High-Purity OCA Release Films for Precision Bonding in Medical, Food-Safe, and Optical Applications
Engineered for excellence across industries, our range of OCA (Optically Clear Adhesive) release films delivers unmatched performance in medical-grade, optical-grade, and conductive adhesive applications—alongside a specialized Food Contact Grade variant that meets stringent safety standards. These films are designed to support high-precision bonding processes while ensuring consistent quality, clean removal, and minimal residue. Whether you're developing advanced medical devices, precision optics, or food-safe packaging solutions, our release films provide the critical interface between adhesives and substrates—ensuring reliability from manufacturing to end-use.
Key Features: Ultra-thin profile (12–50 μm), low surface energy, excellent dimensional stability, thermal resistance up to 150°C, non-stick properties with controlled peel force, and compatibility with UV-curable and thermally activated adhesives. Each film is manufactured under ISO-certified conditions using premium raw materials, ensuring batch-to-batch consistency and compliance with global regulatory frameworks such as FDA, EU 10/2011, and RoHS.
Detailed Description:</strong> Our Medical Grade OCA Release Film is specifically formulated for use in implantable and diagnostic devices where biocompatibility and sterile processing are essential. It features a silicone-coated polyester base that allows for easy release without damaging sensitive surfaces like polymers or glass used in surgical tools or wearable sensors. The Optical Grade OCA Release Film supports ultra-low haze (<0.5%) and high light transmission (>98%), making it ideal for touchscreens, display laminations, and AR/VR components. For conductive applications—such as flexible printed circuits or EMI shielding—our Conductive Adhesive OCA Release Film ensures uniform pressure distribution during lamination, preventing air bubbles and enhancing electrical continuity. Meanwhile, the Food Contact Grade OCA Release Film is compliant with FDA 21 CFR 175.105 and EU Regulation (EC) No 1935/2004, offering safe separation from food packaging adhesives used in ready-to-eat meals, beverage containers, and shelf-stable products. All variants are available in roll formats (up to 1000 m) and customizable widths (from 50 mm to 600 mm), enabling seamless integration into automated bonding systems
Applications: Ideal for manufacturers in healthcare (surgical instruments, diagnostic equipment), electronics (smartphones, tablets, automotive displays), and food packaging (industrial labeling, sealed pouches). These release films also serve niche markets including aerospace composites, photovoltaic modules, and smart labels requiring tamper-evident adhesion. Their versatility extends to R&D labs exploring new adhesive technologies, where consistent film behavior under stress tests enhances reproducibility
User Feedback:"We switched to this Medical Grade OCA Release Film for our next-gen endoscope assembly line and saw a 40% reduction in adhesive residue issues. The peel strength consistency was remarkable." – Dr. Lena Müller, Biomedical Engineering Lead, Germany. "Our optical device team reported zero haze-related complaints after adopting the Optical Grade variant—it’s now our standard across all display projects." – Rajiv Patel, Product Manager, India. "The Food Contact Grade film passed our internal migration testing with flying colors; we now use it for all cold-fill packaging lines." – Sophie Moreau, Quality Assurance Director, France
"Optical Release Film for Medical Industry ensures biocompatible, low-haze demolding for diagnostic displays and endoscopic optics, while Conductive Adhesive OCA Release Film integrates electromagnetic shielding with precise adhesive control for wearable medical sensors and EMI-sensitive surgical device interfaces.
Frequently Asked Questions:</strong> How do these films differ from generic release liners? Unlike standard PE or paper-based liners, our films offer superior clarity, chemical resistance, and controlled release forces tailored to specific adhesive types. Are they recyclable? Yes—they are made from polyethylene terephthalate (PET) and can be processed through industrial recycling streams. Can they withstand autoclaving? Only the Medical Grade version is suitable for gamma sterilization and ethylene oxide exposure, not direct steam sterilization. Optical Release Film For Medical Industry Do they meet international standards? Absolutely—the Food Contact Grade complies with EU and US food contact regulations; the Medical Grade adheres to ISO 10993 biological evaluation guidelines. What about environmental impact? We minimize VOC emissions during production and offer low-waste packaging options for bulk orders.
