ール部材に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention contains a foaming agent to reduce the adhesive strength by heat treatment, and enables peeling without damaging the paper case or the like, enabling reuse of the paper case or the like. The present invention relates to a sealed member.

材の製造に多工程を要する難点があった。However, there is a problem that the adhesive strength is so great that it is damaged when peeled from the paper case, and the paper case cannot be reused. Further, it is difficult to directly apply the pressure-sensitive adhesive to the porous seal substrate, and the double-sided pressure-sensitive adhesive tape is laminated with the porous seal substrate. However, there is a problem in that the production of the seal member requires many steps.

【発明が解決しようとする課題】本発明は、紙製ケース
等よりそれを損傷させずに剥離できてケースを再使用で
きるシール部材を得ることを課題とする。SUMMARY OF THE INVENTION It is an object of the present invention to obtain a seal member that can be peeled off from a paper case or the like without damaging it and the case can be reused.

を特徴とするシール部材を提供するものである。The present invention is characterized in that an adhesive strength-reducing adhesive layer containing a foaming agent is provided on at least one side of a porous seal substrate, if necessary with a film-like intermediate layer interposed therebetween. A seal member is provided.

れを損傷させることがなく再使用が可能である。By the treatment for reducing the adhesive force by heating the adhesive force reducing type adhesive layer, the foaming agent contained therein expands or foams, whereby the adhesive force decreases or disappears. As a result, it can be peeled off easily from the adherend such as a case, and even in the case of a paper case, it can be reused without damaging it.
