The present invention relates to a returnable package a comprises confining elements ( 2 ) that can be mutually assembled in a removable manner to define a holding volume, said confining elements having interfacing surfaces ( 2 a) designed to be in mutual contact when two or more packages ( 1 ) are under piling-up and/or side-by-side relationship conditions; the package further comprises grip means ( 3 ) associated with the interfacing surfaces of the confining elements, the grip means being disposed in a matrix scheme defining directrices ( 4 ) intersecting at least two directions of possible relative sliding ( 5 ) that are mutually transverse and lie on the interfacing surfaces.
