Ester-soluble laminating composite printing ink

Abstract

The invention relates to an ester-soluble laminating composite printing ink comprising the components of, by weight: 15-35% of chlorinated EVA resin, 1-5% of MP resin, 18-38% of rutile-type titanium dioxide, 0.05-0.7% of fumed silica, 0.5-5% of phosphate, 8-15% of aldehyde and ketone resin, 15-25% of ethyl acetate, 3-8% of cyclohexane, and 2-8% of butyl acetate. The total amount of the components of the composite printing ink is 100%. The composite printing ink provided by the invention does not contain benzene or ketone, and has low solvent residue. Therefore, the composite printing ink satisfies a national food sanitation requirement. The composite printing ink has excellent printing adaptability, and can be adapted to printings of different speeds and different laminating machines. The composite printing ink has good rotary performance, and can be used for perfectly reproduce various printing level depths. The composite printing ink has a good composite performance, and can provide high composite strength in printing OPP composite film, woven bags, and non-woven fabrics.

Description

technical field [0001] The invention relates to a composite ink, in particular, the invention relates to an ester-melted film composite ink. Background technique [0002] In modern economic life, commodity packaging has become an important part of commodities. Compared with traditional packaging materials, plastic packaging has the advantages of lightness, transparency, stable chemical properties, moisture resistance, oxidation resistance, and strong air tightness. Therefore, plastic film Flexible packaging printing, which is mainly based on packaging and printing, occupies an increasingly important position in packaging printing. It is estimated that since 1980, in some advanced countries in the world, plastic packaging has accounted for 32% to 44% of the entire printed packaging. [0003] Generally speaking, because the protection of the contents of a single plastic packaging material is poor, it is difficult to meet the packaging requirements of heat resistance, moisture...
