Surface Protection for Battery Production
Blue PET cell wrapping film is a protective adhesive film designed for lithium battery manufacturing applications. It uses blue PET or PP film as the base material and is coated with low-tack pressure-sensitive adhesive.
The film is widely used to protect battery shell surfaces and electrode sheets during production and transportation. It helps prevent scratches, dust, and contamination that may affect product appearance and quality.
The blue color provides excellent visibility on production lines, allowing operators to quickly identify the protective film and improve process management. With reliable protection performance and easy identification, this film provides a practical solution for battery manufacturers.


Precision Equipment and Clean Workshop
Our factory is equipped with high-precision rewinding and slitting machines to ensure accurate dimensions and good surface flatness. We operate under strict clean production standards and control dust and contamination throughout the manufacturing process.
This controlled environment helps maintain a clean film surface and stable product performance. We use an ERP management system to monitor the complete production process, including material purchasing, production scheduling, quality inspection, and finished product storage.
This digital management system improves production efficiency and helps maintain consistent quality and reliable delivery schedules. We have established a complete quality management system and are certified to ISO9001:2015 and IATF16949:2016 standards.
Our Blue PET cell wrapping film is manufactured through this controlled production system to ensure stable performance and reliable quality.
