This blue ton bag developed by COSEK is specifically designed for sensitive materials such as electronic components and lithium battery materials that are prone to static electricity. Adopting anti-static polyester fiber woven fabric (surface resistance of 10 ⁶ -10 ⁹ Ω) and built-in transparent PVC breathable window (diameter of 30cm), it not only meets the requirements of electrostatic protection, but also can visually monitor the status of internal goods. The handle is designed with blue and white contrasting colors to enhance recognition, making it a safe choice for warehousing and transportation in industries such as semiconductors and new energy.
