Wool, as a natural insulating material, performs extremely well when utilised in cool-chain packaging. Wool is hydroscopic in nature, and therefore absorbs excess moisture, supports structural integrity of the package, and provides mechanical cushioning during the journey. The Wool Liner is compostable, so can be added to your garden in disposal. As the wool fibres are closely woven, there is better capture of air inside the carton. Wool Liners reutilise wool offcuts and repurpose what would be a waste product.
