What is the distinguishing feature of cosmetic plastic container material of the vacuum flask

Contents of the vacuum flask and air can be completely cut off, avoid the product due to exposure to 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 cosmetic packaging bottle manufacturers professional. 1, light weight, plastic vacuum flask is lighter material, relative density distribution in 0. 90 - 2. Between the two. Obviously, the plastic can float to the surface of the water? Foamed plastics, in particular, because there a microporous, quality of a material is lighter, relative density is only 0. 01. This makes the plastic can be used to reduce the weight of the product production. 2, excellent chemical stability, the vast majority of plastic of acid, alkali and other chemicals have good corrosion resistance. Especially known as king of plastic polytetrafluoroethylene ( F4) , its chemical stability is better than gold, even in the 'aqua regia' boiled over ten hours also can't bad. Because the F4 has excellent chemical stability, is the ideal of corrosion resistant material. Such as F4 transport corrosive and viscous liquid can be used as the material. Three, excellent electrical insulation properties of common plastics are poor conductor of electricity, its surface resistance and volume resistance is very big, with Numbers of up to 109 a 1018 ohms. The breakdown voltage, dielectric loss Angle tangent value is very small. As a result, the plastic in the electronic industry and mechanical industry has been widely used. Such as plastic insulated control cables. Cosmetic plastic container contents of the vacuum flask and air can be completely cut off, avoid the product due to exposure to air oxidation, bacteria, and with its high-tech concept promotion product.

Cosmetics container launch complied with to protect skin to taste the new development trend of vacuum flask, can effectively protect the fresh quality products. , but due to the complexity of the vacuum flask structure, higher cost of vacuum bottle packaging the use of only a few categories of goods, cannot be carried out in the market, to meet the needs of different class cosmetics packaging. in take skin care cosmetics packaging protective and decorative, began to focus on developing functional skin care products packaging, make the product of 'fresh', 'natural', the concept of 'preservative-free' worthy of the name. 449.
