Traycans: Tinplate vs. Tin-Free Steel. Phase 1
Abstract
The purpose of this study was to develop an improved traycan which would provide a longer shelf life than the existing tin-free steel traycan. A storage study was initiated which included several variables such as storage temperature, product and can composition. Five can variables -- four tinplated steel variables with newly designed coating systems and a control (tin-free steel) variable -- were filled with six different products. The filled and processed traycans were stored at 40, 80 and 100 F. The traycans were inspected both internally and externally for aberrations after predetermined periods of storage. Test results showed that tinplate did not provide improved corrosion resistance over the existing tin-free steel traycan. This study recommends that the traycan composition be converted to 75/ 25 (0.375/0.125 lb/BB) -- based on follow-up discussions with Central States Can Co. -- differentially coated tinplate with an aluminum vinyl/epoxy phenolic double coating system, and that a sheet feed system be used in lieu of the current coil feed system.
