Unlike many competitors, Papacks is not going down the route of a plant-based PET or polymer liners. Instead it is aiming to produce a fully plastic-free, compostable or kerbside paper recyclable item – that covers not just the bottle but the cap, closure and label too. Its recent collaboration with Keurig Dr Pepper shows the appetite from big brands and, while many challenges remain, we love its uncompromising plastic-free ambition.
