Abstract
A thin-wall deep drawn container having a molding depth vs. aperture caliber ratio of 2.0 or more, having a mean wall thickness of 0.1-0.6 mm at the sidewall and bottom of the hollow part and having a flange part of 1.4 mm or less in thickness at the aperture end can be produced from a thick sheet of a thermoplastic resin, preferably a crystalline plastic, having a thickness of 2 mm or more by plug-assist pressure forming.
