PROBLEM TO BE SOLVED: To provide an occlusion material for a grove port capable of reducing the waste. SOLUTION: This sheet-shaped occlusion material 1 for the grove port of a glove box has a base material layer 3 used as a base material positioned on the surface side, a bonded layer 5 positioned on the opposite face side to the base material layer 3 and bonded to the grove port of the glove box by thermo-compression bonding, a permeation blocking layer 7 positioned between the base material layer 3 and the bonded layer 5, for blocking permeation, and a perforation resistant layer 9 positioned between the bonded layer 5 and the permeation blocking layer 7 and having resistance against mechanical perforation. Since the occlusion material 1 for the grove port can occlude airtightly the insertion port part of the glove port and also has the sheet shape formed by a laminate film, the bulk and the weight can be reduced in comparison with an airtight inner ring having a conventional structure. Hereby, when treated as the waste, the bulk and the weight of the waste can be reduced in comparison with the airtight inner ring having the conventional structure, to thereby reduce the waste.
