Pass box is mainly used for the transfer of materials between cleanrooms of different levels, between cleanroom and non-cleanroom. Each type of cleanroom has different requirements for pass box. VCR will provide you pass box requirements in cosmetics cleanroom.

1. Why we need cleanrooms for the production of cosmetics?

In the cosmetics industry, the products are applied to human skin to cleanse, protect, and change people's appearance, thereby making people healthier, younger, and more beautiful.

Dust and contaminants may contaminate the production airspace, possibly causing skin irritation, allergic reactions, and disease. To ensure product quality, cosmetics producers need cleanrooms to carry out production, research, and development activities.

Pass box is an auxiliary device for cleanroom, which reduces cross-contamination. Therefore, using pass box in cosmetics cleanroom is necessary.
