Notes for paper towels 
 Paper towel has become a kind of essential sanitary cleaning products in many people's lives, but the paper towel with full of beautiful things in eyes and all kinds of packaging often makes consumers dazzled. Experts remind that, to buy sanitary, clean tissue paper products, but also need to master four \"tricks\".
 
  Should choose the product of large enterprise, famous brand above all. The products of these enterprises have been inspected by the state for many times, and the quality is stable and reliable. At the same time, the production equipment of these enterprises is advanced, the production process management is strict, the quality of raw materials used is good. Although the price may be relatively expensive, but the use of sanitation, comfort, with ease.
 
  Second, look at the packaging. The name, address and telephone number of the manufacturer shall be indicated on the package of the product. Also pay attention to see whether the package is marked with the name of the product and the implementation of the standard, product grade, production date, period of validity, etc. It's best to buy the latest products.
 
  The third is the best choice with pure wood pulp production products. At present, the production of paper towel raw materials are complex, including cotton pulp, wood pulp, straw pulp, waste paper edge, waste paper and so on. Use waste paper edge, waste paper as raw materials for the production of products, quality is generally in the middle, low range, low strength, easy to drop wool, powder, some see water on the loose, summer used to wipe sweat, paper wool is easy to stick on the face.
 
  Four is the paper towel is not the whiter the better. In order to improve the whiteness of products, some manufacturers add excessive fluorescent brightener, resulting in the whiteness of tissue paper exceeding 90.0% of the specified A-level standard. Such products look unnatural and the tone is not soft.
 
Colored napkins
 At present in the domestic market began to appear a color napkin, can be roughly classified into three categories
One, monochrome or two-color LOGO

  Print the logo of your shop on the white napkin to play a certain role in publicity.
Second, dyeing napkin

  Napkin in the production process directly bleached into various colors, anyway, both sides are the same color.
 
Full color printing

  It is a paper napkin printed with various colors on a white paper towel. Colored napkins are sublimations of white napkins, allowing paper towels to be used into a colorful and colorful world. This kind of paper towel is more popular in foreign countries, used in festivals, birthdays, parties, family gatherings and other places, mainly to match and foil the scene, and then create a warm, romantic and enthusiastic atmosphere.
 
At home due to the financial storm influence in the international market, many color napkins export enterprises have the eye on the domestic market, domestic also appeared in tissue as a carrier of the emerging media, including a Beijing paper popular media development China's wedding theme color paper and advertising, the user's consistent high praise.
 
Requirements, processes and procedures for printing colored napkins
 As flexo printing belongs to ink printing, it is easy to cause swelling of paper when water or ink is large. After printing, local unflatness will affect the next printing and easily cause wrinkles. Meanwhile, the substrate material easy to swell will increase the fluctuation of tension and make the overprinter precision fluctuate greatly, which makes it difficult to produce good products. Secondly, due to the poor moisture resistance of toilet paper, after contact with the printing plate, it is easy to bring the loose fibers on the paper to the plate, resulting in paste plate, so that the printing can not be carried out continuously, and more seriously affect the printing quality and yield. Ordinary tissue paper is made of two or three layers of unwrinkled tissue paper, then by flexo printing, and then by toothed roll
 
  Paper roll embossed form a simple combination of Chinese napkins mostly belong to this kind. Today in most of Europe and the United States on the table napkin before printing to micro sizing material compound, the napkin is flat and level, no wrinkle, texture and massiness, more have a special product that is micro plastic composite products, its printing in the middle of the three layers structure, therefore has the very good texture and suppleness, product surface more beautiful.
 
  For napkins produced by domestic printers, efforts should be made to change embossing and pressing into the method of microsizing and compounding before printing, so as to make a qualitative leap in napkin quality. In addition, domestic napkins should also be improved in the material, in order to narrow the gap with foreign products. Such as as far as possible with high purity wood pulp production base paper, add enough anti - moisture agent, strive to meet the requirements of the surface smoothness and wet strength of printing.
 
Ink requirements
 Because napkin and people's life is closely related to, and involved in the service industry, so the requirements of ink safety non-toxic, strong adhesion, non - color.
 
  Napkins were initially printed with grease-based inks, characterized by good adaptability on the machine, but the prints had a particularly strong smell. Some napkin printers, using letterpress printing technology, have tried printing napkins with ethylene glycol ink (washable) to eliminate the smell of the print. But there are some problems with this process, such as ink blotting when the print meets ethylene glycol (liquid spreads out or permeates the paper); In addition, the ink on the machine is not ideal.
1. Main Advantages

  With the gradual progress of ink technology, napkin printing enterprises began to turn to more suitable flexible plate printing oil
 
  Ink, but also to feel the advantages of pigment inks over dye inks. In this context, flexographic printing technology has entered the stage of napkin printing. Its main advantages are as follows.
 
  (1) The odor is smaller, and has good chemical resistance and wear resistance.
 
  (2) Reduce ink and paper ink phenomenon. Some napkins dipped in the drink, the ink will rub dirty white table cloth or clothes, which will lead to consumer complaints. Flexo printing water-based inks consist of resins and waxes that harden when dried. Ink blotting is minimized when pigment is substituted for dye.
 
  (3) Environmental protection: Since waste inks (such as water-based inks and solvent inks) can recover pigments, water-based inks for flexo printing are more environmentally friendly. Because VOC does not produce flexo printing water - based inks to meet the reduction
 
  Environmental requirements for VOC emissions.
 
  (4) Improve the profit of the enterprise: reduce the price pressure and ink inventory, is very helpful to the enterprise's operation.
2. Notes

  If you are considering entering the napkins printing market, the most important thing is to understand ink and the relationship between ink and napkin printing. No matter what type of material is printed on the surface, it is important to understand that the color of napkin printing has its limitations. So in the selection of ink to pay special attention to the following points.
 
  (1) Knowledge of pigments. For example, know which pigments are not suitable for printing on napkins, for example
 
  Rose, methyl violet, alkaline blue, red C precipitate pigments, etc., because these pigments are associated with certain compounds (such as water and water)
 
  Ethanol, etc.) contact will affect the ink resistance.
 
  (2) There are two types of ink available for napkin printing enterprises, one is finished ink, the other is
 
  Concentrated ink. Finished inks can only be printed on a limited number of substrate, concentrated inks can be in more
 
  The substrate is printed, but some additives need to be added. Concentrated ink is very convenient to use, can be used in many
 
  This is important for printing machines and anilox rolls, as different machines are often used in batches.
 
  (3) In order to avoid the problem of poor resistance after the printing of napkins, it is necessary to understand the terminal application of napkins
 
  The process will be exposed to what substances, must be considered napkin printing ink to have a high alkali resistance, at the same time
 
  It also has to be resistant to substances such as milk, water and ethanol. The testing methods developed by the enterprise should be repeatable,
 
  To eliminate the influence of operator's subjective factors on the test results.
 
  (4) To consider the safety of napkin in the use of the skin and eyes, it is necessary to get familiar with some
 
  Terms such as casual food contact, indirect food contact and direct food contact, correct choice through direct food contact
 
  Certified ink. When the printer fully considered the above factors, will limit the napkin printing ink color choice
 
  In particular, many bright colors cannot be duplicated on napkins, and these limitations are increased
 
  The cost of ink.
