Andrew Marshall, CEO of Nampak said "this acquisition is part of our strategy of investing in our core businesses where we believe we have competitive advantages.
"As a result, Nampak is looking to grow its glass operations in South Africa and the rest of Africa. This will be more easily achieved by us owning 100% of the glass business.
"Although they will no longer be shareholders in the business we are pleased that Wiegand-Glas have agreed to remain as our technical service provider."
The transaction is subject to the approval of the Competition Authorities.
