Disclosed is an automatic method for characterizing and/or sorting packages, in particular bottle-type containers or similar, moving in a substantially planar flow and substantially without overlapping or mutual superpositioning, the flow including monolayer and multilayer packages (1). The method involves introducing a liquid fluid, in particular water or a liquid made from water, between the non-integral layers of the multilayer packages, detecting the presence of this interstitial liquid fluid in the multilayer packages using a contact-free detection system, and using the resulting information to characterize and/or sort the two types of packages (1). |
