about vacuum flask, vacuum flask contents 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.





vacuum packaging technology

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 packing - 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 is more important.

vacuum packaging of product is different from the usual standards of suction type pump or spray pump, vacuum packing 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 considered & other; Green environmental protection & throughout; 。

the dosage of the vacuum packaging and at the same time to provide accurate control, when discharging hole and specific vacuum pressure set good, no matter why the pressure head shape of form a complete set, each time the dosage is precise and quantitative. Therefore, can be adjusted by changing some parts dose, from a few or a few ml, all in accordance with the requirements of product adjustment.

product preservation and health as the key value of vacuum packing, once the content is removed, there is no way to put back the original vacuum packaging. Due to the design principle is to ensure that the use of each are fresh, safe, secure, internal institutions of our products, no spring rusting, nor pollution to the contents.

consumer cognition, in virtually certain vacuum products value too. With general standard pumps, spray, straws, compared to the packaging components such as the use of vacuum packaging, dosage is fixed, high-grade appearance, make it occupy large market luxury products.
