Process for manufacturing cellular structure based on a composition comprising an amorphous thermoplastic polymer and made up of sheets extruded in parallel and intermittently welded, according to which: an amorphous polymer composition is chosen which has a dynamic melt viscosity, measured at its processing temperature and at an angular velocity of 0.1 rad/s, of less than 2000 Pa.s; and the temperature of the coolant is regulated so that it is at least equal to TSUBg/SUB-20° C., where Tg is the glass transition temperature of the composition based on the amorphous polymer.
