This white cylindrical ton bag launched by COSEK, with the core advantage of "leak proof sealing+uniform bearing", is specially designed for liquid, paste or powder materials with strong fluidity (such as lotion, paint, chemical slurry). Using white PP woven fabric (including anti-static agent) and cylindrical barrel structure, paired with a red handle, the bag mouth is equipped with a screw cap and sealing gasket, which is an efficient packaging solution to prevent leakage and maintain material uniformity, especially suitable for industrial production processes that require precise measurement.
