The Reed & Smith group (which acquired New Taplow Mill in 1950) became one of the biggest papermakers in the UK. A Fourdrinier machine was installed in 1892 and continued to make paper at Higher Kings until about 1972. A new machine was built in 1956 to make blue sugar bags and other products, and has been modified over the years to make different grades of paper and card. St Regis acquired Higher Kings in the early 1980s and since then the mill has diversified into making a wide range of recycled coloured papers and boards. It is now owned by Asia File Corporation.
