How to determine if the vacuum packaging bag is excessively vacuumed?

Vacuum packaging bag is a packaging method that involves adding products into an airtight packaging bag, removing the air inside the bag, and achieving a predetermined vacuum level in the sealed bag. As is well known, insufficient vacuuming of vacuum packaging bags can reduce their effectiveness, but excessive vacuuming of vacuum packaging bags can also cause a decrease in their performance. So how to determine if the vacuum packaging bag is excessively vacuumed?
How to determine if the vacuum packaging bag is excessively vacuumed? Here are some methods to determine if a vacuum packaging bag is excessively vacuumed:
1. Observing the shape of the bag: If the bag is excessively compressed, almost completely attached to the item, and even shows obvious wrinkles, deformations, or stretching marks, it may be due to excessive vacuuming.
2. Check the condition of the items: Check if there are any signs of compression, deformation, or damage to the items inside the packaging, such as breakage of fragile items.
3. Feeling the vacuum pumping force: During the vacuum pumping process, if it is felt that the vacuum pumping equipment requires abnormally high force to continue operating, it may have approached or reached the level of excessive vacuum pumping.
4. Compared with normal situations: If there is previous experience with normal vacuum packaging, it can be determined whether there is abnormal excessive compression by comparing this situation.
5. Check the sealing effect: Excessive vacuuming may cause the sealing area to be subjected to high pressure, resulting in abnormal situations such as unstable sealing and easy breakage.
