HUAZHONG Vacuum Nylon Pouch - 16-month Water Immersion Extreme Test

On June 16, 2023, a rigorous 16-month water immersion test was conducted using our vacuum-sealed nylon bags containing circuit boards, completely submerged in water.

As of October 24, 2024, our examination reveals:

1. The edges and corners of the vacuum nylon bag remain tightly sealed.

2. Internal desiccants remain completely dry.

3. Humidity indicator cards show blue coloration, verifying a moisture-free environment.

These results confirm that the internal environment remains moisture-free. Our vacuum nylon pouches have successfully passed the 16-month water immersion extreme test, and testing will continue.

Note: The vacuum nylon pouches used in this test were randomly sampled from production lines, not specially manufactured for this experiment.
