摘要：
A paper seal comprising a stretched thermoplastic resin film that comprises (a) a surface layer, (b) a substrate layer, and (c) a water-based adhesive-receiving layer having a water absorption level of from 2 to 25 ml/m2, wherein the stretched thermoplastic resin film has a porosity of from 20 to 50% and a 120°-opening time by bending repulsion of from 20 to 70 seconds. The paper seal can be stuck in a flat state without being curled by the environmental influence during labeling or by the influence of seasonal variation, and can be peeled off completely.
