Products
Muoto Twin Uncoated Fibre Series
Muoto Twin Uncoated Fibre products are untreated, smooth, molded fiber items made from renewable wood fiber sourced from Nordic forests. The products are plastic-free and manufactured without added PFAS, yet remain water- and grease-resistant for use in food service and take-away. Thanks to new technology, internal barrier properties and a multilayer structure are achieved, enabling lightweight design, strength, and stability—all key quality attributes. The products are recyclable, biodegradable, and approved for food contact. Our supply chain is fully transparent and traceable. Muoto Twin products have a distinctive design that can be scaled to different shapes and sizes. The current product portfolio includes formats such as plates, bowls, and clamshell packaging. The new manufacturing method is highly resource-efficient, modular, and fully automated. Production can be integrated into a bioproduct mill, and Muoto Twin products require no additional processing later in the supply chain. They can be used by industry, food service, and households alike. Made from renewable Nordic wood fibre, Muoto Twin combines simplicity and design with innovative functionality. Whether used as a single item for serving or paired as a closable unit for take-away, it offers a flexible and sustainable packaging solution for modern food service needs.
