PET High Barrier Film is a high-performance polyester film developed for high barrier applications. It provides excellent gas, water vapor, and flavor barrier performance. This advanced film uses special formulations and precision manufacturing processes to combine excellent mechanical strength, thermal stability, and chemical resistance, providing comprehensive protection for food, medicine, and electronic products.
Our PET High Barrier Film uses multi-layer composite structures and/or special additive technologies to significantly improve the barrier performance against oxygen, carbon dioxide, water vapor, and flavor molecules. The oxygen barrier performance is 5-10 times higher than standard PET, while maintaining good transparency and processing performance, making it an ideal choice for strict packaging applications.
The thickness range of this series of products is from 12μm to 125μm, which can meet different barrier requirements and application scenarios. Our PET High Barrier Film has excellent dimensional stability and thermal sealing performance, suitable for various composite and conversion processes, and is a reliable choice for packaging solutions for food, medicine, personal care, and electronic products.
