Eating zongzi on the Dragon Boat Festival and sending zongzi to relatives and friends is a traditional custom of our Chinese people. When technology and transportation were underdeveloped, people encountered the problem that the zongzi were not easy to preserve. It is always given away as soon as it is out of the pot, for fear that the zongzi will deteriorate and rot during transportation.

However, how can this small difficulty stumped the Chinese people, who take food as their priority?

People quickly thought that this difficulty could be solved by simply putting a "coat" on the zongzi - vacuum packaging.

Vacuum-packed rice zongzi have become standard, but there are many cases of air leakage or unsuccessful sealing. During the storage process, the quality of the vacuum seal is particularly important. Improperly stored zongzi will stink and rot.

In order to keep the zongzi for a long time, it is particularly important to use the Automatic Sealing Tester. Because vacuum packaging is also called decompression packaging, it is to extract and seal all the air in the packaging container to maintain a high degree of decompression in the bag. The scarcity of air is equivalent to the effect of hypoxia, so that microorganisms have no living conditions, so as to achieve fresh fruit and disease-free, purpose of corruption.

The sealing performance of the specimen after falling and pressure test can also be testd.
