Nowadays, although the annual growth rate of China's packaging industry ranks first in the traditional industry, in order to integrate with the international market, it is necessary to accelerate the development of packaging technology and make it develop in an economic, efficient, and multifunctional direction. This is a good development opportunity for some enterprises. Chinese paper bag machine equipment manufacturing enterprises should seize this opportunity.
        The replacement method is to replace local parts, components or critical components and key technologies, so as to achieve the purpose of replacing a unit, so that the original packaging machinery equipment or production line production capacity, performance, efficiency, models and assembly methods, etc. Get updated. In this way, most parts and unit parts are reused, which not only increases the value of equipment, but also saves raw materials and a large amount of labor, and reduces costs.
        This development trend shows that packaging machinery, equipment, and production lines are increasingly moving towards a standardized, serialized, integrated, assembled, and online model. Civil and military high technology will also enter the entire packaging machinery and equipment field more and more widely. The fierce market competition will undoubtedly accelerate the pace of upgrading and technological transformation of packaging machinery and equipment in various industries.
        In today's world, the upgrading of packaging machinery and equipment and production lines has led Japan to lead the way, earning a lot of dollars in this field. Southeast Asia has also followed Japan's example and has unintentional performance in the manufacturing of packaging machinery and equipment and production lines. In the European Community, the pace of upgrading packaging machinery and equipment and production lines in Italy has come much faster than other member states.
        The comprehensive upgrading of packaging machinery and equipment is the general trend of the development of packaging machinery in China and the world. The main features of the upgrade are: a large number of modern and sophisticated technologies, electronics, microelectronics, edge technology, and fuzzy technology used in the civilian and military industries are transplanted to accelerate the further improvement of the reliability, safety, and security of packaging machinery and equipment, production lines, Unmanned level of automation.
        Packaging machinery and equipment, production line manufacturing groups, and multinational companies in many countries in the world are investing huge amounts of money and organizing professionals to carry out development and research, and strive to accelerate the mechatronics process of paper bag machine equipment. The key contents of its development research can be summarized as follows:
        1. Developed multi-functional models for packaging, filling, filling and packaging of various substrate bags, which can operate multi-functional packaging of substrates such as paper, plastic, aluminum foil, and composite materials.
        2. Develop energy-saving (water, electricity, oil, steam, etc.) models that save resources (raw materials, auxiliary materials, etc.) consumption indicators, and models that recycle waste materials.
        3． Developed a multi-shape packaging machine capable of multi-functional packaging of square, rectangular, circular, oval, triangular, pillow-shaped, strip-shaped, and odd-shaped packages.
        4． Developed a multi-base paper bag machine, a multi-functional machine that can process single-layer paper bags and plastic film bags, aluminum foil composite bags, and paper-plastic composite bags.
        5． Develop models with low energy consumption, high output power, good dynamic stability, low voice, and low pollution.

        6. Developed multi-material packaging machine (long paper bag machine, kraft paper bag machine), which can be used for liquid, semi-fluid, viscous, pulpy and solid particles, granules, powders, flakes, blocks, strips A multi-functional packaging machine for items such as shapes and odd shapes.
