Elsewhere, DS Smith said the project to commission the lightweight corrugated case material machine at the company's New Thames mill in Kent remains on schedule. The mill was acquired from M-real for £60m in February this year.

Its results for the six months to 31 October 2008 will be announced on 3 December.
