ABSTRACT A method of producing a package is provided wherein a product is brought into a depression formed using a shrinkable sheet material, a cover is brought over the depression, the sheet material is shrunk by heating and the depression is closed with a cover by heat-sealing. In order to shrink the depression free from creases onto different and irregular product surfaces steam is admitted to the sheet material having a saturation temperature above the sheet material temperature such that the steam condensing at the sheet material transfers its heat of condensation to the sheet material. The apparatus for performing the method comprises a sealing station with an upper tool and a lower tool movable relatively thereto and having a chamber for receiving the depression, the chamber being connected with a steam generator.
