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 is deep-drawn to form a container for accommo-dating the good, and after filling in the good, an upper film is supplied for covering. The such-formed package is sealed and at the same time subjected to shrinking in an evacuating and sealing station. Consecutively to the evacuating and seal-ing, an additional shrinking is performed by subjecting the package to heat from all sides, so as to remove the film sec-tion 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 in-dicated.
L'invention concerne un procédé d'emballage d'un produit au moyen d'un emballage formé d'un film inférieur (7) rétractable et d'un film supérieur (10). Le film inférieur est embouti pour constituer un réceptacle destiné à recevoir le produit, et, après introduction dudit produit, le film supérieur est amené pour former un couvercle. L'emballage ainsi formé est scellé par retrait dans une station de mise sous vide et de scellement. Pour que la partie de film formée entre la partie du film inférieur et du film supérieur reposant directement sur le produit et le bord de scellement (16) soit éliminée, on procède ensuite, après la mise sous vide et le scellement, à une post-rétraction en soumettant tous les côtés de l'emballage à de la chaleur. L'invention concerne également un dispositif permettant la mise en oeuvre de ce procédé.
