Abstract
Il procedimento per produrre una lamiera metallica laminata con una pellicola di poliestere, per la produzione di lattine aventi un'eccellente resistenza alla modificazione lattiginosa conseguente ad un trattamento in forno dopo l'introduzione di alimenti e bevande, consiste nel controllare in un campo ottimale il rapporto relativo di densità ed il grado residuo di orientamento biassiale di una pellicola laminata di resina poliestere orientata biassialmente contenente circa dal 10% al 60% in peso di polibutilene tereftalato e circa dal 90% al 40% di polietilene tereftalato, e presentante, nel laminato prima del trattamento in forno, una temperatura di transizione vetrosa da circa 40°C a circa 70°C, dopo la laminazione su una od entrambe le facce di una lamiera metallica rivestita con un singolo strato di idrossido di cromo oppure con un doppio strato costituito da uno strato inferiore di cromo metallico e da uno strato superiore di idrossido di cromo.
