<P>PROBLEM TO BE SOLVED: To provide a lid material as a laminate having a constitution using no aluminum foil which is free from any environmental problem when disposing a used container formed thereof, and allowed in detection by a metal detector as a countermeasure for avoiding the mixture of foreign matters in a product, and has a sufficient dead fold property and re-sealing performance, and a container using the lid material. <P>SOLUTION: In the lid material, an upper sheet composed of a plastic film and a paper base material and a lower sheet having a thermoplastic film, a lower base material and a sealant layer are layered. The lid material has an unsealing tab for unsealing at an outer circumferential edge and a peeling tab for peeling a part of the lid material, a peeling layer demarcated into a peeling portion and a non-peeling portion between the upper sheet and the lower sheet toward an end facing the peeling tab, and two rows of cutting lines having cuts demarcating the upper sheet into a peeling area corresponding to the peeling layer and an adhesive area other than the peeling area on the upper sheet. The lid material has a substantially U-shaped peel starting piece in which an end of a cut line formed along an inner periphery of the peeling tab is continuous to the cutting line. <P>COPYRIGHT: (C)2010,JPO&INPIT |
