Title
(EN) A WATER-SOLUBLE CO-POLYESTER POLYMER AND A PROCESS OF SYNTHESIS THEREOF
(FR) POLYMÈRE DE CO-POLYESTER SOLUBLE DANS L'EAU ET SON PROCÉDÉ DE SYNTHÈSE
Abstract
(EN)
The present invention relates to a water-soluble co-polyester polymer. The polymer of the present invention is used for inline coating of BOPET film manufacturing, coating of BOPET film used as primer for vacuum metallization and surface coating of Aluminum sheets. The polymer of the present invention provides wide range of printability performances and high metal to film bond strength with minimum gain in weight. The disclosed polymer also provides Tape Test resistant printing and retort resistant layered/composite film.

La présente invention concerne un polymère de co-polyester soluble dans l'eau. Le polymère selon la présente invention est utilisé pour le revêtement en ligne lors de la fabrication de film BOPET, le revêtement de film BOPET utilisé comme amorce pour la métallisation sous vide et le revêtement de surface de feuilles d'aluminium. Le polymère selon la présente invention offre une large gamme de performances en terme d'aptitude à l’impression et une grande résistance de liaison métal-film avec un gain de poids minimal. Le polymère selon l'invention permet d'obtenir également une impression résistante à l'essai du ruban et un film stratifié/composite résistant à la stérilisation en autoclave.
