1. About airless bottles

  The contents of the airless bottle can be completely blocked from the air, preventing the product from oxidizing and metamorphosing and breeding bacteria due to the touch of the air, and improving the product file with its high-tech concept. The vacuum bottle used in shopping malls is composed of a cylinder into an ellipsoid container and a piston with a settled bottom. Its planning principle is to use the shortening force of the tension spring, and to prevent air from entering the bottle, causing a vacuum condition, and using atmospheric pressure to push the piston at the bottom of the bottle forward. However, because the tension spring force and atmospheric pressure cannot provide sufficient force, the piston cannot be too tightly attached to the bottle wall, otherwise the piston will not be able to move forward due to excessive resistance; on the contrary, if the piston is to move forward easily, it is prone to leakage. Therefore, the vacuum bottle has very high requirements for the professionalism of the manufacturer.
  The introduction of the airless bottle conforms to the latest development trend of skin care products and can effectively protect the freshness and quality of products. However, because of the complex structure and high cost of airless bottles, the use of airless bottle packaging is limited to a limited number of categories of products, and cannot be fully deployed in the market to meet the needs of different levels of skincare packaging.
  While focusing on the protection and decoration of skin care and skin care products, manufacturers began to develop the functionality of skin care products, so that the concept of "fresh", "natural" and "preservative-free" of the products deserved.
2. Vacuum packaging skills
  Vacuum packaging skills are a new concept with absolute advantages. This packaging skill has helped many new brands and new formulas to be launched smoothly. Once the vacuum packaging is assembled, from filling the packaging to the customer's use process, almost minimal air can enter the container to contaminate or differentiate the contents. This is the advantage of vacuum packaging-it provides a safe packaging empty device for the product to prevent contact with the air, the most likely change and oxidation occurs, especially the delicate natural ingredients that are in urgent need of protection, to prevent the increase of preservatives Among the calls, vacuum packaging is more important for extending product shelf life.
  The vacuum-packed products are different from the common standard suction pipe type pumps or spray pumps. The vacuum packing uses the principle of dividing the inner cavity to knead and discharge the contents. When the inner diaphragm moves up to the inside of the bottle, a pressure is formed. At this moment, the contents are in a vacuum state close to 100%. Another vacuum method is to use a vacuum soft bag and place it inside a rigid container. The concept of the two applications 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 considered "green".
  Vacuum packaging also provides accurate dosage control. When the discharge hole and specific vacuum pressure are set, regardless of the matching head shape, the dosage is accurate and quantitative each time. Therefore, the dosage can be adjusted by changing certain parts, 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 recommended vacuum packaging. Once the contents are taken out, there is no way to put them back into the original vacuum packaging. Because the principle of planning is to ensure that every application is fresh, safe, and worry-free. The internal organization of our products has no doubts about tension springs and rust, nor will it contaminate the contents.
  Customers' perceptions also affirm the value of vacuum products invisibly. Compared with general standard pumps, sprays, straws, and other packaging components, vacuum packaging is smoothly used, fixed in dosage, and high-end appearance, making it occupy a large market for luxury products.
