Natural Brown Board Carton from Elopak: Launched in 2017, in partnership with supplier Stora Enso, Elopak was the first packaging company to provide gable top cartons made with Natural Brown Board. These Pure-Pak® cartons are renewable and recyclable. They have a lower CO2 footprint owing to reduced wood consumption and the elimination of the bleaching process. Their rustic, natural look effectively communicates this commitment to sustainability and instantly stands out on the shelves. Natural Brown Board is available in both our Pure-Pak® Sense and Pure-Pak® Classic cartons and is the foundation of the Pure-Pak® Imagine – our most sustainable carton to date. Natural Brown Board comes in all fill-sizes and cross-sections – from 250ml to 1l – and can be combined with all our optional environmental features to create the most sustainable packaging solution for you.
