SHEET-LIKE LID BODY

摘要

PROBLEM TO BE SOLVED: To provide a sheet-like lid body with a function realizing the same effect as a dead hold suitability which has been accomplished by a metal layer such as an aluminum foil without using the metal layer such as the aluminum foil in a layer constitution. SOLUTION: In the sheet-like lid body which tightly seals an opening part of a closed-end container main body with the opening part on its top face by releasably heat-adhesion and contains no metal layer in the layer constitution and is provided with a tab projection on the peripheral edge, the sheet-like lid body is characterized by providing the first pressure-sensitive adhesive coated part at a neighboring position of the tab projection on the surface of the outer layer of the sheet-like lid body and the second pressure-sensitive adhesive coated part at a more distant position than the first pressure-sensitive adhesive coated part from the tab projection and the first and second pressure-sensitive adhesive coated parts being formed of self-adhesive pressure-sensitive adhesive compositions.
