Before the thermoforming of a plastic sheet, a paper container corresponding to the outer shape of the container to be produced is inserted into the thermoforming mould. The paper container ensures the dimensional stiffness of the container and the plastic material ensures its leak-tightness. The container produced according to the process has a considerably reduced proportion of plastic material and the outer paper layer (16) of the container facilitates its decoration. <IMAGE> |
