Abstract

A deep-drawing packaging machine (1) includes a forming station (2) for forming containers (14) in a first web-like material (8), an insertion section (15) for inserting products (16) which reach at least one sealing level (28) or project over it, and a sealing station (3) arranged downstream thereof in a working direction (R) which is embodied to seal a second web-like material (10) onto the containers (14). The packaging machine further includes a means (11) for changing a distance (12) of layers (10a, 10b) of the second, at least two-layered web-like material (10). In another embodiment, a packaging machine includes an insertion section (15) and a sealing station (3) arranged downstream thereof in the working direction (R), in which at least one contact (25) is provided for thermal transfer via heat conduction between a sealing plate (22) and a heating plate (23) for heating a lid foil (10).
