Method for manufacturing base paper for tipping paper suitable for environmental-friendly ink satellite flexo printing technology

Abstract

A method for manufacturing base paper for tipping paper suitable for environmental-friendly ink satellite flexographic printing technology; comprising the following steps: a, beating process: using two kinds of pulp, bleached long-fiber coniferous wood pulp and bleached short-fiber eucalyptus wood pulp; For beating, the beating concentration of bleached long-fiber softwood pulp is 4.5%, the beating degree is 60°SR~66°SR, and the wet weight is 5g~6g; the beating concentration of bleached short-fiber eucalyptus pulp is 4.5%, and the beating degree is 64°SR~ 70°SR, bleached long-fiber coniferous wood pulp and bleached short-fiber eucalyptus pulp, according to the mass ratio of 45% to 50%: 50% to 55% pulping, the pulping degree of the net pulp is 66°SR to 68°SR , Wet weight 4.5g~5.0g; b. Addition process of auxiliary materials: Add 200kg / ton of paper light calcium carbonate, 100kg / ton of paper 325 mesh talcum powder auxiliary materials and 50kg / ton of paper pharmaceutical grade into the prepared mixed pulp Titanium dioxide.

Description

Technical field [0001] The present invention relates to the technical field of tobacco paper sheet, particularly a green ink flexo printing technique is applied tipping base paper manufacturing method. Background technique [0002] Flexographic printing using flexographic plates, the anilox roll aqueous green ink layer applied to a predetermined thickness uniformly in the graphic portion of the printing plate projection, then under the action of the impression cylinder, the graphic portion of the green water-based ink transferred to the surface of the substrate, to form a clear graphic. Divided stacked flexographic printing press, satellite, and three units of formula according to various arrangements. [0003] According to the American Flexographic Technical Association (FTA) to predict the future with the flexible packaging industry needs a substantial increase in flexo print, flexo proportion of share in the packaging sector will grow further. At present, my country's packagin...

Problems solved by technology

[0004] The packaging industry is mostly based on unit-type flexo printing machines, but with the market's requirements for production speed, customers' requirements for printing accuracy, and the country's higher and higher requirements for environmental protection, unit-type flexo printing machines can no longer meet the requirements

The main problem is that the substrate between two adjacent colors is driven by the printing plate, and it is difficult to align the substrate when printing plastic and film with high elasticity and deformation; the tension between colors is not easy to control, once the tension changes If it is too large, the paper and film will break, and the fabric will produce weft arcs. In order to avoid aggravating these problems, the production speed has to be reduced, and the printing efficiency will decrease accordingly.

[0007] Flexographic ink is the only non-toxic ink approved by the American Food and Drug Association among all printing methods. It is mainly made of water-soluble resin, pigment, solvent and related additives through compound grinding. The viscosity is relatively low. If the number of lines is too low, the amount of ink supply is too large, and the edge of the printing plate is easy to accumulate ink, which will cause ghosting on the edge of the printed product; Base paper should have good ink acceptance and certain water penetration resistance
