The rotary premade pouch packaging machine integrates various functions such as metering, filling, sealing, coding, labeling, and vacuum/modified atmosphere packaging. The equipment can accommodate prefabricated bags made of various materials, such as plastic composite bags, aluminum foil bags, paper bags, stand-up pouches, and zipper bags.

This machine integrates metering and filling functions, enabling precise metering of materials according to preset parameters and filling them into prefabricated bags. Depending on the form of the material, it can be subdivided into granular metering and filling machines, powder metering and filling machines, liquid metering and filling machines, etc. For example, granular metering and filling machines use vibrating feeding or screw feeding methods, suitable for granular materials such as nuts, candies, and feed; powder metering and filling machines are equipped with spiral metering or vacuum feeding systems to solve the problem of dust flying, suitable for powdered materials such as milk powder, flour, and coffee powder; liquid metering and filling machines use piston-type or flowmeter-type metering to precisely control the liquid volume, used for filling liquid products such as soy sauce, cooking oil, and shampoo. Designed for materials with various forms of mixing, such as solid-liquid mixing and solid-solid mixing, such as pre-prepared meals with soup, mixed snacks of nuts and dried fruits, and traditional Chinese medicine formula granules. The equipment is equipped with a multi-station metering and filling system, which precisely meters materials of different forms and fills them into prefabricated bags in order. Some models also have a mixing function to ensure uniform distribution of mixed materials and meet the packaging needs of complex materials.
