Abstract
A laminated packaging material is composed of a thermoplastic material outermost layer, a paper base material layer, a conductive barrier layer and a heat sealing innermost layer. An apparatus inspects an opening section, which is formed by at least partly eliminating the thermoplastic material outermost layer and the paper base material layer and by being sealed to be easily opened. In the apparatus, a probe electrode and a grounding electrode are arranged on the outer side and the inner side of the opening section, a current flowing between the probe electrode and the grounding electrode is detected by using the conductive barrier layer, and the sealing status of the opening section is inspected by a judging mechanism.
