Abstract: The present invention discloses a high quality multi-ply paperboard. The invention is characterized in that the middle ply of the paperboard comprises at least 50 % of high -temperature chemithermomechanical pulp (HT-CTMP) from hardwood fibers, calculated on the total fiber weight of said middle ply. It has surprisingly been shown that the use of HT-CTMP from hardwood fibers in the middle ply enables the production of a paperboard with a very high bulk and with maintained strength properties. Moreover, the use of HT-CTMP from hardwood fibers significantly improves the brightness properties and the formation of the paperboard.
Abstract translation: 本发明公开了一种高质量的多层纸板。 本发明的特征在于，纸板的中间层包含硬木纤维的至少50％的高温水泥机械纸浆（HT-CTMP），以所述中间层的总纤维重量计算。 已经令人惊讶地发现，在中间层中使用来自硬木纤维的HT-CTMP使得能够生产具有非常高的体积并具有保持的强度性质的纸板。 此外，硬木纤维的HT-CTMP的使用显着提高了亮度性能和纸板的形成。

Abstract: The invention discloses a container for the packaging of compositions comprising water water-in-oil (W/O) emulsions and/ or oil-in-water (O/W) emulsions, which container comprises a tube-formed body made from a paperboard comprising a fiber based substrate comprising a first ply forming a back ply, a second ply forming a top ply and a third ply forming at least one middle ply, wherein the fiber based substrate comprises CTMP. The compositions comprising W/O or O/W emulsions may be semi-solid compositions. The invention solves the problem of delamination of the multi-ply board connected to prior art solutions. In addition, the container provides the specific barriers needed to pack compositions comprising W/O- or O/W- emulsions. It further provides the required flexability yet rigidity to be used in such tube-formed containers.
