Core Advantages

Precise Sterilization Indication
- Multi-mode Response: It supports the four current mainstream sterilization methods, namely steam, ethylene oxide (EO), formalin, and hydrogen peroxide sterilization. Its color-changing sensitivity is as high as 99.9%, and it can react quickly and accurately under various sterilization conditions, providing you with reliable sterilization indication.
- High-contrast Color Difference: The color difference before and after sterilization is ΔE≥5, which means the color difference is clearly distinguishable by the naked eye. This greatly avoids the risk of misjudgment caused by an unclear color change, making your judgment of the sterilization result more accurate.
- Immediate Feedback: The ink will change color immediately after the sterilization is completed, and the color change is irreversible. This allows you to know in a timely manner whether the sterilization is completed.
Environmental Protection and Safety
- Water-based Formula: Adopting a water-based formula, it achieves zero VOC emissions and complies with the REACH SVHC 236 and FDA 21 CFR standards. It is not only environmentally friendly but also creates a healthy working environment for operators.
- Non-toxic and Harmless: It does not contain harmful substances such as heavy metals and phthalates. It is suitable for direct contact with medical devices and pharmaceutical packaging, ensuring the safety of products and eliminating your concerns about the ink contaminating medical products.
- Migration Resistance: Even after sterilization, there is no risk of ink migration, ensuring the integrity of the packaging and the quality of the products.
Excellent Printing Performance
- Flexographic Printing Compatibility: It is suitable for anilox roller line counts of 200 - 300 LPI, and the printing speed can reach 150 - 300 meters per minute. It can meet the needs of different production scales and improve production efficiency.
- Strong Adhesion: It has strong adhesion on various substrates such as PET, PE, and paper, ensuring that the printed patterns are clear, durable, and not easy to peel off.
- Long-term Stability: In the non-sterilized state, the color remains stable for ≥12 months, providing convenience for your inventory management and reducing losses caused by ink deterioration.

Application Scenarios

Medical Device Packaging
- Sterilization Bag Labels: It can monitor the effectiveness of sterilization in real time and fully comply with FDA requirements, enabling you to have a thorough understanding of the sterilization status of medical devices.
- Surgical Instrument Tracing: By combining the color-changing mark with the batch number, the whole-process traceability of surgical instruments from production to use is achieved, facilitating management and quality control.
Pharmaceutical Industry
- Vial/Infusion Bag Labels: It is suitable for both moist heat sterilization (steam) and low-temperature sterilization (EO), providing a flexible sterilization indication solution for the pharmaceutical industry.
- Biosafety Labels: It is especially suitable for high-risk packaging of vaccines, biological agents, etc. It ensures that the sterilization effect can be accurately indicated under strict sterilization conditions, guaranteeing the safety of biological products.
Laboratory Consumables
- Petri Dish/Test Tube Labels: It can withstand hydrogen peroxide plasma sterilization, ensuring stable use in complex laboratory environments.
- Hazardous Waste Disposal Labels: The color change can promptly indicate the completion of sterilization, ensuring that hazardous waste is safely destroyed and avoiding environmental pollution.
