Mist Pump Manufacturer introduces that the vacuum bottle is a container that uses the principle of vacuum negative pressure to improve the fine airtightness of the packaging material, and can isolate the gas from the outside temperature or external bacteria.
However, the more sophisticated the container, the more high-quality raw materials, and complex production processes are required, and the price of vacuum packaging containers can reach five to ten times the price of ordinary glass packaging containers!
At present, airless bottles have not yet become popular in the skincare industry, but with the improvement of consumption levels, more and more big brands are gradually using vacuum packaging materials.
The reserved space of the product is mainly to prevent the problem of damage to the packaging such as the expansion of the material body and the ejection of the pump head under extreme weather conditions. Because the vacuum-packaged product does not have a straw, it is necessary to press multiple times to exhaust the air in the packaging material before the discharge body can be pressed during the first use.
In fact, products that use vacuum packaging materials do not require a straw. During the use of the product, as the material body decreases, the sealing gasket at the bottom of the packaging material will gradually rise to the top discharge port. When the bottom gasket is completely lifted to the top, it also means that the product body has been used up.
