Title (EN) MANUFACTURING PROCESS FOR POLYESTER FILM EXHIBITING LOW THERMAL SHRINKAGE
(FR) PROCÉDÉ DE FABRICATION D'UNE PELLICULE DE POLYESTER PRÉSENTANT UN FAIBLE RÉTRÉCISSEMENT THERMIQUE
Abstract: front page image
(EN)A process in which a wound roll of biaxially oriented polyester film having a glass transition temperature (Tg (°C)) is annealed at a temperature Ta (°C) above Tg where Tg < Ta ≤ Tg + 100 (°C) for a time t after thermal equilibrium where 1 hour ≤ t ≤ 72 hours and cooled, for the purpose of improving the shrinkage of said polyester film.
(FR)L'invention concerne un procédé selon lequel un rouleau enroulé de pellicule de polyester à orientation biaxiale, présentant une température de transition vitreuse (Tg (°C)), est recuit à une température Ta (°C) supérieure à Tg (Tg < Ta ≤ Tg + 100 (°C)) sur une durée t après équilibre thermique (1 h ≤ t ≤ 72 h), et refroidi de manière à améliorer le rétrécissement de ladite pellicule de polyester.
