Abstract (en)
The invention concerns a ligno-cellulosic-material-based product and a manufacturing method thereof, in which method the product is formed from multiple plies of cellulosic fibers into a multi-ply product comprising a liner ply and at least one center ply interleaved between the liner plies. The invention is characterized by having said at least one center ply of the multi-ply product enriched with thick-walled summerwood fibers, and further having the liner ply of the multi-ply product advantageously enriched with thin-walled and/or band-shaped springwood fibers.
