PURPOSE: To more well keep the aroma or flavor of an enclosed substance by allowing the layer assembly positioned inside an intermediate barrier-effect layer to have a total thickness within a specific thickness range. CONSTITUTION: A skirt mainly includes a barrier-effect polymeric intermediate layer 20 between oxygen and aroma or flavor and the intermediate layer is sensitive to moisture and one or all polymeric layers 1, 100, 13, 11 and 12, 14, 10 based on a polyolefin are bonded to the respective surfaces of the intermediate layer so as to mutually have continuity and the layer assemblies 1, 21, 100, 13, 11, 21 positioned on the inner surface of the barrier-effect intermediate layer have a total thickness included within a range of 40-150μm so as to well hold the aroma or flavor of a substance contained or capable of being contained. |
