With the beginning of the industrial revolution, mechanical production gradually replaced the traditional manual production mode. In recent decades, people are more and more aware of the packaging of products, packaging industry has also been a very rapid development, such as bag packaging machine it is a large part of the replacement of manual packaging for large enterprises, small and medium-sized enterprises to realize the packaging automation, the operator as long as a one-time hundreds of bags on the equipment to take the bag department, the equipment mechanical grasp will automatically take the bag, print the date, open the bag, to the measuring device Signal measurement and drop, sealing, output. Customers can also be based on product packaging needs to set up the door open emergency stop, automatic card, abnormal discharge and other details of the function, packaging the whole process without manual work, effectively improve the production efficiency for the enterprise, save labor costs and management costs, significantly reduce costs.
Before the Industrial Revolution, the packaging industry predominantly relied on manual labor. People used simple tools to make bags and fill them with goods, such as folding paper into bags and manually filling them with grains or candies. This primitive packaging method was inefficient, and the quality of packaging entirely depended on workers' experience. At the end of the 18th century, with the advent of the First Industrial Revolution, mechanical principles began to be applied in the packaging field. In 1807, French inventor Nicolas Appert invented the canning method for food preservation, indirectly promoting the early exploration of packaging machinery. In the mid-19th century, simple mechanical bag presses emerged, using the principle of levers to form bags preliminarily. However, these devices still required substantial human intervention, and a complete packaging process had not yet been established.
In the early 20th century, the breakthroughs in power technology brought about by the Second Industrial Revolution laid the foundation for the development of packaging machinery. In 1912, the first semi-automatic form-fill-seal (FFS) machine appeared in the United States. This device could automatically form and seal bags, but the filling process still required manual operation. In the 1930s, with the maturation of electric motor and gear transmission technologies, the prototype of the fully automatic bag packaging machine emerged. For example, the horizontal pillow-type packaging machine developed by Germany in 1935 achieved continuous operations of film bag-making, material filling, sealing, and cutting for the first time, mainly applied to the packaging of foods like candies and biscuits. The equipment of this period used mechanical cam control. Although the degree of automation was limited, it established the basic functional modules of bag packaging machines—bag-making, filling, sealing, and cutting.
After the 1960s, electronic technology, pneumatic-hydraulic technology, and sensor technology brought by the Third Scientific and Technological Revolution were deeply integrated into the field of packaging machinery. In 1965, Japan introduced the first vertical bag packaging machine based on pneumatic control, which used photoelectric sensors to position packaging materials, significantly improving sealing accuracy. In the 1970s, the application of Programmable Logic Controllers (PLCs) initiated the digital control era of bag packaging machines. Equipment could achieve quick switching of different packaging specifications through programming. During the same period, breakthroughs were made in sealing technology. Various sealing methods, such as heat sealing, cold sealing, and ultrasonic sealing, met the packaging requirements of different materials (plastic films, composite films, aluminum foils). For instance, the three-side seal and four-side seal bag packaging machines widely used in the 1980s could adapt to the packaging of various products, including pharmaceuticals and daily necessities. Additionally, advancements in metering technology (such as volumetric metering, weighing metering, and screw metering) enabled packaging machines to accurately control material filling, reducing the error rate from the early 5% to 1%-2%.
Entering the 21st century, with the development of Industry 4.0 and Internet of Things (IoT) technology, bag packaging machines have witnessed intelligent transformations. Servo motors replaced traditional motors, achieving high-precision and low-noise motion control, and the packaging speed increased from dozens of bags per minute to hundreds (for example, high-speed vertical packaging machines can reach 300 bags per minute). The application of machine vision systems has solved the problem of defect detection during the packaging process, enabling automatic identification of sealing flaws, label misalignments, and other issues. After 2015, packaging machines equipped with artificial intelligence algorithms can optimize packaging parameters by learning from historical data, adapting to the flexible production needs of multi-variety and small-batch production. For example, food enterprises can quickly switch between packaging specifications for potato chips, nuts, and candies on the same device, reducing the changeover time from 30 minutes for traditional equipment to within 5 minutes.
While innovating technologically, the concept of environmental protection has driven the green transformation of packaging machinery. The application of degradable materials (such as PLA biodegradable films) has prompted the research and development of equipment to adapt to the characteristics of new materials. Low-energy-consumption servo systems and energy-saving heating devices have reduced energy consumption during the production process. Moreover, the diversification of packaging forms has given rise to the development of special bag packaging machines, such as stand-up pouch packaging machines, zipper bag packaging machines, and special-shaped bag packaging machines, meeting consumers' demands for convenience and aesthetics. In the pharmaceutical field, sterile bag packaging machines achieve aseptic filling of drugs through isolation technology, complying with GMP standards. In the chemical industry, bulk bag packaging machines solve the problem of automated packaging of large quantities of granular materials.
Fully automatic bag packaging machine, horizontal bag packaging machine, horizontal double out of the bag packaging machine, shaped bag packaging machine, the use of advanced PLC plus POD (touch screen) electrical control system, man-machine interface is friendly, easy to operate, and is equipped with a detection device, you can detect the machine in the absence of packages or bags do not open the case so that the filling device does not fill the heat sealing device does not seal, thus avoiding the waste of packaging materials and raw materials. Avoid wasting package materials and raw materials. Equipment using frequency conversion speed control device, according to actual needs in the production of a certain range of arbitrary adjustment, can quickly change the specifications of the bag, automatic bag packaging machine, horizontal bag packaging machine, horizontal double out of the bag packaging machine, high-speed bag packaging machine, bag packaging machine, bag packaging machine, the width of the shaped may be easily and quickly adjusted through the adjusting handle in adjusting the specifications of each mechanical claw spacing can be completed by only one bolt. 10 pairs of mechanical claw specification conversion, easy to operate. Normal service life is more than 10 years.
