GSR Metal Caps is a proprietor-led manufacturer of roll-on pilfer-proof aluminium closures, based in Anakaputhur, Chennai.
We make caps in 20, 22, 25 and 28 mm with your choice of EPE or latex wad — the liner that decides whether a bottle holds its seal through transport, storage and shelf life.
The work is exacting: a cap a fraction out of tolerance jams a filling line or leaks in the carton. So we hold sizing tight, match colour batch to batch, and ship on the date we promise.
