Different products in the specification of packaging requirement for its packaging technology and packaging configuration is different, so the packaging industry in the design of
packaging machine also need to design according to the needs of different users have different varieties, to meet the packaging needs of many industries, and achieve better development.
So, here to introduce for everybody four kinds of classification of vacuum
packaging machine.
A mechanical extrusion, vacuum packaging machine, in front of the mouth sealed from the bag on both sides with spongiform item exclude air bag, and then heat sealing mouth.
This kind of mechanical vacuum method is simple, but the vacuum degree is low.
2, outside pulling type
packing machine from the bag opening into the exhaust pipe, open the suction valve, vacuum pump suction, and sealing.
For inflatable, can be in after extraction by gas charging valve filling the need, and then seal.
This machine structure is simple, but not too high vacuum degree.
Such as breath, can achieve more ideal effect.
Three, room type
packing machine in the packaging, the items will be equipped with plastic bags in a vacuum chamber, close cover extraction, to the expected after the vacuum degree of the heat sealing device is closed, the mouth sealed.
As for vacuum packaging, filling the gas before sealing.
The vacuum packaging machine vacuum degree is high, can according to need to adjust the vacuum degree, is the more used one.
Four, thermoforming packaging machine also called continuous or deep drawing vacuum packaging machine.
It is adopt the method of sheet in the model of hot forming, homemade packaging container on the packing, and then finish filling, capping, vacuum, gas, transverse and longitudinal cutting, until the finished product output.
Above is mechanical extrusion type vacuum packer, outside pumping room type packing machine, packaging machine, thermoforming packaging machine and so on four kind of vacuum packaging machine packaging method and characteristics is introduced, the four types of packaging machine according to the different way of packing, but also have different performance in many other aspects, when the choice we need to choose according to different product packaging requirements of different, to ensure the quality of packaging eligibility.
