Document Type and Number:
WIPO Patent Application WO/2023/243450
Kind Code:
A1
Abstract:
A seal material 1a has a first surface 11 and a second surface 12. The second surface 12 faces the opposite direction of the direction faced by the first surface 11. The seal material 1a satisfies the conditions F1≥F2, T>F2, F1≥0.3 N/20 mm, and F2≥0.3 N/20 mm. F1 is the 90° peeling adhesive force [N/20 mm] measured by peeling the first surface 11 in accordance with JIS Z 0237:2022. F2 is the 90° peeling adhesive force [N/20 mm] measured by peeling the second surface 12 in accordance with JIS Z 0237:2022. T is the tear strength [N/20 mm] measured in accordance with JIS K 6252-1:2015 using an unnicked angle test piece produced from a portion of the seal material 1a that is away from the first surface 12 and the second surface 12.
