摘要
对DR材三片罐的制造难点进行了简单介绍。同时,从DR材性能,薄材的印涂实现,焊接、薄材成型、封口技术的创新,精确液氮加注及高温反压杀菌技术几个方面,分析了DR材三片罐制造与应用中的技术创新。这些技术的创新使得DR材三片罐在食品饮料金属包装方面的应用达到了节约资源和能源的目的,体现了食品饮料金属包装的发展方向。最后,探讨了DR材三片罐批量化应用中存在的问题并提出相应建议。
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.
