Can the vacuum packaging machine extend the shelf life of food? Can the pictures and square characters on the packaging bag be printed together with the packaging machine?

No, the packaging film is printed in advance and sent to the packaging line for food filling, vacuum and sealing
in order to extend the shelf life of food, vacuum packaging must do the following:
First: production. The most important thing is to reduce the presence of bacteria as much as possible in the process of food production. Otherwise, even if the vacuum packaging is good, the food will be rotten due to too many internal bacteria
Second: sealing. The sealing width should be as wide as possible, at least 10mm, and then the sealing temperature should be the test number, not too high or too low. It is easy to burn the breach when it is high, but the sealing effect is not good when it is low. As soon as the air leaks, everything will be finished, and corruption will be accelerated
Third: vacuum bag. Vacuum bags must be better. If you keep them for 2-3 days, you can use 2-3c products casually. However, if you want to keep them for more than a month, you must choose high-quality bags, at least 7-8c bags, otherwise the air will penetrate into them over time

vacuum packaging can indeed extend the shelf life, but it’s not very long. Now it’s only about half a month. It depends on the product processing technology. The pictures are printed by the bag manufacturer when making bags. Does the square character refer to the production date? In that case, there is a hole in the rubber strip sealed by the vacuum machine. Words can be placed in the hole, and the words can be printed on the sealing strip when sealing
