To provide a vacuum packaging method and a vacuum packaging apparatus that can sufficiently degasify the inside of a packaging bag without any trouble and in which bubbles are less likely to remain inside the packaging bag after vacuum packaging, even if a liquid is included in a packaged object. In the vacuum packaging method in which the packaged object including the liquid having a temperature that is higher than a normal temperature is vacuum packaged with a packaging bag B, the packaged object is vacuum packaged by a package decompressing process in which, after a chamber 2 is decompressed inside to a second set pressure P2 that is set in advance, a packaged-object filling opening Ba is closed inside the chamber 2, and in this state, the chamber 2 is decompressed inside to a third set pressure P3 that is lower than a second set pressure P2; by a closing cancellation process in which, after the package decompressing process, cancels a closed state of the packaged-object filling opening Ba inside the chamber 2; and by a sealing process in which, after the closing cancellation process, closes the packaged-object filling opening Ba again and seals the packaged-object filling opening Ba in the closed state. |
