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 PET printing inks specifically designed for eco-friendly printing applications, including solvent-based and UV-based inks, each suitable for screen printing on PET products with different applications.
As a non-polar polymer with high chemical stability and low surface tension, PET can be challenging to print on using traditional inks. However, due to its low surface tension, PET does not naturally meet the requirements for effective printing. To enhance the surface tension and improve the bond strength between the film and the ink, surface treatment is necessary before printing.
Our PET ink is designed for screen printing onto PET substrates to achieve a high-volume effect.
1. Applicable Materials: Various treated PET sheets and PET injection-molded parts.
2. PET Ink Characteristics: Slow drying, matte finish, good hiding power, vibrant colors, and stamping resistance, making it ideal for eco-friendly printing.
3. Surface Dry Time: 15-25 minutes; Strict Test Time: 24 hours after air drying; Baking: 60-75°C for one hour.
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 the PET printing ink thoroughly before use and add approximately 10% thinner.
B. When printing multiple colors, wait 20 minutes for the previous color to dry before applying the next color. Heat drying for 5-10 minutes after printing is recommended for optimal results.
C. Do not mix with other inks to avoid reducing print quality. If necessary, add 5%-10% DB-01 curing agent.
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. The shelf life is one year.
