Filtrona, the maker of cigarette filters and other fibre and plastic products, has seen continued strong demand in the third quarter. Revenue for the period was up 10% compared the same period last year. Net debt stood at £80m at 1 October, a £2m reduction since end-June, benefiting from continuing strong operating cash flow. The firm's protection and finishing products continued to see broad-based growth, but the performance in porous technologies was affected by a moderation in customer demand during the period, which is anticipated to recover, the group said. "With year-to-date revenue growth of +10% at constant exchange and +8% on a like-for-like basis, the company has continued to see positive momentum. As a result, while mindful of the current economic uncertainty, we are well-positioned to deliver balanced growth for the remainder of 2011 and into the next financial year," chief executive Colin Day said. The share price was up 4.64% at 354.1p at 10:05. NR
