CKB Nude is a fully brown board with natural look and feel. Made from pure, fresh fiber, CKB Nude makes a safe choice for food packaging, also for on-the-go and quick service restaurants, and for a wide variety of other products like cosmetics. If you want a stiff and firm kraft board with an organic, artisanal appearance, CKB Nude is a good choice for your packaging.
Cupforma Natura is ideal for serving, packaging and enjoying food and drinks. Familiar from paper cups, but can be used also in packaging, for example for soups, chilled foods, ice cream, chocolate, even butter. Good formability into different shapes, lightweight yet firm for creative designs. Recyclable, sustainably sourced pure and fresh fiber, manufactured with certified processes and the best available techniques like all Stora Enso paperboards.
This fully brown board is for primary packaging of beverages and liquid foods typically sold in supermarkets. Keeps the contents such as milk, yoghurt, juice, spices, water, sauces and soups fresh, hygienic and unchanged while the printable surface delivers your message. Natura Life is a food-safe, unbleached board made of pure, fresh fiber from trees. Natura Life is approved for Nordic Ecolabel, a third-party verified proof for its environmental performance throughout the lifecycle of the product.
Tambrite and Tamfold are true all-round packaging materials, safe for food, pharma, chocolate and confectionery packaging, and adaptable to other end uses as well (not liquid). Tamfold is particularly good for on-the-go food packaging and quick service restaurants. Tambrite’s nice surface smoothness and brightness works fine with special finishing effects to give the package that final touch. Whatever you pack, these stiff folding boxboards will make highly attractive and tactile packaging.


You can decide what to pack. Choose a food product or any other fast-moving consumer goods, and think which material would fit best for your design. All these materials will be delivered to you if you are chosen to the top 50 who will be asked to submit a physical mock-up.
