(B)CTMP

High-quality CTMP and BCTMP from MM Board & Paper, optimised for every application from cartonboard to tissues.

MM BOARD & PAPER PRODUCT

About (B)CTMP

Our Norwegian mechanical pulp mill MM FollaCell produces chemi-thermomechanical pulp from logs and wood chips, both in the unbleached variant (CTMP – chemi-thermomechanical pulp) and bleached variant (BCTMP – bleached chemi-thermomechanical pulp). This special process results in particularly high-quality mechanical pulp, which also has some of the beneficial properties of chemical pulp – such as the tear strength of the products made from it. The wood chips are first chemically pre-treated and then heated with hot steam before they are refined. Through double screening, MM FollaCell can offer one of the cleanest (B)CTMP. Depending on the type, pure softwood, pure hardwood or a mixture of softwood and hardwood is used – all from sustainable forestry.

The pulp is used in the MM Board & Paper mills and also sold on the international market.

Technical details

Engineered for strength, stiffness and production efficiency

FollaCell SW grades are produced from responsibly sourced Nordic softwood fibres and are designed to enhance strength, stiffness and bulk.

Their optimised long-fibre composition enables efficient fibre utilisation, reliable runnability, and lightweight product design. A strong long-fibre network provides excellent stiffness and bulk, supporting demanding converting and end-use requirements.

Outstanding cleanliness, low shive content, and low levels of extractives contribute to stable processing conditions, improved machine efficiency, and consistent product quality.

As a result, these grades are an ideal choice for applications where mechanical strength, process reliability, and production efficiency are key performance drivers.
FollaCell also offers speciality grades and trial runs tailored to customers’ specific production requirements.

A balanced solution for versatile paper and board applications

FollaCell SW/HW grades provide a well-balanced combination of strength, bulk, opacity, and surface properties, making them suitable for a wide range of paper and board applications. Their complementary fibre characteristics enable efficient fibre utilisation while helping manufacturers achieve targeted product performance and process efficiency.

Combining softwood and hardwood provides manufacturers with the strength and stiffness of a softwood long-fibre network, together with the excellent formation, surface quality and optical properties of hardwood fibres. This balanced fibre composition offers flexibility in product design while supporting performance, runnability, and resource efficiency.

FollaCell also offers speciality grades and trial runs tailored to customers’ specific production requirements.
