Products Description

Dual-purpose compact powder jar: This powder jar separates powder and powder puff, that is, the puff is prevented from being contaminated by the powder, and the ventilation design is also required.

The airtight function of the airtight compact powder jar is mainly to protect the volatile foundation from drying out during use. In recent years, with the development of the airtight BB cream compactor, the design of the airtight structure has gradually adopted the bi-injection process, and the seals are injection molded of soft and hard materials (such as TPE+PP) to achieve better airtightness requirements.There are also some products that use the vacuum pump to achieve a better airtight effect, while relatively the cost increases.

Materials of Plastic Powder Jar:

While SAN, PCTA and PMMA is mostly used for transparent parts, while PCTA is more suitable for powders requiring higher chemical resistance. The PP material is soft and can be used in a one-piece powder jar or powder jar with sealing required.
