The introduction of vacuum bottles conforms to the latest development trend of skin care products, which can effectively protect the fresh quality of products. However, due to the complicated structure of the vacuum bottle and the high cost, the use of the vacuum bottle packaging is limited to a limited number of products, and cannot be fully spread in the market to meet the needs of different grades of skin care packaging.
While paying attention to the protective and decorative properties of cosmetic packaging materials, manufacturers began to focus on the development of the functionality of skin care packaging, so that the concept of "fresh", "natural" and "preservative-free" is worthy of the name.
Vacuum packaging technology is a new concept with an absolute advantage. This packaging technology has helped many new brands and new formulations go on the market. Once the vacuum packaging is assembled, from the filling of the package to the consumer's use, almost minimal air can enter the container, contaminating or decomposing the contents. This is the advantage of vacuum packaging - it provides a safe packaging for the product, avoiding contact with air, reducing the possibility of changes and oxidation, especially the need to protect and delicate natural ingredients, avoiding the addition of preservatives In the call for sound, vacuum packaging is even more important for extending the shelf life of the product.
The vacuum-packed product is different from the standard suction pump or the standard pump. The vacuum packaging uses the principle of separating the inner cavity to squeeze out the contents. When the inner membrane moves up to the inside of the bottle, a pressure is formed, at which time the contents are present in a vacuum close to 100%. Another vacuum method is to use a vacuum pouch placed inside a rigid container, the concept of which is almost the same. The former is widely used and is an important selling point for the brand because it consumes less resources and can be considered as “green”.
