteness
The whiter the tissue, the better. In order to improve the whiteness of paper, some manufacturers will add excessive fluorescent brightening agent to remove stubborn dirt, so that the paper towel from the outer packaging has a bright and clean new feeling. On the contrary, the whiteness of tissues is clearly defined by the government, and the whiteness of products such as tissue scale A ranges from 85.0% to 90.0%. If the whiteness of paper is over 90.0%, it does not conform to the scale requirements. Using improper tissue paper can lead to itchiness, skin diseases and even cancer. Therefore, consumers are advised not to buy too white, or green, blue paper.
Normal tissue color should be ivory white, natural white. Consumers can use the detector to do the test against the tissue paper, where the blue purple light paper, usually added with excessive fluorescence agent.
