UV Screen Ink For Plastic

Suitable For Demanding Packaging And Printing Applications

- Instant Curing, High-Efficiency Production: Utilizing a highly reactive photosensitive formula, curing is completed in 1-3 seconds under UV mercury lamp or UV LED light sources (395nm-410nm), eliminating the need for prolonged drying. This allows for immediate stacking, die-cutting, and subsequent processing after printing, significantly improving production efficiency and reducing production line waiting costs, meeting the high-speed mass production needs of the packaging industry.

- Environmentally Friendly and Safe, Worry-Free Compliance: Solvent-free (zero VOC), with low residual odor after curing, ensuring human safety and environmental friendliness. Some models have passed food contact safety certifications such as FDA 21 CFR 175.300, LFGB, and GB 31604.8, with migration levels ≤0.01mg/kg, fully complying with the stringent packaging safety standards of industries such as food and pharmaceuticals, eliminating safety hazards.

- High Adhesion and Durability: Exhibits excellent adhesion to various packaging substrates including gold and silver cardboard, coated paper, PP/PE plastics, tinplate, and PET, with no peeling observed in cross-hatch and 3M tape tests. The ink film boasts high strength and flexibility, resisting scratching, folding, and stamping. It can withstand low-temperature freeze-thaw cycles (-30℃ to 25℃) during cold chain transportation and 72 hours of oil immersion, ensuring long-lasting and stable printing results.

Key Usage Points:

1. Before printing, thoroughly stir the ink to ensure even pigment dispersion and prevent color differences or uneven printing; if concentration adjustment is needed, use a dedicated diluent, adding no more than 5%.

2. It is recommended to use 70-75 degree polyurethane squeegees. Select the appropriate mesh size based on the substrate characteristics. Control the squeegee pressure and speed during printing to ensure a uniform ink layer and clear lines.

3. Curing equipment should be checked regularly. It is recommended to replace UV lamps after 1000 hours of use to ensure stable curing results; after printing, confirm that the ink is completely cured before proceeding with subsequent processing to avoid problems such as peeling or tackiness.

4. For special substrates (such as some PET and PE materials), please conduct a small-scale compatibility test before mass production to confirm that adhesion and other properties meet the requirements before proceeding with full production.

Safety and Storage

1. Avoid skin contact with the ink during use. If accidental contact occurs, wash immediately with soap and water. It is recommended to wear gloves, masks, and other protective equipment during operation, and ensure good ventilation in the work area.

2. Store the ink away from light, direct sunlight, fire, and heat sources. Do not mix with strong oxidizing agents or other chemicals.

3. After opening, seal the ink tightly and use it as soon as possible to prevent performance changes due to exposure to air. If slight sedimentation occurs during storage, shake well before use.

Does the ink have an odor after curing?
The residual odor after curing is extremely low, meeting the strict requirements for packaging odor in the food, cosmetics, and pharmaceutical industries, and will not affect the quality of the product itself.

Can both ordinary UV lamps and UV LED lamps cure this ink?
Yes, the product is compatible with both UV mercury lamps and UV LED light sources (395-410nm). Customers can choose the appropriate curing method based on their existing equipment without needing to replace any equipment.

Can the printed product withstand low-temperature environments?
Yes, the ink film has excellent flexibility and shows no embrittlement or peeling after 10 freeze-thaw cycles (-18℃ to 25℃), making it suitable for cold chain logistics packaging.
