    The best of plastic and paper in one material
    Paptic has invented a flexible packaging material made from wood fibre, that also provides beneficial plastic-like properties. Products made from this recyclable and bio-based material are designed for re-use, and it can be used to replace e.g. single-use bags, reusable shopping bags and e-commerce mailers. Its manufacturing process uses 20-30% less water than traditional paper-making processes.
