About Interlok Divisions

Interlok Divisions Ltd has a long history with McLaren Packaging having been founded in 1985 by Jim McLaren before being brought back into the McLaren Packaging family of companies in 2019.

The story of McLaren Packaging

The McLaren Packaging story started with the vision of Jim McLaren and continues today, with the second generation, as a strong family of businesses which are 'Created with Experience', 'Inspired by Innovation' and 'Sustainable. For Life'.

In 1979, Jim McLaren founded McLaren Packaging with a clear ambition to become a specialist, independent supplier of paper-based packaging to the UK drinks sector. Through foresight and entrepreneurial vision, McLaren Packaging crafted a long-standing reputation for innovation, quality and service.

This allowed the business to grow organically, and acquire different specialist packaging companies, developing the internal expertise and knowledge to make McLaren Packaging the highly regarded and well respected organisation that it is today.

With premises in Port Glasgow, Inverclyde since inception, starting with one factory, and now consisting of four production facilities, the location has allowed McLaren to offer a successful One Stop Purchasing service to global brands.

McLaren Tubes, McLaren Corrugate and Interlok Divisions are all based in Port Glasgow today, with Blue Box Design in Stirling and Compack Cartons in Livingston, the group has production facilities across the central belt in Scotland.
