Tynewydd tinplate works was founded in 1874 next to Pontnewydd railway station by Batchelor and Co (or Charles Roberts). It passed through a number of owners before becoming part of the Redbrook Tinplate Co. of Monmouth. In 1904 a subsidiary, the Pontnewydd Tin Stamping Co. opened a tin box factory immediately to the North of the tinplate works and sharing offices, later becoming part of Linpac. The tinplate works closed in c.1961 but the stamping factory seems to have carried on until c.1966. The site has been cleared and has been re-used for light industry.
