A vacuum bottle refers to a container that can isolate gas from the outside temperature or a container that isolates external bacteria. Its contents can be completely isolated from the air to prevent the product from oxidizing and deteriorating due to contact with the air, and breeding bacteria, and it uses its high-tech concept to upgrade the product level. The vacuum bottle in the market is composed of a cylinder into an ellipsoid container and a piston placed at the bottom. Its design principle is to use the contraction force of the spring to prevent air from entering the bottle, resulting in a vacuum state, and to use atmospheric pressure to push the piston at the bottom of the bottle forward.


The introduction of the airless bottle conforms to the latest development trend of skin care products and can effectively protect the freshness of the product. However, due to the complicated structure of the vacuum bottle and the high cost, the use of vacuum bottle packaging is limited to a limited number of categories of products, which cannot be fully deployed on the market to meet the needs of different grades of skin care products.

While attaching importance to the protection and decoration of cosmetic packaging materials, manufacturers began to focus on the development of the functionality of skin care product packaging, making the concept of "fresh", "natural" and "preservative-free" worthy of the name.


Vacuum packaging technology is a new concept with absolute advantages. This packaging technology has helped many new brands and new formulas go on the market smoothly. Once the vacuum packaging is assembled, from filling the packaging to the consumer's use process, almost minimal air can enter the container, contaminate or decompose the contents. 


This is the advantage of vacuum packaging-it provides a safe packaging empty for products, avoids contact with air, reduces the most likely change and oxidation, especially the delicate natural ingredients that need to be protected, when avoiding the addition of preservatives Among the calls, vacuum packaging is more important to extend the shelf life of products.


Vacuum-packed products are different from standard pumps or spray pumps with common straws. Vacuum packaging uses the principle of separating the inner cavity to squeeze out the contents. When the inner diaphragm moves up to the inside of the bottle, a pressure is formed, and the contents are present in a vacuum state close to 100% at this time. Another way to vacuum is to use a vacuum soft bag, which is placed inside a rigid container. The concept of use of the two is almost the same. The former is widely used and is a very important selling point for brands, because it consumes less resources and can also be regarded as "green".


Vacuum packaging also provides precise dosage control. When the discharge hole and specific vacuum pressure are set, regardless of the matching head shape, each dosage is accurate and quantitative. Therefore, the dosage can be adjusted by changing a certain part, from a few microliters or a few milliliters, all according to the needs of the product. Product preservation and hygiene are the key values of vacuum packaging. Once the contents are taken out, there is no way to put them back into the original vacuum packaging. Because the design principle is to ensure that every use is fresh, safe and worry-free.
