The difficulty in manufacturing double reduced tin-plate can is briefly introduced while the technical developments in DR can including material performance, seal coat realization, welding, forming, the innovation in the sealing technology, accurate liquid nitrogen charging, high temperature back pressure sterilization are analyzed. All of these technical innovations in double cold reduced tinplate (referred as DR material) in food and beverage packaging could save resources and energy and reflect the development direction of food and beverage metal packaging. The problems and suggestions in mass production by using DR can are discussed as well.
