Vacuum packaging technology is a new concept, has the absolute advantage.
The packaging technology has helped many new brand and new formula go public.
Vacuum packing once the assembly is completed, the filling packaging consumers to use process, almost negligible air can into the container, pollution or decomposed contents.
This is the advantages of vacuum packaging.
It for the packing of the product provides a safe air, avoid contact with air, reduce is likely to change and oxidation occurred, especially in urgent need of protection and delicate natural ingredients, to avoid a preservative called on opposition, vacuum packaging to extend the shelf life of products more important vacuum packaging of products is different from the usual standards of suction type pump or spray pump, vacuum packaging is to use the principle of separate lumen, squeezing contents.
When the diaphragm move up to the bottle inside, become a pressure, the content is close to 100% of the vacuum.
Another way of vacuum is using vacuum soft bag, placed inside the rigid container, both use concept is almost the same.
The former is widely used, it is very important for brand selling point, because it takes fewer resources, can also be identified as 'green'.
Cosmetics container contents of the vacuum flask and air can be completely cut off, avoid the product due to contact with air oxidation, bacteria, and with its high-tech concept promotion product.
On the market of vacuum flask is made up of a cylinder into spheroid container plus a placed at the bottom of the piston.
Its design principle is to use a contraction of the spring force, and do not let air into the bottle, create a vacuum, and the use of atmospheric pressure to push the bottom of the piston to move forward.
But because of the spring force and the atmospheric pressure can't give enough power, so the piston can't and bottle wall joint is too tight, otherwise the piston will be caused by the rise of resistance to progress;
On the other hand, if you want to get piston is easy going and easy leakage of material condition, therefore the vacuum bottle is very high to the requirement of manufacturers professional.

of vacuum flask is an oval or round shape of the container, and then at the bottom of the bottle have a piston can move freely, the principle of work is to use elastic properties of the spring, and the time of the air inside the bottle, keep a bottle of a vacuum state, then use some of the pressure to make the inside of the bottle piston can then be moved.
Many skincare ingredients are protein, and some amino acid, hyaluronic acid, is easy to let the bacterial contamination, so be sure to pay attention to keep clean, if the pollution, then can produce substances harmful to human body.
And vacuum flask can let the contents and the air off, not easy to oxidizing reaction with air, do not lose the original some effects.
So we can see that the advantages of using vacuum bottle packaging is very much, therefore can be used widely, and as a business if you need this kind of packing, must choose the professional cosmetic plastic containers production company, so as to ensure the quality.
