PURPOSE:To eliminate an apprehension of leakage of content even if substance absorbing odorant is used as a cover of a polypropylene or aluminum vessel used to contain the substance by coating all or part of one side face of an aluminum foil with modified polyolefin adhesive not corroded by the odorant of various states. CONSTITUTION:As an adhesive to coat an aluminum foil 1, modified polyolefin adhesive 2 not corroded with substance absorbing solution odorant, solid odorant, both solution and solid odorants is employed to coat one side face of the foil 1, thereby rigidly apply it to a polypropylene vessel 5.
