Abstract

L'invention porte sur un film adhésif et un procédé d'obturation d'ouvertures dans un substrat thermoplastique rigide tel qu'une fixation de tableau de bord de véhicule. Ledit film comporte une couche adhésive adhérant au substrat, et une couche de base thermodéformable. Dans l'une des variantes préférées, le film adhésif est thermoscellé autour des ouvertures du substrat à l'aide d'un procédé de thermoformage sous vide empêchant la mousse de polymère de s'échapper par les ouvertures pendant la fabrication du tableau de bord.
