摘要： A lid which is to be heat-sealed on a container, including a laminated sheet composed of a base layer, an adhesive layer, a metallic layer, and a heat-sealable resin layer, in which the base layer includes a single layer of a stretched resin film having many microvoids or a laminate containing at least the stretched resin film, the lid having an indication of the direction of stripping, including a lug provided at the periphery thereof or a print thereon, in such a manner that the indicated direction of stripping should be set within a range of .+-.45.degree. with respect to the direction of greatest thermal expansion coefficient of the base layer when heated from 30.degree. C. up to 80.degree. C. at a rate of temperature rise of 10.degree. C./min for 5 minutes. When hot water is poured into a container with the lid partly stripped, the lid is heated by the steam to close the container without assistance.
