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.

Abstract: The invention discloses a method for manufacturing a multiply paperboard comprising the steps of:- forming a web comprising at least a top ply, a back ply, and a middle ply arranged between the top ply and the back ply, wherein the middle ply is formed from a first furnish comprising at least 50 wt% of a HT-CTMP and 0.1 - 10 wt% of glue pulp based on the total dry weight of said first furnish, wherein said glue pulp has a Schopper Riegler (SR) value in the range of 55- 84 as measured according to standard ISO 5267-1 and a mass fraction of fines of less than 25% as measured according to standard ISO 10376:2011,- subjecting the thereof formed three-ply web to pressing in at least one shoe press, and- drying the web.It has been found that the combination of using the said furnish mixture including HT-CTMP and glue pulp with an SR value within said range enables efficient dewatering by use of a shoe press and gives rise to a paperboard with high bulk but maintained or improved strength properties.
