Nampak Plastics managing director Eric Collins said: "This is a very exciting time for Nampak. For the last six years, the team has been focused on continuously innovating and pushing boundaries where possible with Infini, and this is now showing exceptional tangible results, reducing the carbon footprint of the plastic milk bottle." Marks & Spencer commercial and environmental packaging manager Andrew Speck added: "Since Nampak helped us launch the first milk bottles with post-consumer recycled content in 2007 it has continued to deliver innovative packaging solutions for us, most recently this year's 30 per cent recycled content bottles that we are currently trialling. "Nampak continues to push the barriers around performance and sustainability, and we look forward to working with it on more ground-breaking innovations into the future."
