Drum cap seals are used for industrial container opening and are widely applied in filling lines on either steel drums or plastic drums. Chongyi is one of the top drum cap seal manufacturers in China. The 55-gallon drum cap seals, cooperating together with and differentiating from drum closure, are relatively lightweight and disposable, which makes them an ideal option as an anti-theft and directness-prevent cover. The metal drum cap seal has a full range of colors and customized logo designs which are frequently requested as an anti-counterfeiting selection.
