LAMINATE SHEET |
摘要 |
Provided is a laminate sheet with which degradation of the appearance after its application can be highly prevented while maintaining good adhesive properties. The laminate sheet provided by this invention is a long laminate sheet having an adhesive surface. The laminate sheet comprises a PSA layer forming the adhesive surface and an air-impermeable substrate sheet supporting the PSA layer. The substrate sheet surface is partially provided with the PSA layer, whereby the substrate sheet surface has a PSA-bearing area and a PSA-free area. The PSA-free area includes at least a strip-shaped area. The strip-shaped area runs at angles intersecting the width-direction edges of the laminate sheet. |

1. A long piece of laminate sheet having an adhesive surface, the laminate sheet comprising:
a pressure-sensitive adhesive layer forming the adhesive surface; and an air-impermeable substrate sheet supporting the pressure-sensitive adhesive layer, wherein the substrate sheet has a surface partially provided with the pressure-sensitive adhesive layer, whereby the surface of the substrate sheet has a pressure-sensitive adhesive-bearing area and a pressure-sensitive adhesive-free area, the pressure-sensitive adhesive-free area includes at least a strip-shaped area, and the strip-shaped area runs at angles that intersect width-direction edges of the laminate sheet. |
