Complete Protection for Finished Battery Cells
Battery outer cell-wrapping film is a protective adhesive film designed for finished lithium battery cells. It uses PET polyester film as the base material and is applied around the entire battery cell before shipment.
The film provides four key protection functions for battery cells. First, it offers reliable electrical insulation. Second, it improves resistance to wear and surface damage. Third, it helps prevent oxidation and corrosion. Fourth, it provides a suitable surface for labeling and product identification.
These features make the film suitable for consumer batteries, power batteries, and energy storage battery applications. It helps battery manufacturers improve cell safety, appearance quality, and product consistency during storage and transportation.
Clean Workshop and Independent Production Zone
We operate our factory under strict clean production standards with effective control of dust and contamination. This controlled environment is suitable for manufacturing advanced materials used in lithium battery applications.
We also have a dedicated production area for new energy materials, operated by a professional manufacturing team. The equipment and production processes in this area are designed to meet the quality requirements of the power battery industry.
Our modern factory started operation in 2021 with an investment of RMB 150 million. The facility is equipped with an RTO waste gas treatment system that achieves 99.8% waste gas removal efficiency and recovers heat energy during operation.
These environmental protection measures help improve energy efficiency and reduce production impact. Our Battery outer cell-wrapping film is manufactured in a clean, controlled, and responsible production environment.
