<P>PROBLEM TO BE SOLVED: To provide a cover material of a container with hot water draining function, which has favorable productivity, satisfies both of a discharge part peelability and an adhesive strength on a discharge hole area above hot water, has a wide degree of freedom of an outer circumference of a discharge part and shape of a discharge hole, has no deteriorated peelability even in long storage, and exhibits the excellent practical effect. <P>SOLUTION: The cover material is configured such that an upper sheet can be peeled from a lower sheet on the whole surface by interfacial peeling between the upper sheet and the lower sheet, wherein the interface of one side sheet is an interface made of a plastic material, the interface of the other side sheet is an interface made of a polyolefin-based adhesive resin, the plastic material is a biaxially stretched film and a coating layer for improving peel strength laminated on the interface with the adhesive resin contains a nitrocellulose resin, the component ratio of which is 10 to 70%. <P>COPYRIGHT: (C)2013,JPO&INPIT |
