The 200L equal-opening composite PAIL drum uses twin equal-diameter openings that connect flexibly to filling and conveying lines for recycling discharge on automated production lines. The outer steel drum provides strong mechanical protection, and the ultra-clean barrier liner effectively prevents container leachables from contaminating high-purity reagents. The entire production process follows strict clean control, steadily managing particle and ion leaching. The solid, impact-resistant body suits long-distance freight and is widely used for storing and transporting semiconductor wet electronic chemicals, with drum colours customisable on request.
