Ink Series for Printing on PET
PET has excellent physical and chemical resistance, making it suitable for a variety of products, including bottles, membrane switch covers, IMD panels, and self-adhesive labels. We have developed a series of high-performance inks specifically for printing on PET, including solvent-based and UV-based inks, each suitable for printing on PET products with different applications.
PET is a non-polar polymer with high chemical stability and low surface tension, making it difficult to be soaked by most inks and solvents. However, due to its low surface tension, PET does not meet the surface tension required for printing. To increase the surface tension and improve the bond strength between the film and the ink, surface treatment is necessary before printing.
PET ink is screen-printed onto PET substrates to achieve a high-volume effect.

4. Viscosity: 15,000-20,000 oz.
5. Test Performance: 50 cycles with 500g force in 99% ethanol; 50 cycles with 500g force.
II. PET Ink Precautions:
A. Clean the substrate surface thoroughly. Stir thoroughly before use and add approximately 10% thinner.
B. When printing multiple colors, wait 20 minutes for the previous color to dry before printing the next color. Heat drying for 5-10 minutes after printing is best.
C. Do not mix with other inks to avoid reducing print quality. Add 5%-10% DB-01 curing agent if necessary.
D. Quality may be affected by factors such as materials, processes, molding conditions, and environmental conditions. Therefore, test the ink before mass production. Only print when it meets quality requirements.
E. After use, seal the PET ink securely and store it away from sources of fire, moisture, and light in a well-ventilated, moisture-proof, and dark place. Shelf life is one year.
