A new sustainable packaging technology has been developed by VTT Technical Research Centre of Finland, Aalto University, and domestic industrial partners to shape cardboard into origami-inspired structures.
The origami folds endow cardboard with entirely new properties, enhancing its lightweight nature and durability in fibre-based packaging.
These features present an alternative to conventional protective packing materials such as plastic and expanded polystyrene while also improving their aesthetic appeal.
The FOLD and FOLD2 projects, involving 13 companies and universities, are seen as pivotal in redefining the use of cardboard as a packaging material.
The first phase saw the design of a machine capable of folding origami cardboard, with the subsequent phase testing additional materials.
The success of these projects has led to novel applications of cardboard, creating packaging that is not only flexible and durable but also sustainable.
VTT FOLD project creator and research team leader Jarmo Kouko said: "The technology of FOLD is completely unique in the world. Origami folding transforms cardboard into a flexible, protective, and visually appealing material unlike anything that’s previously been available for industrywide production. The technology we’ve developed also has the capacity to produce foldable materials from recycled goods.
"The Japanese Miura origami pattern we’ve chosen is relatively simple, which makes it potentially suitable for folding many other materials. We have investigated the possibilities of developing techniques and models where felt or film made from PET, widely used in plastic packaging, could be shaped in the Miura form. We’ve also performed some preliminary testing for other materials, such as aluminium foil.”
Stora Enso R&D manager Jari Räsänen added: "The packaging industry is very interested in FOLD, and close cooperation with various enterprises enables us to move quickly from the innovation phase to practical application. We could see origami cardboard on the market within 3-5 years if the project progresses as planned."
Stora Enso, a Finnish packaging company, is one of the companies involved in the project.
In August this year, VTT launched the €20m ($22m) Energy First project to cut energy use in fibre product manufacturing.
