Vacuum Cosmetics Packaging

1) Background of vacuum cosmetics packaging

With the development trend of skin care products "fresh", "healthy", "natural", "green" and "preservative free", the formulas of products has become more complex and unstable. Formulas could be sensitive to oxidation, air, ultraviolet, and pollution. The high viscosity of some formulas requires more accurate dosage, high emptying rate.

Vacuum packaging can effectively protect products by insulating products from outside air, preventing formula from oxidation and deterioration, pollution and breeding of bacteria due to contact with air.

2) Classification of vacuum cosmetics packaging

Generally speaking, vacuum packaging for cosmetics can be divided into two categories,

One is piston vacuum packaging (piston system), the other is bag /tube vacuum packaging (bag /tube system)

Vacuum packaging is generally composed of vacuum pump, vacuum bottle (base, piston, bottle body) or vacuum bag (tube). Taking piston vacuum packaging as an example, the cooperation between piston and bottle wall is very precise during working process. If it is too tight, the piston cannot rise and move forward due to excessive friction; If it is too loose, it is prone to leak and result in low emptying rate. Therefore, vacuum packaging requires very high manufacturing precision and professionalism of the supplier.

3) Working principle of vacuum cosmetics packaging

The working principle of vacuum packaging is generally to press down the vacuum pump to discharge inner formula, and do not allow air to enter the packaging during operation, so that there is a vacuum negative pressure state in the packaging, and use the external atmospheric pressure difference to push the piston at the bottom of the bottle forward or squeeze the soft bag (tube) to achieve the purpose of discharging. airless principle.jpg

4) Filling of vacuum cosmetics packaging

Filling is an important process in vacuum packaging production, and it is also directly related to the final use effect.

According to the position of filling port, it can be divided into top filling and bottom filling. According to the working conditions of filling, it can be divided into atmospheric pressure filling and vacuum filling. The pre-defoaming treatment of formula before filling is very important. If it is not handled well, it may lead to poor start-up and small filling capacity. In addition, the physical parameters of the material (density, dynamic viscosity, surface tension etc.) may have a certain impact on the use of vacuum packaging, which should be evaluated through relevant experiments and tests.
