Restructuring operations and cost reduction plans have boosted British Polythene Industries (BPI), which has recorded a 200% increase in pre-tax profit to £11.2m ($16.7m) last year.
BPI said the company's capacity reduction of 30,000 tons from its Stockton facility helped it post a better financial report.
As a part of restructuring, BPI is investing £4.5m ($6.7m) in a new film production line for its Ardeer facility as a replacement for the Stockton unit, the company said.
The company is also in the process of closing its Cumbrian films facility in Brampton, which is set to take place next month.
BPI said its operating profit before restructuring costs increased to £19m ($28.3m) compared to £12.6m ($18.7m) in 2008 and its turnover declined by 11% to £424.7m ($634.4m).
