A squalinder that is a tube closed at both ends at a 90 degree angle that is perpendicular to the other end. The perpendiculube can hold a volume less than the capped cylinder of the same amount of material but can hold significantly more than the closed squared ends of a flat package.
The perpendiculube allows the most volume for packaging materials in a tube with only two seams, cutting costs and increasing durability.
