Basic Functions of Vacuum Bags

Have you ever wondered why the potato chips sold in supermarkets can stay crispy? Why don't clothes get wrinkled when you put them in a suitcase when traveling? The secret may be hidden in that inconspicuous plastic bag - the vacuum bag.


A vacuum bag is like a magician who can "suck air". After it removes the air in the bag, the remaining space becomes particularly "obedient". For example, when packing food, without air, bacteria and mold have no chance to make trouble, and the food preservation time is directly doubled. When you are on a business trip, put your down jacket in it, and the volume can be reduced by half after the air is pumped out, and the suitcase will instantly have more space for shoes.

What's more amazing is that it can also prevent moisture and oxidation. Camera lenses, stamp collections, and even important documents, as long as they are packed in a vacuum bag, humid air and oxygen cannot enter, and the things will look like they were just bought after being stored for several years. But please note that it is not possible to pack liquids or living things. The "magic" of vacuum bags only works on solid objects!
