This black ton bag launched by COSEK is designed for high-precision material transportation in industries such as electronics, semiconductors, and pharmaceuticals, with "anti-static+dust-free packaging" as its core function. Using conductive PP woven fabric (surface resistance 10 ⁶Ω -10 ¹⁰ Ω), paired with a wide black handle (width 8cm), and a transparent PE lining (anti-static film) inside the bag opening, it can effectively prevent electrostatic discharge (ESD) from damaging sensitive components, making it an ideal packaging carrier for products such as chips, circuit boards, and precision instruments.
