Precautions:
Pay attention to the vacuum packaging bag before and after inflation, and don't let sharp objects scratch it. It is best to operate on a bed or a clean desktop. If there are buttons, zippers and other hard objects in the storage, please fold them inward and put them in the collection bag. When storing in cabinets or other places, we should also pay attention to whether there are sharp objects in the storage place to ensure the integrity of the bag.
Vacuum packaging bags and refrigeration. Because the airtight ordinary vacuum bag can't keep fresh, if it is put in the refrigerator, bacteria will also breed, leading to food deterioration. Of course, there are also low-temperature resistant packaging bags, which are generally used to package seafood frozen foods. In short, different materials will have different packaging effects.
