  Why need vacuum packaging?

 

  Everyone knows that no matter for any food, there is a certain shelf life. Moreover, the shelf life of most foods is very short, so many foods are vacuum-packaged, let’s talk about why vacuum packaging is needed.

 

Why do we need vacuum packaging

 

  Vacuum packaged food can extend the shelf life of food

 

  After vacuum-packed food, the air inside is scarce, which is quite low in oxygen. Microorganisms cannot survive in this environment, so the food can be fresh and not easily deteriorated.

 

  Vacuum packaging can protect food more effectively

 

  After vacuum packaging, it has the functions of anti-pressure, gas-barrier and fresh-keeping, which can more effectively keep the original color, fragrance, taste, shape and nutritional value of the food for a long time. In addition, there are many foods that are not suitable for vacuum packaging, but must be vacuum-filled packaging. Such as crispy and fragile foods, foods that are easy to agglomerate, foods that are easy to deform and run out of oil, foods with sharp edges or corners or high hardness that will pierce the packaging bag, etc. After the food is vacuum-inflated and packaged, the inflation pressure inside the packaging bag is stronger than the atmospheric pressure outside the packaging bag, which can effectively prevent the food from being crushed and deformed under pressure, and does not affect the appearance of the packaging bag and the printing and decoration.
