The 200L ultra-clean dual-layer PE drum is built for bulk high-purity material storage and transport. Its reinforced body withstands the forces of long-distance transfer and stacked storage. The dual-layer one-piece process structurally blocks impurity leaching risk. Produced and treated in a cleanroom with strict particle and metal ion leaching control, it preserves the purity of wet electronic chemical concentrates. Suited to large-batch plant raw material turnover and cross-region transport, with customisable drum colours — a preferred container for large-scale material storage in the semiconductor supply chain.
