The £63m-turnover Midsomer Norton-headquartered group has achieved the BRC standard for packaging and packaging materials, category 2, at its labels operation in Farrington Gurney.
The move caps a £1m investment programme at the division, which included the addition of a Xeikon digital press last year and a six-unit Gallus press in January.
The BRC standard is focused on hygiene, and Integrity described it as a "business critical objective" for the company, as it was becoming a must-have for some of its clients. Integrity has already achieved ISO9001 and ISO14001, and the information security standard ISO27001.
