Abstract
La présente invention a trait à une bande de composite pour les couvercles de contenants thermoplastiques à ouverture pelable du type doté d'une pellicule externe d'aluminium ou de matériau équivalent, d'une pellicule interne thermoplastique adéquate pour adhérer au rebord du contenant par thermoscellage, et d'une couche agglomérante intermédiaire disposée entre les pellicules externe et interne. La pellicule interne a une ligne de refoulage à l'endroit de chaque couvercle de façon à former une ouverture lorsque la couche est pelée. La couche intermédiaire n'est pas uniforme, y compris les premières zones constituées par une première substance thermosensible ayant une haute affinité avec la pellicule thermoplastique sous l'effet de la chaleur. La majeure partie de la couche intermédiaire est constituée d'une substance thermorésistante qui a une affinité moyenne avec la pellicule thermoplastique; elle peut donc être pelée.
