Supporting ambitious sustainability goals

UPM partnered with EvoPak to support Walkers Chocolates transition from a plastic wrapper to recyclable paper-based packaging. This will help Walkers Chocolates achieve its sustainable packaging ambition while reducing plastic usage across their site. Walkers Chocolates products which are packed in the solution are already available across multiple UK retail chains and international markets.

The perfect solution for packaging chocolates

The partnership combined UPM Solide Lucent 45 g/m² barrier base paper with EvoPak's RCM coating – a unique, water-soluble polymer. And the results were as sweet as we hoped for. The breakthrough fibre-based barrier solution maintains the functional benefits of traditional plastic packaging while maintaining recyclability, making it perfect for chocolate and other demanding uses.

"The printability of UPM Solide Lucent is really impressive and Evopak’s RCM coating is a revolutionary solution for our industry. We've achieved the same packaging line efficiency, maintaining the same speed as our previous plastic packaging materials with only minor adjustments."
Tom Murtagh, Commercial Director, Walkers Chocolates

Sustainability comes built in

With a unique look and feel, UPM Solide Lucent is a strong and extremely versatile barrier base paper. A smooth surface and high strength density offer superior properties for further converting and printing while enabling choosing minimal coating weights.

The packaging sustainability credentials are as impressive as its performance, supporting the circular economy and complying with upcoming PPWR recyclability requirements. The co-created solution with EvoPak's RCM coating and UPM Solide Lucent barrier base paper has achieved CEPI/4EG Technical Recyclability Score (v. 2.0 Jan 2025).

"We're extremely happy with how the paper extrudes and the print quality in flexo is exceptional. We are 100% happy in UPM Solide Lucent as the grade of choice for our future.”
Tom Lock, CEO, EvoPak
