包装机是一台包装机，可将精确数量的包装加载到各种容器中。

4. Molding - filling - sealing packaging machine it is a multi-functional packaging machine (figure 1). After the material enters the top of the packaging machine, the measurement part will send the specified quantity of products into the material channel in turn. When the packaging material of the reel passes through the outer wall of the material channel, it is wound into a barrel by the former. The transverse seal completes the top seal of the packing bag and the bottom seal of the next bag, becoming two welds. As the feeding channel is wrapped by the packaging bag, the bottom sealing can be directly fed into the bag after welding, and then move a station to complete the top sealing and cutting with the cutting knife to complete the packaging process.
