forming a plurality of troughs in a bottom film in a forming station;

supplying a plurality of frames to the bottom film, the number of frames corresponding to the number of troughs formed;

sealing the frames onto the bottom film in a first sealing station; and

sealing a cover film onto the frames or the bottom film.

2 . The method according to claim 1 , wherein the sealing of the cover film takes place under a vacuum and/or modified atmosphere and produces a gastight reclosable package.

3 . The method according to claim 1 , wherein the frames are unwound from a roll in the form of a webshaped material with openings, and supplied to the first sealing station.

4 . The method according to claim 1 , wherein a punching station of a thermoform packaging machine produces the frames from a full-area, webshaped material.

5 . The method according to claim 1 , wherein a soft film having a maximum thickness of about 200 μm is used as a material for the bottom film.

6 . The method according to claim 1 , wherein a hard film having a minimum thickness of about 300 μm is used as a material for the frame.

7 . The method according to claim 1 , wherein the frames and the bottom film are inseparably sealed to one another.

8 . The method according to claim 1 , wherein, in the first sealing station, the cover film together with the frames and the bottom film are sealed onto one another.

9 . The method according to claim 1 , wherein the cover film is sealed onto the frames in a second sealing station, after the frames and the bottom film have previously been sealed onto one another in the first sealing station.

10 . The method according to claim 1 , wherein the frames are sealed onto a lower side of the bottom film.
