Abstract: La invención se refiere a una capa de un cartón de revestimiento para cartón corrugado, cuya capa muestra propiedades de alta resistencia y que permite la producción de cartones de revestimiento livianos. La capa de la invención comprende 20 - 80 % en peso de CTMP de fibras de madera y 80 - 20 % de pulpa química, calculado sobre el peso total de la fibra de dicha capa y los aditivos de resistencia elegidos del grupo de la celulosa microfibrilada (MFC), polímeros aniónicos o catiónicos y almidón o combinaciones de los mismos. La capa presenta un índice geométrico SCT superior a 22 Nm/g y una densidad inferior a 680 kg/m3, de preferencia inferior a 650 kg/m3.

Abstract: The invention relates to a method to produce a linerboard exhibiting a high bending resistance and a high compression strength, which in turn provides high resistance to interflute buckling and sagging in a thereof formed corrugated board. This is achieved by the inventive combination of an optimized fiber refining level of the furnish in each layer of the linerboard, the separate formation of the top layer and the use of a multi-layer headbox to form the two-layered ply. In addition, the linerboard made according to the invention provides good printing properties in a thereof produced corrugated board, especially in flexographic printing, without the fluting structure being negatively affected.

Abstract: The invention relates to a ply of a linerboard for corrugated board, which ply exhibits high strength properties and which enables the production of lightweight linerboards. The ply of the invention comprises 20 -80 wt pcnt CTMP from wood fibers and 80 -20 wt pcnt chemical pulp, calculated on the total fiber weight of said ply and strength additives chosen from the group of microfibrillated cellulose (MFC), anionic or cationic polymers and starchor combinations thereof. The ply exhibits a geometric SCT index of above 22 Nm/g and a density of below 680 kg/m3, preferably of below 650 kg/m3.
