Airless cosmetic bottles, as the name suggests, are different from ordinary lotion bottles. There is no dip tube inside the airless pump bottle. The vacuum piston at the bottom, plus the pressure of the vacuum pump head, sucks out the emulsion in the bottle. The price of airless bottles is slightly higher than that of ordinary PET/PP/PE lotion bottles, so brands will use airless pump bottles for mid- and high-end skin care products, such as natural skin creams, essences, eye creams, face creams, liquid foundations, and makeup lotion.sun protection production and serum.
Relatively speaking, it is mainly used for skin care products/cosmetics applied to the face. When using a new airless dispenser bottle for packaging, you need to press several times to exhaust the excess air before the product is pumped out, and the vacuum pump bottle will not cause the product to return, because it can only go out and not enter, which can fundamentally prevent product contamination and oxidation, thereby ensuring the activity and safety of the product. The material of the airless bottle can be petg, PP, ABS, acrylic, etc.
