Abstract

La présente invention concerne une feuille métallique revêtue de résines polyester. Ces résines polyester présentent une viscosité intrinsèque comprise entre 0,6 et 1,4 et ne sont pas orientées. La surface de la feuille métallique correspondant à la surface interne d'une canette à fabriquer avec la feuille métallique est revêtue de deux couches de résine. Une résine polyester de couche supérieure présente une température de fusion supérieure à celle d'une résine de couche inférieure. La surface de la feuille métallique correspondant à la surface externe de la canette est revêtue de trois couches de résine. Les résines polyester des couches supérieure et centrale présentent une température de fusion supérieure à celle d'une résine de couche inférieure, les résines des couches supérieure et inférieure présentant une teneur en pigment blanc inférieure à celle de la résine de la couche centrale. En outre, cette invention concerne une canette composée de cette feuille métallique. La feuille métallique revêtue de résines polyester ne subit pas de craquelure ou de cassure même si est elle soumise à un façonnage intense pour la former, comme par exemple l'emboutissage profond en paroi mince, et présente par ailleurs d'excellentes caractéristiques en terme d'aptitude au façonnage et de résistance à la corrosion. De plus, la canette composée de cette feuille métallique préserve très bien les caractéristiques aromatiques de son contenu.
