As we all know, many skin care brands develop various lotions and essence products which are contained many active ingredients. These active ingredients (such as vitamin C, 377, amino acids, protein, etc.) and common skin care ingredients (such as glycerin, minerals, oils, etc.) are all nutrients required for bacterial growth. Oxygen and water are the keys to the growth of bacteria. For example, when the double-bond part of unsaturated fatty acid in oil meets oxygen, an addition reaction (a characteristic reaction of unsaturated compounds) will occur to generate peroxide, and then continue to decompose low-molecular aldehydes and carboxylic acids with special odors.
The process of manufacturing skin care products is not in a vacuum environment. General skin care product manufacturers add preservatives to prevent contamination from the raw materials. However, with the continuous improvement of consumers’ living standards, more and more attention is paid to the composition requirements of products, and consumers have begun to pursue more effective and pollution-free skin care products. So, besides adding preservatives, what better way is there? One of the methods is to pump the air to reduce the contact between the contents and the air, which will keep the product fresh. The airless bottle was born for this purpose.
Advantages of airless bottles
- Airless bottles can prevent sensitive products (such as natural skin creams, essences, foundation creams, and other preservative-free formula creams) from being exposed to the air, thereby protecting their lifespan by up to 15%. This makes vacuum technology the new future of skincare, beauty, and medical packaging.
- The cosmetic airless bottle does not have a dip tube, but a diaphragm that rises to evacuate the product. When the user presses the pump, a vacuum effect is created, pulling the product upward. Consumers can use almost all products without leaving any waste.
- In addition to protecting your formula and extending the shelf life, the airless bottle also provides a brand effect. This is a high-end packaging solution with various designs that can meet your aesthetic positioning.
Production of airless bottles
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, creating a vacuum state, and to use atmospheric pressure to push the piston at the bottom of the bottle forward. However, because the spring force and atmospheric pressure cannot give enough power, 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 be moved forward easily and material leakage is likely to occur, Therefore, airless bottles have very high requirements for the professionalism of manufacturers.
Somewang Packaging focuses on providing innovative packaging solutions for various uses. Our team of engineers has accumulated rich experience in decades of vacuum packaging research and development.
For example, the Somewang Min size airless bottle provides a non-contact air space to keep the contents fresh and support long-term storage. This is especially suitable for brands that pursue product professionalism and consumer favorability.
Somewang mini airless bottles are widely used in the packaging of creams, lotions, essences, and oils, and are your first choice. Somewang provides more choices to meet your appearance needs, such as custom colors, color printing/hot stamping, gradient colors, electroplating, matte and glossy.
