When the product is shrinkable, remember to empty the air in the packaging film, so as to make the packaged products reach a vacuum state, which is conducive to the long-term preservation of goods.
But sometimes if the vacuum packaging machine has some problems or incorrect operation and other reasons, it is also very easy to have a bad pumping effect, which deserves our attention.
Automatic vacuum packaging machine is the use of vacuum packaging film for products to implement vacuum packaging, so the quality control of vacuum packaging film is very key.
We must use qualified quality and vacuum packaging film with a certain thickness. In the preservation process before we use it and the packaging process in the use, we need to ensure that the vacuum packaging film will not be damaged and cause air leakage.
Secondly, it is necessary to ensure that the food vacuum packaging machine has sufficient pumping time when packaging the products, so as to ensure that the air in the packaging film can be fully evacuated and the internal vacuum degree can be guaranteed.
Sealing control time is not to early sealing, to avoid the existence of residual air in the packaging film.
The quality of the sealing should be guaranteed, and the sealing should be fully dense and closed, so as to avoid the occurrence of air leakage and affect the vacuum degree in the vacuum packaging film.
The core part of the vacuum packing machine is the vacuum pump. When working for a long time, dust and stolen goods are easy to enter the vacuum pump, making the packaged products stick with dust and stolen goods. At this time, the vacuum pump must be replaced with oil.
Frequent change of oil can enhance the pumping effect of small vacuum packing machine.
We also need to pay attention to the protection of the pressure air bag inside the vacuum packing machine, to prevent it from cracking, and can not achieve a good pumping effect.
