Packaging process includes filling, wrapping, sealing and other major processes, and the associated processes before and after, such as cleaning, stacking, and demolition  In addition, the package also includes a measurement or stamped on the package and other processes. Using mechanical packaging products can increase productivity, reduce labor intensity, adapted to mass production needs, and meet hygiene requirements.
There are a variety of packaging machinery classification methods. According to the functions can be divided into single-function and multifunction packaging machine packing machine; according to the purpose of use can be divided into inner and outer packaging machine machine; press pack varieties can be divided into specific and generic packaging machine packing machine; divided into semi-automatic machine according to the level of automation and fully automatic machines.
Forming - fill - seal packaging machine is a multi-functional packaging machine. The top material into the packaging machine, the part will be a good measurement of the number of products in turn fed into the material channel. Reel packaging material in the outer wall of the channel through the material when being wound into a cylindrical shape shaper, vertical sealing device to seal the longitudinal seam welding firm. Horizontal pouch packer completed and the next top closure bottom seal bag, becoming two welds. As the next feeding channel is wrapped bags, bottom seal can seal weld cutting directly to the bag, moves a complete top seal sealing station and cut with a cutter, complete the packaging process.
Reel packaging materials and composite monolayer. Moisture-proof layer such as cellophane, polyethylene, polypropylene, high density polyethylene, a composite such as tensile polypropylene / polyethylene, polyethylene / cellophane / aluminum foil. There are also heat-sealable materials. There pillow type packaging sealing sealing sealing edges trilateral sealing and so on. Cartoning machine for product sales packaging.
Cartoning machine is used for packaging machinery sales, it will go through a quantitative measurement of the material into the box and close the opening portion of the box or cementing. Packing machine for the completion of transport packaging, packaging products it by a certain arrangement and quantitative boxed and put the box closed or open part cementing. Cartoning machines and packing machines are container forming (or open containers), measurement, loading, sealing and other functions.
The typical process: filling machine positioning the hose container, sealing the container after filling by measuring the end, and then sent to the cartoning machine. Cartoning machine first box blank formed, in order to mount the hose wrapped after the push box closed box mouth. Locket by conveyor to install a large box machine stack. Stacking a predetermined number, the big box blank is formed by wrapping a container, which at the same time into the small box, and glue sealing. Large box delivered to the packing machine stack, reaching into the open after a predetermined number of boxes. After packing from sealing stickers will cover sizing sealing machine and flush joints flap affixed to use strapping tape or strapping the box securely.
Liquid filling machine filling principle can be divided by pressure filling machine, pressure filling machine and vacuum filling machines.
Pressure filling machine is a liquid at atmospheric pressure by weight for filling. Such filling machine is divided into regular filling and filling two kinds of constant volume, only applies to gas-free filling of low viscosity liquids such as milk, wine.
Is higher than the pressure filling machine for filling under atmospheric pressure, can be divided into two types: one is the liquid storage cylinder pressure equal to the pressure bottle, by the liquid flow into the bottle and the filling weight, referred to isobaric filling; Another is the liquid storage cylinder pressure is higher than the pressure of the bottle, the liquid into the bottle by the pressure differential, high-speed production lines using this method. Pressure filling machine for filling liquid containing gas, such as beer, soft drinks, champagne and so on.
Vacuum in the bottle filling machine is a pressure below atmospheric pressure for filling. This filling machine simple structure, high efficiency, the viscosity of the material to adapt to a wider scope, such as oils, syrup, wine, etc. can be applied.
The process is generally: with empty boxes stacked on pallets, unloading pallets from the conveyor belt to the machine, remove the tray one by one, the box with the conveyor belt to the unloading boxes machine, remove the vial from the box, empty containers moved by conveyor belts to crate washer, the cleaned and transported to the packing machine next order will be filled with beverage bottles into them. Remove from unloading boxes of bottles machine by a conveyor belt into another bottle washer disinfection and cleaning, inspection machines tested by the bottle, in line with standard of cleanliness after entering the filling machine and capping machine. Beverage into the bottle from the filling machine. Beverage bottles and bottle capper stamped by the seal and transported to the labeling machine labeling, good label affixed to the packing machine after being sent into the box in the stack tray dryer stacked on pallets into the storehouse.
Equipped with a variety of drinks bottles filling lines similar processes. But the drinks are different in nature, using a filling machine and capping machine is also different. Such as beer filling lines in addition to the appropriate choice of filling and capping machine, but also adds a sterilization machine. Capping machine according to the cap (crown cover, cap, lids, etc.) use the appropriate different types of aircraft.
