A graphene ribbon fiber manufacturing process, where a coagulation medium flows in the same direction as the graphene ribbon fibers. The process for spinning graphene ribbon fibers starts with unzipping carbon nanotubes to form graphene ribbons, purifying and drying the graphene ribbons and subsequent dissolving of the graphene ribbons in a suitable solvent, preferably a super acid to form a spin-dope. The spin-dope is spun such that the accrued fibers are guided into a coagulation medium, also known as anti-solvent, where the spun or accrued fibers are coagulated. The coagulated graphene ribbon fibers are stripped, neutralized and washed and wound on bobbins.

Metal body for packaging purposes comprising a closed metal shell extending around a longitudinal axis which is suitable for being provided on a side named here as the top with a lid running essentially perpendicular to the longitudinal axis. A transverse cross section through the shell on and close to the top has a contour comprising 3&lE;n&lE;6 contour line pieces that are curved concavely inwards with a minimum radius of curvature R, and n essentially straight contour line pieces. The shell also comprises at least n essentially flat shell parts, which are separated from one another by a sharp fold running essentially parallel to the longitudinal axis, which fold has a maximum radius of curvature r, whereby r&lE;0.4 R.
