It has also got the deal past French works councils, which means that part of the business should be sold at the same time as the rest of SCA, the company said.
It aims to complete the takeover at the end of June 2012.
"We are delighted with the support for the transaction given to us by our shareholders and I am pleased to report that the process towards completion is on track," said Chief Executive Miles Roberts.
In terms of sales, Smith said like-for-like volume growth in corrugated packaging for the financial year to date was in line with its target of GDP+1%.
This was driven by a consistent performance among the company's fast moving consumer goods customers, with a strong contribution from its business in Continental Europe.
Smith's said it continued to reduce working capital and anticipated achieving its target of average working capital-to-revenue of 5% at the end of the year, compared to 6.4% last year.
The return on average capital employed for the year was expected to be within the company's target range of 12 to 15%, compared to 11.5% the previous year, the firm said.
