Cosmetic Packaging Vacuum But Leak
Nov 22, 2018

The oxygen in the bottle decreases after vacuum, which can prevent the component from oxidizing, stabilize the component activity, and inhibit the survival of the microorganism, so it can prolong the storage time. But care products are liquids and cannot be completely vacuumed like solids, so the extension is limited. In fact, most packages that look sealed are not vacuumed. To determine whether a vacuum bottle is a vacuum bottle, just look at the air holes at the bottom of the bottle. Cover the air hole, will cause no extrusion. Most of the sealed packaging is produced to remove the remaining air, not really vacuum. And our common spray is a design that uses nitrogen to pressurize the bottle, and it's not vacuum.
