Visqueen is a brand of polyethylene plastic sheeting produced by British Polythene Industries Limited. It is the registered trade mark of British Polythene Limited in numerous countries throughout the world. In 1991 the Chairman John Sefton, agreed to establish an endowed fund based on the profitability of the Stockton branch of the company.
In November 2008 the owner of the plant, British Polythene Industries (BPI), announced that the site in Stockton had made losses over the previous two years, and continued to suffer due to the decline of the construction sector, to which it supplied 40 per cent of its products. Closure of the plant followed a year later.
The legacy of Visqueen and its presence as part of the industrial heritage of Stockton continues with the distribution of support from their fund.
