Different pulp grades
The length and strength of fibres vary depending on the wood species. Therefore, pulp grades have properties suitable for different end uses. Softwood pulp consists of long fibres, giving strength, while hardwood pulp consisting of short fibres, gives excellent surface properties. Different pulp grades are often mixed, particularly in the production of paperboards.
BCTMP (bleached chemi-thermomechanical pulp) is bleached chemical pulp. Its manufacture combines mechanical and chemical pulping processes for removing the fibres. For example, in the production of folding boxboard, the middle layer of paperboard is BCTMP, which makes the board light but yet stiff.
