In partnership with Aalto University and Finnish industrial collaborators (see below), VTT has introduced groundbreaking technology for shaping cardboard into origami-inspired structures through a continuous reel-to-reel process. This advancement offers sustainable and visually appealing alternatives to traditional protective packaging materials like plastic and expanded polystyrene.
The global demand for environmentally friendly packaging has grown with the rise of e-commerce and concerns about microplastic pollution. The FOLD and FOLD2 projects, involving 13 companies and universities, aim to expand the versatility of cardboard. The first phase successfully developed a machine to create intricate, durable, and lightweight cardboard folds, while the second phase explores applications with diverse materials.
Jarmo Kouko, the project’s creator, emphasizes that the folding technique mirrors hand-crafted origami but achieves industrial precision and scalability.
Inspired by the Japanese Miura folding pattern, the technology can process various paperboard grades and even recycled materials. Early testing has also explored potential uses for materials like PET film and aluminum foil.
The innovation has garnered industry and design community interest. Demo products showcased at design events highlight its aesthetic appeal, particularly for luxury packaging. With global commercialization anticipated within five years, FOLD technology promises to revolutionize packaging with sustainable and versatile solutions.
Note: In addition to VTT and Aalto University, the FOLD project involved Anpap, Business Finland, Elomatic, Lumene, Metsä Board, Mirka, Orfer, Soften, and Stora Enso. The FOLD2 project involves VTT, Aalto University, Anpap, Business Finland, Marja-Suomen Taimituotanto, Mirka, Soften, Stora Enso, and Walki.
