PUNW type temperature resistant gravure ink is a new type of gravure ink designed for personal care products such as paper towels, toilet paper, and handkerchief paper. This product is free of benzene and ketone solvents. It is an upgraded product of NW inks. It has good printing adaptability on various films, and has excellent aging resistance and ductility. It is suitable for gravure or flexographic printing. The machine prints substrates such as PP, PE, and paper without composite requirements.
First, the performance characteristics
1. This product does not contain benzene and ketone solvents. The heavy metals used in the pigments do not exceed the standard, and the printed matter has no odor;
2. High temperature resistance, heat-sealing at 160 ° C / 1 sec / 0.3 kPA does not decolorize, does not migrate;
3. The surface is smooth, and the friction coefficient of the surface of the printed ink layer is small;
4. The printed matter is fast drying, non-returning, non-migrating, non-curling, and has good ductility;
5. Excellent printability for low speed to high speed printing.
Second, the applicable substrate
PE: handled above 38 dynes
CPP: processed above 38 dynes
Coated paper, decorative paper
Third, use and scope
It is mainly used for the packaging of personal care products such as soft facial tissue, toilet paper, and handkerchief paper, as well as the printing of decorative paper.
brush.
Fourth, printing viscosity
White ink: 11~14 seconds/25°C No. 3 Chaen Cup Color ink: 13~16 seconds/25°C No. 3 Chaen Cup
Five, thinner
No. 1: n-propyl acetate 20% ethyl acetate 60% isopropanol 20%
No. 2: n-propyl acetate 40% ethyl acetate 30% isopropanol 20% butyl ester 10%
No. 3: n-propyl acetate 60% isopropanol 20% butyl ester 20%
Note: The fastest dry No. 1 ~ the slowest dry No. 3 (standard solvent is No. 2)
Six, matters needing attention
1. Please do not mix with other alcohol-soluble inks from other manufacturers. This product is not suitable for composite packaging printing;
2, due to the different plastic substrates used in each factory, the adhesion of the ink will be different, so the ink adhesion of the plastic substrate used should be evaluated before printing to avoid loss;
3. The content of isopropanol in the diluent should not exceed 10%;
4. Some CPP and PE plastic films can obtain good adhesion and slip after 2 to 4 hours of printing. When overlaying with other factory inks, first evaluate the adhesion of the laminate and the coefficient of surface friction;
5. If you want to use it for surface printing, you need to evaluate the gloss and adhesion before using it.
6. When using a small amount of red or yellow and a large amount of white ink to adjust the spot color, the spot color fastness level will be adjusted.
Drop to level 1-2, if there is a need to adjust this light-resistant spot color, please consult the technical department of the company, the customer does not
Be self-adjusted to avoid loss;
7, the product should be kept away from fire, sealed and stored for one year.
