The packaging process includes main steps such as filling, wrapping, and sealing, as well as related pre- and post-processes such as cleaning, feeding, stacking, and unpacking. Packaging also includes steps such as measuring or printing dates on the packages. Using packaging machinery can improve productivity, reduce labor intensity, meet the needs of large-scale production, and satisfy hygiene requirements.
A sealing packaging machine is a multi-functional packaging machine.
Roll packaging materials are available in single-layer and composite forms. Single-layer materials include moisture-proof cellophane, polyethylene, polypropylene, and high-density polyethylene; composite materials include stretched polypropylene/polyethylene and polyethylene/cellophane/aluminum foil. There are also heat-sealable materials. Packaging sealing methods include pillow seals, three-side seals, and four-side seals. Cartoning machines are used for product sales packaging.
A cartoning machine is a machine used for product sales packaging. It fills a measured quantity of material into a box and closes or seals the opening. A case packing machine is used for transport packaging. It fills packaged products into boxes in a specific arrangement and quantity, and closes or seals the opening. Both cartoning and case packing machines have functions such as container forming (or opening), metering, filling, and sealing.
The processes for bottle filling lines for various beverages are basically similar. However, due to the different nature of the beverages, the filling and capping machines used are also different. For example, in addition to selecting a suitable filling and capping machine, a sterilization machine is added to a beer filling line. The capping machine is selected according to the type of cap used (crown cap, screw cap, cork cap, etc.).
