The N-200L L-type liner bag uses a dual-layer composite PE material that is tough and tear-resistant, suited to bulk storage in 200L large stainless steel drums. Produced entirely in a cleanroom, its particle and metal leaching levels meet semiconductor high-purity media standards, reliably protecting photoresists and cleaning chemicals. Supplied with a full sealing kit plus added butterfly clips for reinforced locking, it greatly improves sealing after large-volume filling, keeping out air and dust. The centred opening fits dedicated supply tubes for low discharge residue, and single-use operation removes the need to clean heavy drums — suited to large-scale raw material warehousing and transfer at wafer fabs.
