（一）Packaging machinery industry development background
The packaging machinery industry has integrated technologies from various fields, including mechanical processing, electrical control, information system control, industrial robotics, image sensing technology, and microelectronics. By combining the production processes of downstream industries, it has achieved automation in a series of packaging operations such as forming, filling, sealing, labeling, coding, strapping, palletizing, and winding. Packaging machinery has become one of the key factors for companies to improve production efficiency, reduce labor intensity, improve working conditions, save labor costs, optimize production processes, and achieve mass production.
Since the 1960s, the global packaging machinery industry has experienced continuous development, fueled by the constant emergence of new packaging materials, techniques, and technologies. Alongside these innovations, the packaging needs of downstream industries have evolved, driving the demand for more advanced and efficient packaging equipment. As a result, packaging machinery has become a vital component in a variety of industries, including food, beverage, pharmaceuticals, chemicals, electronics, and logistics. In particular, the food and beverage industry has seen tremendous growth, with an increasing demand for high-quality packaging that can preserve product freshness, prevent contamination, and provide consumer convenience.
In the early stages of the packaging machinery industry, manual and semi-automatic traditional packaging equipment dominated, with low automation levels and poor adaptability. Market promotion was severely limited. With the rapid development of the national economy and the increasing demand for production automation across industries, the packaging machinery industry has developed rapidly. Packaging equipment has been widely applied in sectors such as food, beverages, pharmaceuticals, chemicals, mechanical manufacturing, and warehousing logistics. In recent years, influenced by factors such as intensified market competition in downstream industries, trends toward large-scale and intensive production, and rising labor costs, packaging equipment has played an increasingly important role in production and logistics. Highly automated, efficient, intelligent, and energy-saving packaging equipment has gradually gained favor in downstream industries. Traditional packaging equipment has gradually been integrated with fieldbus technology, drive control technology, motion control technology, automatic identification technology, and safety detection technology, leading to the emergence of modern intelligent packaging equipment.
