A filling machine is a machine that fills packaging materials into a packaging container according to a predetermined amount. The materials generally filled are solid substances such as powders and granules, which are not fluid. There are usually three common metering methods for material filling, namely volumetric, weighing, and counting . Different types can be subdivided according to the different ways of achieving metering. Different packaging materials require different filling methods, and different filling methods require different filling machines to achieve. The common bag filling machines on the market can not only complete the filling of materials, but also complete the processes such as bag forming and sealing.

A filling machine is a machine that fills materials into packaging containers according to quantity. Such materials are generally in liquid or semi-liquid state and have a certain fluidity. Filling machines are divided into normal pressure filling machines, negative pressure filling machines, isobaric filling machines and pressure filling machines according to the filling air pressure. According to the transportation method of the packaging container, there are linear filling machines and rotary filling machines.

Sealing machines seal packaging containers that contain materials. In the specific packaging industry, different packaging containers and different packaging methods require different sealing machines. Thermostatic sealing machines are usually used for the packaging of plastic bottle sealing films and plastic bags. Capping sealing machines are often used for functional plastic cap bottles in packaging form. Crimping sealing machines are used for canned food packaging.

Wrapping machine is a machine that wraps part or all of the product surface with flexible materials . There are many types of wrapping machines according to the different packaging forms . Common packaging methods include heat shrink, winding, stretching, on-site foaming, etc.

In actual packaging equipment, more and more machines can realize multiple packaging functions, rather than simply realizing a single packaging process. For example, the bagging machine mentioned above seals the plastic film after completing the filling of the material. There is also a vacuum packaging machine as shown in the figure below, which completes the filling, vacuuming and sealing of rice in the bag. With the development of industry, there are more and more personalized demands for the packaging industry, and the same equipment will meet multiple packaging functions.

A labeling machine is a machine that uses adhesives or other methods to display labels on packaging or products. Different labeling machines are selected according to different label forms and label materials. Common labeling machines include labeling machines, sleeve labeling machines, shrink labeling machines, self-adhesive labeling machines, etc.

A cleaning machine is a machine that cleans packaging containers, packaging materials, packaging objects, and packaging items to achieve the expected cleanliness requirements. Depending on the cleaning solvent, cleaning machines can be divided into air washing and water washing .

A dryer is a machine that removes moisture from packaging containers, packaging materials, packaging aids and packaging , and performs the desired drying.

A sterilizer is a machine that kills harmful microorganisms on packaging materials, packaging containers, packaging materials, packaging aids and packaging items to reduce them to an allowable range.

A strapping machine is a machine that straps products or packages with strapping tape or rope, tightens the strapping tape and fuses the two ends of the strapping tape through thermal effects or connects them with materials such as buckles.

A container loader is a machine that integrates or disassembles packaging units to form suitable handling units. It is usually used for secondary packaging for the purpose of storage and transportation.

Auxiliary packaging machines refer to machines that perform non-primary packaging processes on packaging materials, packaging containers, packaging aids and packaging, such as capping machines .
