Since its launch in 2012, sales of the Infini bottle have continued to soar, and it can now be found in a number of major retailers including Marks & Spencer, Morrisons, Sainsbury’s, Tesco and Waitrose.

Infini is, currently, the lightest and strongest bottle on the British market. It has saved 34,000 tonnes of carbon and 16,000 tonnes of material per year since 2012, while Nampak’s design and engineering teams are always working on further innovation.

Eric Collins, Managing Director of Nampak Plastics, commented: “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

“The half a billion mark is a significant milestone – we couldn’t be prouder of our accomplishments so far, and we look forward to continued growth ahead.”

Andrew Speck, Commercial and Environmental Packaging Manager at Marks & Spencer also commented “Since Nampak helped us launch the first milk bottles with post-consumer recycled content in 2007 they have continued to deliver innovative packaging solutions for us, most recently this year’s 30% recycled content bottles that we are currently trialling. Nampak continue to push the barriers around performance and sustainability and we look forward to working with them on more ground-breaking innovations into the future.”

In the last 12 months alone, Nampak has achieved two world records with the Infini bottle. The company trialled, tested and supplied the first four-pint milk bottle containing up to 30% rHDPE. This breakthrough came just weeks after Nampak created a four-pint Infini bottle weighing in at just 32g, representing a 20% material saving on the standard four-pint version found in supermarkets today.

Successes to date have seen Infini claim a number of industry awards, including some on a global scale, with a silver prize for sustainability at the coveted WorldStar Awards, and winning Green Product of the Year at the British Engineering Excellence Awards in 2013.
