We produce Metsä Birch Bleached Hardwood Kraft Pulp (BHKP) and Bleached Chemi-Thermo Mechanical Pulp (BCTMP), primarily from birch hardwood. The hardwood content used in our BHKP and BCTMP is mainly birch, which is abundant in Nordic forestland. Nordic birch wood is known for its unique chemical and physical characteristics, providing excellent end product qualities. With our hardwood pulp, we ensure that our customers achieve strength and surface quality in their paperboard, printing paper, and tissue products. The wood we use is traceable and comes from sustainably managed forests.
Hardwood properties ideal for demanding paper end uses
Hardwood refers to wood from deciduous and broad-leaved trees, with birch being abundant in the northern forests. Birch is known not only for its almost white bark but also for its high density and strength, thanks to its short wood fibres. The pulp made from birch hardwood is especially preferred in paper applications requiring durability, tensile strength, smooth surface texture, and absorptivity. Furthermore, pulp fibres of hardwood trees make it possible to achieve higher brightness, excellent opacity, and greater bulk in paper manufacturing. Metsä Fibre’s hardwood pulp properties deliver high quality for applications in the global paper-making market.
Bleached Hardwood Kraft Pulp (BHKP)
Bleached Hardwood Kraft Pulp (BHKP) is commonly used in paperboard and specialty paper, as well as in coated and uncoated papers and tissue. In many applications, hardwood pulp provides excellent physical strength, smoothness and surface properties due to its chemical and physical fibre structure.
Our hardwood pulp is used to make our Metsä Birch branded BHKP products. We produce high-quality hardwood pulp from birch at our bioproduct mills in Äänekoski and Kemi in Finland and at Metsä Board’s Husum mill in Sweden.
Our hardwood pulp consists of high-quality Nordic birch (Betula verrucosa, Betula pendula or Betula pubescens), sustainably sourced and felled by Metsä Forest. The wood we use is traceable. Our hardwood kraft pulp made from Nordic birch is ideal when high tensile strength and good formation is required.
High yield pulp (BCTMP)
Our Bleached Chemi-Thermo Mechanical Pulp (BCTMP) is often utilised in the production of paperboard to provide higher bulk and stiffness. In printing papers, for example, higher brightness, bulk and smoothness can be achieved by replacing mechanical pulp with BCTMP.
Our BCTMP pulp is used to make our High Yield TENSILE, BULK and SUPER BULK products. We offer these products in cooperation with Metsä Board and produce them at Metsä Board’s Kaskinen mill in Finland.
What gives Metsä High Yield Pulp its excellent high yield and paper technical properties is the bleaching process, which has been designed to keep the wood’s natural lignin intact. Each Metsä High Yield Pulp is customised to suit specific end uses, from coated specialty papers to board and tissue.
Both of our TENSILE and SUPER BULK pulp products consist of hardwood (primarily birch) and softwood (spruce). Whereas, our BULK product consists of only hardwood. The wood we use is traceable.
