James Cropper’s OPTIVEIL® Polyester Veils Pass Key Medical Testing, Unlocking New Opportunities in Healthcare

The materials underwent an in vitro cytotoxicity study in accordance with ISO 10993-5, the international standard for biological evaluation of medical devices. Conducted under ISO/IEC 17025:2017 laboratory conditions, the study assessed the potential for cytotoxic effects from direct contact with the polyester veil. The veil passed all testing criteria, demonstrating it does not cause any adverse cellular reactions. 

OPTIVEIL®’s skin-friendly, breathable and durable properties make them ideal for long-term wear in medical devices. The veil’s uniform thickness and flexibility aid the production of pressure-sensitive adhesives and adhesive patches, while its mechanical strength enables integration with embedded electronics, in devices such as biosensors, smart bandages and therapeutic patches. The material also demonstrates excellent breathability and chemical resistance enhancing both patient comfort and durability. 

With this new certification, James Cropper’s OPTIVEIL® polyester veils are ready to be incorporated into next-generation medical products, offering manufacturers a trusted and versatile material that meets the demands of both clinical environments and patient care.
