Adhesive material

Abstract

This article is an adhesive material used, for example, to protect the skin. As shown in [Reference enlarged cross-sectional view A-A showing the names of each part], this adhesive material is composed of a printed protective layer, a micro-adhesive layer, a base material layer, an adhesive layer, and a release paper. One surface of the base material layer is attached to the release paper via the adhesive layer. One surface of the printed protective layer is attached to the base material layer via the micro-adhesive layer. The printed protective layer, the micro-adhesive layer, the base material layer, the adhesive layer, and the release paper each have a small-diameter arc portion of a small-diameter arc shape and a large-diameter arc portion of a large-diameter arc shape, sandwiching their constricted portions. The base material layer, the adhesive layer, and the release paper are each divided into two by providing a slit in their constricted portions. The printed protective layer and the micro-adhesive layer are each divided into two by providing a wavy cut in their large-diameter arc portions when viewed from the front. The large-diameter arc portions of the printed protective layer and the micro-adhesive layer each have a diameter of about two wavelengths of the cut. The user of this article, as shown in [Reference enlarged cross-sectional view 1 showing the use state], grips the entire small-diameter arc portion and peels it off from the large-diameter arc portion of the release paper, and after sticking the large-diameter arc portion of the exposed adhesive layer to an adherend such as the skin, as shown in [Reference enlarged cross-sectional view 2 showing the use state], the printed protective layer and the micro-adhesive layer that are divided into two are peeled off by pushing up their cut sides respectively, leaving the large-diameter arc portions of the base material layer and the adhesive layer on the adherend.
