Hodges said staff at the company's Bristol site, which resumed production at the end of August to fulfil client orders, were holding up fairly well and were upbeat about the interested parties; however, they were concerned that they didn't know more details about the potential buyers.

"The Bristol-based site is working on a week-by-week basis on orders that are coming in," he said. "The issues are still ongoing – two more of our members were made redundant recently, meaning six members of staff at the site have been affected so far."

Hodges added that, initially, some 29 parties were interested in the £23.7m-turnover company.

Grant Thornton UK partners Alastair Wardell and Daniel Smith were appointed joint administrators of CPC Packaging UK and its operating subsidiaries on 25 August. A spokesman said there was no update on the situation at present.

When it went into administration, 95 CPC staff were made redundant, largely from the site in King's Lynn, Norfolk.

According to accounts filed at Companies House for the year-end 2008, combined staff at the two sites in 2008 was 162.

Turnover at the King's Lynn operation was £12.3m, on which it made a pre-tax loss of £642,000, with Bristol generating £11.4m sales and a £188,000 loss.
