Abstract

On vise à proposer un film de polyester thermorétractable qui rétrécit fortement dans le sens machine, qui est le sens de retrait principal, présente une résistance mécanique élevée dans le sens de la largeur, qui est perpendiculaire au sens de retrait principal, et présente un fini de film rétréci satisfaisant, une ténacité satisfaisante et une solidité satisfaisante après enveloppement et thermorétraction subséquente. À cet effet, le film de polyester thermorétractable a un sens principal de retrait qui est le sens machine. Le film a été ajusté de telle sorte que les valeurs des propriétés suivantes se situent à l'intérieur de plages respectives données : le degré de thermorétraction par l'eau chaude dans le sens machine après une immersion de 10 secondes dans de l'eau à 90°C ; le degré de thermorétraction par l'eau chaude dans le sens de la largeur après une immersion de 10 secondes dans de l'eau à 90°C ; une contrainte de retrait dans le sens machine dans un traitement à 90°C pendant 10 secondes ; un module d'Young dans le sens machine à la rupture ; et le degré de retrait naturel.
