随着国民经济的发展,外贸出口和旅游事业的需要,人民生活水平的提高,食品卫生法的贯彻,这些都对包装行业提出了更新、更高的要求。为适应新形势,满足新要求,首先应发展包装机械的基础件,这样会缩短设计新型包装机的周期,加快产品更新换代的步伐。 With the development of the national economy, the needs of export and tourism, the improvement of people’s living standards, and the implementation of the Food Sanitation Law, all have put forward newer and higher requirements on the packaging industry. In order to meet the new situation and meet the new requirements, we should first develop the basic components of the packaging machinery, which will shorten the cycle of designing new packaging machines and accelerate the pace of product replacement.
