08月12 A Brief Description of The Packaging Process
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.
