Title: A method of, and apparatus for, leak testing a package ABSTRACT A method of, and apparatus for, leak testing a package, in which the package (6) is placed in a sheet-like, gas-tight envelope. A pressure differential is generated between the outside and the inside, as a result of which the package is closely enveloped by the envelope. This pressure differential is so large that it decreases the volume of the package and increases the internal pressure in the non-filled portion thereof. In the space (16) ("measuring space") between the package and the envelope pressed against it, a pressure is used which is lower than the increased pressure in the package. In the sealed measuring space, the change in pressure is measured for a pre-determined measuring period.
