Self-adhesive label Is also called self-adhesive label material. It is a composite material made of paper film or other special materials, coated with adhesive on the back, and coated with silicon protective paper as the base paper.And after printing die - cutting and other processing into finished labels. Self-adhesive materials are usually printed and processed on the label linkage machine. The most common printing form is letterpress, and other printing methods are also used.Common faults in the printing stage are: Fault The ink layer on the printed label surface does not dry, dries slowly or the ink layer is wiped off. Cause The printing ink layer is too thick, the amount of ink is too large and the additives used in the ink are not suitable for ink denaturation or the type of ink used is not suitable, which will cause the label ink layer after printing to dry slowly or wipe off the ink layer; In addition, the machine was running too fast and dry Solution Using deep ink thin printing method to reduce the thickness of the ink layer Use fast drying special ink Add the desiccant with the supporting additive Take measures to extend the drying or curing time of printed matter Raise room temperature, appropriate exhaust, speed up ink drying Sinograce chemical produces various kinds of printing ink raw material resin, welcome to consult 

Water-based flexible printing ink is made of water-soluble pigment and water-based additives by a series of process grinding.Flexo water-based ink is suitable for printing various plastic woven bags, plastic handbags, non-woven bags, paper labels, kraft paper bags, corrugated paper, etc.It is non-toxic and odor free, it is not only environmental protection and safety but also can save 30% of the printing paper is a variety of water-based ink.

Plastic film as the object of packaging printing, many kinds, and the use of printing also involves many aspects, so the variety of this kind of ink is extremely wide.In particular, this ink shall have the characteristics of fastness to adhesion printing effect processing tolerance and other requirements.The surface of plastic film is smooth, and the ink can not be permeated, so it must be printed with strong adhesive ink of the film. Therefore, it is very important to have a reasonable ratio of various resins and solvents with strong adhesive of plastic film.Therefore, it is very important to make a reasonable ratio of different resins with strong adhesion to plastic films and solvents for dissolving resins.In the case of insufficient ink adhesion, often like polyolefin film through surface treatment to adjust the surface tension of the film, in order to improve its adhesion to the ink.Printing packaging supplies, generally should have bright color printing effect.In addition, after processing should have layer and bag making suitability and other processing suitability; According to the various uses of printing processing products, ink film is required to have friction resistance, rubbing resistance, cold resistance, water resistance, boiling resistance, content resistance and other endurance; In addition, when printing food packaging materials, special requirements for low odor and safety. Plastic film packaging gravure printing ink can be roughly divided into two kinds: external printing (table printing) with ink and printing (printing) with ink.Table printing ink requires gloss adhesion strong rubbing; Printing ink requires a suitable pressure film.Table printing ink for snacks, bread and other food packaging materials and fertilizers, feed, clothing, groceries and other packaging materials printing; The printing ink is used for printing packaging materials such as fast food, pickles, boiled food, distilled food and washing products.

Water-based ink is composed of resin (water-soluble resin colloidal dispersion emulsion polymer) aqueous amine (mainly ammonia) pigment (organic pigment inorganic pigment) and additives.The so-called water-based ink is mainly water as a solvent by scientific processing, compared with other printing ink, water-based ink, because it does not contain volatile toxic organic solvents, so in the printing process on the health of the printer operators without adverse effects, no pollution to the atmosphere, no pollution to the printing itself.Because ink painting has the characteristics of non-flammable, it can also eliminate the hidden danger of inflammable and explosive in the printing workshop, which is conducive to safe production.Water-based ink includes water-based screen printing ink water-based gravure ink water-based flexo (relief) ink. Sinograce Chemical is mainly engaged in the business of screen printing ink and other product series.Good materials, advanced production technology, and fine manufacturing techniques are used in the production of chemical liquids.
