Specialty paper is a category that includes everything from tea bags to bank notes and photographic paper. These different products bring their own special needs which are also highly varied, from stiffness and strength to porosity and opacity.
Metsä Fibre’s extensive product portfolio provides options for all these diverse needs. Our range of softwood pulps includes thin walled fibres with fast refinability, and coarse and long fibres with good reinforcement potential. Botnia hardwood grades consist of birch and eucalyptus pulps. Birch fibres provide good strength and surface properties while eucalyptus fibres provide good bulk, due to the rigidity of the fibre. The high fibre number gives good formation and surface properties, softness and uniform pore size distribution. On the other hand BCTMP will improve the bulk, stiffness and opacity of various paper products compared to chemical pulp.
