We proudly introduce high-performance PE heat shrink tubing specifically designed for battery packaging. This innovative product is designed to provide a safe, reliable, efficient, and aesthetically pleasing outer protective solution for various battery types, including 18650, 21700, prismatic, and pouch cells. Made from premium PE material, this heat shrink tubing boasts excellent physical and insulating properties, making it an ideal choice for enhancing the quality and safety of your battery products.

This PE heat shrink tubing boasts a 2:1 shrinkage ratio. Upon heating, it wraps tightly and smoothly around the battery, forming a smooth, durable protective layer. It provides excellent electrical insulation, effectively preventing short circuits and leakage. It also boasts exceptional wear resistance, impact resistance, and flame retardancy (compliant with UL certification), protecting batteries from external damage and environmental risks during transportation and use, providing a solid safety barrier. Its wide operating temperature range ensures stable performance in diverse environments.

Extreme ease of use is the core advantage of this heat shrink tubing. Using a standard heat source (heat gun/oven), you can achieve fast, uniform, and flawless shrinkage. The smooth, flat package appearance is not only aesthetically pleasing but also significantly simplifies production processes, improving efficiency and making it a perfect fit for automated production lines, helping you reduce costs and increase efficiency.

We offer a wide variety of heat shrink tubing options, including a variety of colors (clear, black, and custom colors)and diameters to meet your specific packaging needs. Every batch of PE heat shrink tubing undergoes rigorous quality inspection to ensure dimensional accuracy and reliable performance. Choosing our battery-specific heat shrink tubing means you're choosing greater safety, enhanced protection, improved reliability, and more efficient productivity.
