Introduction to airless bottle

     Vacuum packaging technology is a new concept that is being used by more and more brands ,in order to better keep the activity of active ingredients.

     The contents of the airless bottlecan be completely isolated from the air, avoiding oxidation and deterioration of the product due to exposure to air, breeding bacteria and enhancing the product grade with its high-tech concept. The airless bottle is composed of a cylindrical container with an ellipsoidal shape and a piston placed at the bottom. Unlike standard pumps or spray pumps that are commonly used for straw packaging, vacuum packaging uses the principle of separating the inner cavity to squeeze the contents out. When the inner diaphragm moves upward to the inside of the bottle, a pressure is formed and the contents exist in a vacuum of nearly 100%. However, since the atmospheric pressure cannot give enough force, the piston cannot fit too tightly with the bottle wall, otherwise the piston will not be able to rise due to excessive resistance; on the contrary, if the piston is easy to move forward and prone to material leakage, so the airless bottle has high requirements for the professionalism of the manufacturer. 

    While manufacturers pay attention to the protective and decorative nature of skin care packaging, airless packaging can effectively protect the fresh quality of the product. Once the vacuum packaging is assembled, from the filling of the packaging to the consumer use process, almost minimal air can enter the container and contaminate or decompose the contents. This is the advantage of vacuum packaging - it provides a safe packaging empty vessel for the product, avoiding contact with air, reducing the highly likely changes and oxidation occurring, especially the natural ingredients, in the wave of calls to avoid adding preservatives, vacuum packaging is more important for extending the shelf life of the product, making the product "natural The concept of "natural", "fresh" and "preservative-free" is true to its name.
