Applications

 

By far the largest application of tinplate is in packaging and it is ideally suited for this purpose, by virtue of it being non-toxic, light in weight, strong, corrosion resistant and easily formed, soldered and welded; it also provides an excellent printing surface. The tin coating has a low melting point, possesses lubricant qualities and imparts a good appearance. Cans made from tinplate are easy to handle, dispose and store. Tinplate is primarily used for packaging foodstuffs and beverages, but it is also used in containers for oils, grease, paints, powdered, polishes, waxes, chemicals and many other products. Aerosol containers and caps and closures are also made from tinplate.
