Title (EN) LAMINATED CAN END STOCK WITH ELEVATED TEMPERATURE ANNEALING
(FR) MATIÈRE PREMIÈRE D'EXTRÉMITÉ DE CANETTE STRATIFIÉE AVEC RECUIT À TEMPÉRATURE ÉLEVÉE
Abstract:
(EN) Improved aluminum can end stock (CES) is disclosed. The CES includes a laminated, amorphous polymer coating exhibiting low feathering, low blushing, and high performance in an acetic acid test. The laminated metal strip (102) can include the laminated polymer coating (124) on an interior-facing side and a lacquered coating on an exterior-facing side. Tile CES is formed by performing an annealing process on the laminated metal strip (102), wherein the metal strip is raised to an annealing temperature above the melting point of the polymer for a sufficient duration to render the polymer amorphous. In some cases, the polymer film laminated to the metal strip is a polyethylene teraphthalate (PET) film.
(FR) L'invention porte sur une matière première améliorée d'extrémité de canette (CES) en aluminium. La CES comprend un revêtement polymère amorphe stratifié présentant un faible amincissement des bords, une faible opalescence et des performances élevées dans un test à l'acide acétique. La bande métallique stratifiée (102) peut comprendre le revêtement polymère stratifié (124) sur un côté tourné vers l'intérieur et un revêtement laqué sur un côté tourné vers l'extérieur. La CES est formée en exécutant un processus de recuit sur la bande métallique stratifiée (102), la bande métallique étant amenée à une température de recuit supérieure au point de fusion du polymère pendant une durée suffisante pour rendre le polymère amorphe. Dans certains cas, le film polymère stratifié sur la bande métallique est un film de polyéthylène téréphtalate (PET).
