Heat shrink packaging machines are widely used in various fields of national economy and people's livelihood. Due to the need to adapt to different working conditions, there are numerous varieties and quantities of shrink machines. The manufacturing industry of fully automatic plastic packaging machines is very large, with thousands of shrinking machine manufacturers spread across the country. Currently, China has become one of the countries with high global shrinking machine production and market demand. However, most of China's shrinking machine industry is small and medium-sized enterprises, with uneven quality and less than 10 companies with an annual output value exceeding 100 million yuan. Even compared with other machinery industries in China, there are shrinking machine enterprises that attach great importance to the development of new products in terms of equipment and technical level. It should be noted that although China's shrink machine industry still lags behind the international advanced level, it has surpassed the stage of simply copying and absorbing. Seeking further technological avenues for development should be based on analysis and reference.
