A laminated sheet for a lid of a container for instant food cooked with hot water, comprising a metallic foil and a synthetic paper affixed to the metallic foil is disclosed. Self sealing of the container is achieved after the lid is partly peeled and hot water is poured into the container.

Laminated sheet for a lid of a container for instant food cooked with

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.
