Black Country-based supplier Sandland Packaging is under new ownership following a £5.5 million investment.
The deal means Andy Sandland, the founder and majority shareholder, has left the Bilston-based business.
The new-look management team is led by husband and wife duo Martin and Jo Hickman, Andy Batha as sales director and Robin Welch as chairman.
Sandland Packaging was founded more than 30 years ago and specialises in the production of cardboard packaging for customers across the UK.
The firm's services include packaging design, manufacture and delivery through its fleet of lorries.
Mr Welch said: "This change of ownership marks the start of an exciting new chapter for Sandland Packaging.
"We are planning to build on the solid foundations laid by the previous owner and founder while pursuing emerging opportunities in the cardboard packaging sector driven by the rise in product shipping and the growing appeal of cardboard as a sustainable packaging option.
"We plan to expand Sandland's service and products for new and existing customers."
Funding of £2.6 million for the buyout was provided by Frontier Development Capital with a further £2.9 million from Independent Growth Finance.
Simon Kelsall, investment director at Frontier Development Capital, said: "As a leading national supplier of cardboard boxes, Sandland Packaging is well-positioned for future growth.
"The firm's experienced management team has the ability to provide a full-service offering to its customers from product design through to delivery.
"We look forward to working with the team over the coming years to deliver the opportunities ahead of them."
Paul Edmeades, director of asset-based lending at Independent Growth Finance, added: "We are delighted to be working alongside the new management team in what is a highly successful business.
"Our revolving and term facilities will give the business a strong financial platform to focus on future growth."
Advisers on the deal were BSN Chartered Accountants, Lodders Solicitors, Mazars, Shoosmiths and The Wilkes Partnership.
