Abstract
A manufacturing process for producing hermetic single-use food containers includes: forming a 3D container body having a peripheral upper rim by stamping a 2D blank in a press, the 2D blank including a rim portion and a wall portion; applying a closing lid over the 3D container body and sealing the closing lid with the rim. The manufacturing process is characterized in that it comprises a creasing step before forming the 3D container body, where creases are formed in a peripheral zone of the 2D blank by creasing or embossing the 2D blank with a creasing or embossing plate, the thus pre-creased peripheral zone covering at least a part of the rim portion of the 2D blank.
