Product FAQs
Which SD inner printing ink is suitable for food packaging?
Our SD-NP Light Packaging Inner Printing Ink is ideal for general food packaging applications. For high-temperature sterilization requirements (121°C), we recommend SD-NH High-performance Retort Inner Printing Ink which meets strict food safety standards.
Can SD inner printing ink be used for retort packaging?
Yes, our SD-NQ and SD-NH retort inner printing inks are specifically designed for high-temperature retort applications. SD-NQ can withstand 100°C water boiling, while SD-NH is suitable for 121°C high-temperature sterilization processes.
How does SD-NH ink perform in 121°C retort sterilization?
SD-NH High-performance Retort Ink is specifically formulated for 121°C autoclave sterilization. After sterilization at 121°C for 30 minutes, it maintains excellent adhesion (≥4.0N/15mm), no blocking, no migration, and stable color fastness. It meets medical-grade sterilization requirements and is ideal for prepared dishes and medical packaging.
What is the shallow dot reproduction capability of SD inner printing ink?
SD inner printing inks excel in shallow dot reproduction. Our SD-NP General Inner Printing Ink can reproduce independent dots as small as 2μm, ensuring clear and sharp small text and fine patterns. This is crucial for high-quality packaging printing with intricate designs.
What is the lamination strength requirement for food packaging inks?
For food packaging applications, SD inner printing inks achieve lamination strength ≥3.5N/15mm for dry lamination and solventless lamination. Our premium SD-NH ink maintains ≥4.0N/15mm even after retort sterilization, ensuring packaging integrity throughout the supply chain.
Can SD-NA tape ink withstand hot melt coating?
Yes, SD-NA PP Tape Ink is specifically designed for tape applications. It can withstand hot melt coating at 150-180°C without blistering, discoloration, or adhesion loss. The ink also passes 50°C/30min water boiling test, ensuring durability in various conditions.
Which SD ink is suitable for frozen food packaging?
For frozen food packaging applications, we recommend SD-NQ Retort/Frozen Ink for -18°C standard freezing and SD-NH High-performance Ink for -30°C deep freezing. Both inks maintain excellent flexibility and adhesion after prolonged freezing, preventing ink cracking or peeling. SD-NH can withstand 121°C retort sterilization followed by -30°C storage without performance degradation.
What is the low-temperature resistance of SD water-based ink?
SD water-based inks exhibit excellent low-temperature resistance. Our standard SD-NQ ink maintains flexibility down to -18°C for 6 months without cracking. The premium SD-NH ink extends this capability to -30°C for 12 months, suitable for deep-frozen seafood and medical products requiring ultra-low temperature storage. All our frozen food grade inks pass rigorous freeze-thaw cycle tests.
