La bande adhésive (12) comprend une couche adhésive de SIS (33) qui forme la surface adhésive (32), et une partie séparatrice (34) qui est partiellement prévue sur la couche adhésive (33) aux fins d’empêcher l’adhérence de la surface adhésive (32) sur l’autre surface de la base (20). La partie séparatrice (34) est formée à partir d’un élastomère qui utilise un polymère non acrylique différent de celui de la couche adhésive (33) comme polymère de base, et qui présente un module de conservation dans la plage allant de 1,6 × 105 Pa à 4,2 × 105 Pa à 20 °C tel que mesuré à une fréquence d’1 Hz.
