Abstract: A package closure system has a frangible radiofrequency identification label which is protected from the external environment by a cover and the frangible label is damaged preventing its normal operation when the package cover is removed. More specifically, a package closure system has a cover, a metallic induction seal attached to the package nozzle and a frangible radiofrequency identification label in which the frangible radiofrequency identification label is attached directly or indirectly to one of its parts on the inner portion of the cover and on another part on the outer portion of the metallic seal.

Abstract: Package closing system and package authentication system comprising cover (4), seal (3) attached to the package nozzle (2) and “frangible” type radiofrequency identification label (6), characterized by the “frangible” type radiofrequency identification label (6) to be attached directly or indirectly to one of its parts on the inner portion of the cover (4i) and on another part on the outer portion of the seal (3e), so that the opening of the cover (4) leads to the destruction of the “frangible” type radio frequency identification label (6).
