It is a multifunctional packaging machine. After the material enters the top of the packaging machine, the metering part will send the determined quantity of products into the material channel in turn. When the roll packaging material passes through the outer wall of the material channel, it is wound into a cylindrical shape by the former, and the longitudinal sealer seals the longitudinal seam firmly. The horizontal sealer completes the top seal of the packaging bag and the bottom seal of the next bag, becoming two welds. Because the discharge channel is wrapped by the packaging bag, the bottom seal can be directly discharged into the bag after welding, and then a station is moved to complete the top seal and cut with a cutter to complete the packaging process.
Roll packaging materials are available in single and composite layers. Single layer such as moisture-proof cellophane, polyethylene, polypropylene, high-density polyethylene, and composite such as stretch polypropylene / polyethylene, polyethylene / cellophane / aluminum foil. There are also heat-sealable materials. Packaging sealing types include pillow sealing, three-side sealing and four-side sealing.
