Abstract: A method for packaging a good by means of a package formed of a shrinkable lower film 7 and an upper film 10 is provided. The lower film may be deep-drawn to form a container for accommodating the good, and after filling in the good, an upper film may be supplied for covering. The such-formed package is sealed and then may be subjected to shrinking in an evacuating and sealing station. Consecutively to the evacuating and sealing, an additional shrinking may be performed by subjecting the package to heat from all sides, so as to remove the film section having developed between the part of the lower and the upper film directly resting against the good and the sealing rim 16. A corresponding device for executing the method is indicated.
