In recent years, the packaging machinery industry in our country has achieved rapid development, but there have also been some phenomena of low-level repeated construction. According to relevant data, compared with industrially developed countries, our food and packaging machinery products lack 25% ~ 30% in variety, and the technology level lags behind by 15 ~ 25 years. Experts believe that the low-level repeated construction of packaging machinery has constituted an obstacle to the upgrading, replacement and innovation of industry products, and ways should be found to solve this problem. But it can only be achieved through market regulation and strengthening the supervision of its downstream industry - the food industry to realize natural elimination.
