A method and work station (SV) for checking the integrity of packages (), in particular single-dose packages uses a first pressing device () for applying a reference force to one or a group of packages () for a predetermined time interval (Dt). The value of the force transmitted by the package () is detected using one or more load cells (6) positioned opposite to the first pressing device () with respect to the package (). The load cells detect the force transmitted through the package. Packages are rejected when the value of the force transmitted by the package () is lower than a critical force value (f*) which is a value of the force transmitted to the load cells by a good package. Before using the first pressing device for applying the reference force, a second pressing device is used to apply a test force to the package () for a time interval (Dt*) for preliminarily stressing the package () before the load cells detect the value of the force transmitted by the package () in response to the force applied by the first pressing device.
