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.
