Method for preparing environment-friendly tipping paper for cigarettes

Abstract

The invention relates to printing technologies, in particular to a method for preparing environment-friendly tipping paper for cigarettes, and the method belongs to water-based ink printing. The manufacturing method is characterized in that the depth of a tank of a plate cylinder ranges from 43 [mu]m to 60 [mu]m or ranges from 15 [mu]m to 37 [mu]m; the solid content of water-based ink is controlled to range from 36% to 55%, the pH value is controlled to range from nine to ten or the scattering fineness of paint is smaller than or equal to 15 [mu]m, and the viscosity is controlled to range from 18 s to 50 s; after the raw tipping paper for cigarettes is printed and coated, the back of the raw tipping paper for cigarettes is pre-dried through a preheating device in a guide roller before the tipping paper enters a drying oven for drying. According to the method for preparing the environment-friendly tipping paper for cigarettes, water-based ink intaglio printing can be adopted. Compared with the prior art, the method has the advantages that the production safety is good, printed patterns are clear and uniform, the content of heavy metal such as arsenic and lead is lower, ink is convenient to prepare, and cost is reasonable.

Description

technical field [0001] The invention relates to printing technology, in particular to a method for preparing cigarette tipping paper belonging to water-based ink printing. Background technique [0002] Cigarette tipping paper is a special paper (commonly known as tipping paper) that connects cigarettes and filters. When a smoker smokes, the cigarette tipping paper will directly contact the lips. Therefore, the State Tobacco Monopoly Administration has formulated Mandatory sanitary indicators and standards for paper loading to regulate the tobacco industry. As people continue to raise the voice of smoking and health, consumers have higher and higher requirements for the health index safety of tipping paper for cigarettes. At present, the tipping papers for cigarettes used by all tobacco companies at home and abroad are printed with organic solvent-based inks. After printing, a small amount of solvent remains in the tipping papers for cigarettes, which makes the hygienic indi...

Problems solved by technology

Since the base paper for cigarette tipping paper is thin, has large pores, and absorbs quickly, if the existing water-based ink gravure printing technology is used, the printed cigarette tipping paper is prone to paper shrinkage and deformation, poor storage stability, and printed surface. White spots, insufficient hiding power, flocculation of pigment particles and other problems, resulting in waste of cigarette tipping paper

It is extremely difficult to adjust various performance indicators to adapt to water-based inks printed with a plate cylinder groove depth of 38~42um
