Kuitupohjaiset

Kuitupohjaiset is a Finnish term used to describe materials and products whose primary constituent is plant-based cellulose fiber. The category covers a wide range of items, from traditional paper and cardboard to nonwoven fabrics and certain fiber-reinforced composites. Fibers may originate from wood pulp, recycled paper, or other plant sources such as cotton, hemp, flax or bamboo.

Production of fiber-based materials involves separating and refining fibers through pulping or refining processes, followed by forming sheets for paper and cardboard or creating nonwoven webs and spun filaments for textiles and composites. Some products are treated with coatings or barrier layers to improve performance, though such treatments can affect recyclability.

Applications are diverse. Packaging and consumer goods commonly use fiber-based materials in cardboard and paper packaging. In construction, fiber cement and wood-based composites are examples of fiber-based products. Insulation and soundproofing rely on cellulose or other plant fibers. In textiles, cellulose-derived fibers such as viscose, lyocell and modal are widely used, while engineered composites employ natural fibers as reinforcement.

Environmental considerations emphasize renewability, recyclability in paper and board streams, and biodegradability under appropriate conditions. The sustainability profile depends on fiber sourcing, processing methods, and end-of-life infrastructure. Certifications like FSC or PEFC are often cited to indicate responsible forest management and supply chain stewardship. Challenges include moisture sensitivity, mechanical strength, and the impact of coatings or additives on recyclability and compostability.
