How to choose food vacuum packaging bags correctly?

Time flies, and in the blink of an eye, it has once again arrived at the annual New Year's shopping season. With the improvement of people's quality of life and the enhancement of health awareness, food packaged in vacuum bags is becoming increasingly trusted. So, how to choose food vacuum packaging bags correctly?
How to choose food vacuum packaging bags correctly? Jinde Packaging introduces that food vacuum packaging bags are used to extract and seal the air inside the food packaging bag, maintaining a highly depressurized state inside the bag, which is equivalent to a low oxygen effect, making it impossible for microorganisms to survive, preventing food from moldy and spoiled, effectively isolating air from oxidation, and maintaining the color, aroma, and nutritional value of food. It is worth noting that food vacuum packaging bags themselves do not have bactericidal effects. To truly utilize the advantages of vacuum packaging technology, necessary processing is required after vacuum packaging is completed. Perishable and refrigerated foods still need to be refrigerated or frozen after vacuum packaging, and the vacuum preservation period of ingredients stored at different temperatures varies. Vacuum packaging is not a substitute for refrigeration or freezing preservation. Whether the bag is swollen or not is a more intuitive and convenient way for consumers to judge whether food vacuum packaging has spoiled.
1. Under normal circumstances, the air pressure inside a food vacuum packaging bag is the same as the outside or lower than the outside after vacuuming. If the bag swells, it indicates that the air pressure inside the bag is higher than the outside, which means that new gases have been generated inside the sealed packaging bag. These gases are metabolic products produced by a large number of microorganisms after reproduction, because a small amount of microbial metabolites are not enough to inflate the bag.
2. Never use the smell of food as a criterion for evaluation. If the food odor spills out of the packaging, it means that the vacuum packaging itself is no longer vacuum and there is an air leak. This means that bacteria can also freely 'flow'.
3. To check if the production license, SC code, manufacturer, and ingredient list on the food vacuum packaging bag are complete. These certificates are like the "identity cards" of food, containing the "past and present" of food, where it came from and where it has been. The Food Safety Law clearly stipulates that food packaging should be labeled with the food production license number, which is composed of the letters "SC" and 14 Arabic numerals. The "SC" code represents the license code of the enterprise and can achieve food traceability.
4. Consumers should strictly pay attention to the shelf life of food. Food that is close to its expiration date does not necessarily mean it is harmful, but its color and nutrition will decrease. After opening the vacuum packaged food bag, it should be consumed as soon as possible and should not be stored in the refrigerator again. When choosing "buy one get one free" food, pay attention to the production date and shelf life of the bundled products.
