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 flexibility yet rigidity to be used in such tube-formed containers.
