After using the vacuum packaging machine for a period of time, it was found that the vacuum lid could not be sucked. At this time, you can check the machine whether has following problems.

For dry products such as rice and bacon, the vacuum pump oil can be changed once every 6-12 months.

When opening the vacuum lid, the vacuum lid will slowly bounce up. If it is too fast or too slow, something must be wrong.

One of my customers complains that the sealing part is burned or air leak when they are working with packages 10kg bags. But the problem disappears when packages <5kg. Checking for many times, I find the key reason.

Unattractive packaging can sometimes affect the sales of products, just like A in the picture. So how to improve it?
