batches of cans with 6 tinplate variables of varying tincoating weight and surface coatings, were used to pack vanaspatl These cans were evaluated by storing at ambient temperature (25-30°C), 37°C and conducting periodical cutout examination by chemical analysis and organoleptic evaluation. E-25 (with lithograph on external surface), E-50 (both sides plain), E-20 and E-25 tinplate cans (with tinplate or black plate lacquered components) coated with lacquer on the internal surface and lacquer or lithography on the external surface, were found suitable for packing vanaspatl However, storage for 6 months or longer at high humidity, the external rusting would be more, especially at the seam ends. E-10 cans, even with lacquer coating on both the internal and external surfaces, were not suitable for long storage.
