According to the function can be divided into single-function packaging machine and multi-functional packaging machine; according to the purpose can be divided into within the packaging machine and packaging machine; according to the packaging varieties can be divided into special packaging machines and general packaging machine; by automation level is divided into semi-automatic machine And automatic machines. The following brief description of several packaging related equipment.
The carton is a machine for the sale of the product, which loads the metered material into the box and closes or seals the opening of the box. The packing machine is used to complete the transport package, which will pack the finished product in a certain way and quantitative loading into the box, and the opening part of the box closed or sealed. Carton and packing machine are container forming (or open the container), measurement, loading, sealing and other functions.
Forming - filling - sealing packaging machine is a multi-functional packaging machine. Material into the top of the packaging machine, the measurement part of the number of products will be set in turn into the material channel. When the wrapping material is passed through the outer wall of the material passage, the former is wound into a cylindrical shape by the former, and the longitudinal seal is welded to the longitudinal seam. The transverse seal completes the top of the bag and the bottom of the next bag, making it two welds. As the cutting channel is wrapped by the packaging bag, the bottom seal welding can be directly to the bag after the material, followed by a station to complete the top seal, and cut with a cutter to complete the packaging process.
The roll packaging material has a single layer and a composite. Monolayer such as moisture-proof cellophane, polyethylene, polypropylene, high-density polyethylene, composite, such as stretched polypropylene / polyethylene, polyethylene / cellophane / aluminum foil. There are also materials that can be heat-sealed. Packaging sealing type pillow type sealing, trilateral sealing and four sides sealing and so on.
