[Packaging materials] Basic knowledge of vacuum bottles

The contents of the vacuum bottle can be completely isolated from the air, avoiding the oxidation and deterioration of the product due to contact with the air, breeding bacteria, and improving the product file with its high-tech concept. The vacuum bottle commonly used in the market consists of a cylindrical ellipsoid container with 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, resulting in a vacuum state, and use atmospheric pressure to push the piston at the bottom of the bottle forward. However, due to the spring force and atmospheric pressure can not give enough force, so the piston can not be attached to the bottle wall too tightly, otherwise the piston will be unable to rise due to excessive resistance; on the contrary, if the piston is easy to move forward, it is easy to leak material, so the vacuum bottle has very high professional requirements for manufacturers.

The introduction of vacuum bottles conforms to the latest development trend of skin care products and can effectively protect the fresh quality of products. However, due to the complex structure and high cost of vacuum bottles, the use of vacuum bottle packaging is limited to a limited number of categories of products, and cannot be fully rolled out in the market to meet the needs of different grades of skin care packaging.

While paying attention to the protection and decoration of skin care products packaging, manufacturers began to focus on the development of the functionality of skin care products packaging, so that the concept of "fresh", "natural" and "preservative free" of products is worthy of the name.

Vacuum packaging technology is a new concept, has an absolute advantage. This packaging technology has helped many new brands and new formulations go to market smoothly. Once the vacuum package is assembled, almost minimal air can enter the container and contaminate or decompose the contents during the self-filling package to the consumer. This is the advantage of vacuum packaging-it provides a safe packaging space for products, avoids contact with air, reduces the possibility of changes and oxidation, especially the urgent need to protect and delicate natural ingredients, in the call to avoid adding preservatives, vacuum packaging is more important to extend the shelf life of products.

Vacuum packaging products are different from the standard pump or spray pump of the common suction tube type. Vacuum packaging uses the principle of separating the inner cavity to squeeze the contents out. As the inner membrane moves upward into the interior of the bottle, a surge of pressure is created, at which point the contents are present at a vacuum of nearly 100 percent. Another vacuum way is to use a vacuum soft bag, placed inside the hard container, the two use concept is almost the same. The former is widely used and is an important selling point for brands because it consumes less resources and can be considered "green".

Vacuum packaging also provides precise dosage control. When the discharge hole and the specific vacuum pressure are set, each dosage is accurate and quantitative regardless of the matching indenter shape. Therefore, the dose can be adjusted by changing a part, 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 vacuum packaging. Once the contents are taken out, there is no way to return to the original vacuum packaging. Because the design principle is to ensure that every use is fresh, safe, and worry-free, the internal mechanism of our products has no doubts about spring rust, and will not pollute the contents.

Consumer awareness, in the invisible also affirmed the value of vacuum products. Compared with the general standard pumps, sprays, straws, and other packaging components, vacuum packaging is used smoothly, with fixed dosage and high-grade appearance, making it a huge market for luxury products.
