The previous post had an introduction toCosmetic Packaging Glass Bottles的知識，相信大家有化妝品包材有一定的初步的了解，但是化妝品包裝材質(zhì)，類(lèi)型眾多，在學(xué)習的道路上還有漫漫長(cháng)路，需要各位繼續堅持，今天來(lái)學(xué)習一些關(guān)于真空瓶的的知識點(diǎn)。

vacuum flaskIt is a kind of container that can isolate the gas from the outside temperature or isolate the external bacteria. Its contents and air can be completely isolated to avoid product oxidation and deterioration due to contact with air, breeding bacteria, and with its high-tech concept to enhance the product grade. The vacuum bottle prevailing in the market is composed of a cylinder into an ellipsoid container plus a piston placed at the bottom. Its design principle is to use the spring contraction force, and do not let the air into the bottle, resulting in a vacuum state, and the use of atmospheric pressure to promote the bottom of the bottle piston forward. However, due to the spring force and atmospheric pressure can not give enough power, so the piston can not be too tight with the bottle wall, otherwise the piston will not be able to rise due to excessive resistance to move forward; on the other hand, if you want to make the piston easy to move forward and easy to leakage, so the vacuum bottle on the professionalism of the manufacturer's requirements are very high.

Cosmetic packaging material knowledge of the vacuum bottle introduction

真空瓶的推出順應了護膚品最新發(fā)展趨勢，能夠有效保護產(chǎn)品新鮮質(zhì)量。但是由于真空瓶結構復雜，成本偏高，對真空瓶包裝的利用僅限于有限幾個(gè)類(lèi)別的產(chǎn)品，無(wú)法在市場(chǎng)上全面鋪開(kāi)，來(lái)滿(mǎn)足不同檔次護膚品包裝的需要。

Manufacturers in the emphasis on the protective and decorative cosmetic packaging materials at the same time, began to focus on the development of the functionality of skin care packaging, so that the product's "fresh", "natural", "preservative-free The concept of "fresh", "natural" and "preservative-free" products is true to its name.

vacuum packagingThe technology is a new concept with absolute advantages. This packaging technology has helped many new brands and formulas make it to market. Once vacuum packaging is assembled, from filling to consumer use, there is virtually no air that can enter the container and contaminate or break down the contents. This is the advantage of vacuum packaging - it provides a safe packaging vessel for the product, avoiding contact with air and reducing the high likelihood of change and oxidation, especially for delicate natural ingredients that need to be protected, which is even more important for extending shelf life amidst calls to avoid adding preservatives.

Vacuum-packed products are different from the common straw-type standard pumps or spray pumps, vacuum packaging is the use of the principle of separation of the inner chamber, the contents of the extrusion of the discharge. When the inner membrane moves upward to the inside of the bottle, a pressure is formed, at which time the contents are present in a vacuum state close to 100%. Another type of vacuum is the use of vacuum soft bags, placed inside rigid containers, the two concepts of use are almost the same. The former is widely used and is an important selling point for brands, as it uses fewer resources and can also be recognized as "green".

Vacuum packaging also provides precise dosage control. Once the outlet holes and specific vacuum pressure have been set, the dosage is precise and quantitative, regardless of the shape of the supporting indenter. Therefore, the dosage can be adjusted by changing a certain part, from a few microliters to a few milliliters, depending on the needs of the product. Product freshness and hygiene are key values in favor of vacuum packaging. Once the contents have been removed, there is no way to put them back into the original vacuum package. Because the design principle is to ensure that each use is fresh, safe and worry-free, the internal mechanism of our products has no spring rust to worry about and will not contaminate the contents.

Vacuum bottle packaging styles vary, each customer's preference is different, customers can be based on the brand positioning of the consumer level and the crowd to choose the appropriate vacuum bottle style, the general price of vacuum bottles will be relatively high, but also due to the different styles will be different, customers can be based on the brand positioning of the appropriate choice!
