What is the design principle of airless bottles

The contents of the vacuum bottle of China YAKIN packaging can be completely isolated from the air, to prevent the product from being oxidized and deteriorated due to contact with the air, and to breed bacteria, and to upgrade the product file with its high-tech concept. Usually the vacuum bottle in the market is composed of a cylinder into an ellipsoid container and a piston placed at the bottom.

Its design principle is that the vacuum lotion bottle manufacturer uses the contraction force of the spring to prevent air from entering the bottle, resulting in a vacuum state, and uses atmospheric pressure to push the piston at the bottom of the bottle forward. However, because the spring force and atmospheric pressure cannot give enough force, the piston cannot fit too tightly with the bottle wall, otherwise the piston will not be able to move forward due to excessive resistance; on the contrary, if the piston is to be moved forward easily and material leakage is likely to occur, Therefore, vacuum bottles have very high requirements for the professionalism of vacuum lotion bottle manufacturers.

Plastic bottle vacuum packaging technology originated in the 1940s. Since the successful application of polyester and polyethylene plastic films to commodity packaging in 1950, vacuum packaging technology has developed rapidly. my country's vacuum packaging was developed in the early 1980s, although it was later than European developed countries, but with the rapid development of my country's vacuum packaging, vacuum packaging technology has continued to improve.

Vacuum packaging technology was first applied to food packaging, and then gradually introduced into the pharmaceutical packaging and cosmetic packaging industries. At the initial stage, the vacuum packaging technology of cosmetics was basically mastered by foreign-funded enterprises. In the late 1990s, my country's cosmetic vacuum packaging began to enter a period of rapid development, and related domestic companies have sprung up like bamboo shoots after a rain.

The selection of cosmetic packaging basically includes five elements: product compatibility, seal integrity, barrier integrity, appearance appreciation, and physical properties in circulation. The integrity of the seal (that is, the airtightness of the package) is particularly important, because the active ingredients in most cosmetics are extremely volatile compounds, and many natural ingredients are easily discolored and deteriorated when exposed to air. High-end brands choose vacuum packaging not only for aesthetic reasons. Many high-end brands of skin care products have very advanced formulations and have specific requirements for vacuum packaging, so they need to be optimally protected.

The vacuum pump and the bottle body need to be easily evacuated, the liquid distribution amount is uniform, and the internal space is reduced with the reduction of the material body, which isolates the outside air from entering, and the packaging has a beautiful appearance. Consumers can dispense the products in the package at any position and angle, realizing a 360º omni-directional application without dead ends.
