Antistatic Polyethylene Bag Technology: Testing, Performance & Industry Applications – Part 2
5. How Antistatic Additives Work
The working mechanism of antistatic additives is based on controlled surface conductivity:
- Additives migrate to the film surface
- They attract a thin layer of moisture from air
- Moisture increases surface conductivity
- Static charges dissipate safely without sparks
This ensures static control while maintaining safety in sensitive environments.
6. Testing of Antistatic Polyethylene Bags
To ensure consistent performance and regulatory compliance, antistatic PE bags undergo rigorous testing.
Key Testing Methods
| Test | Standard / Method | Purpose |
| Surface Resistivity | ASTM D257 | Measures static dissipation |
| Triboelectric Test | Friction & dust test | Evaluates charge generation |
| Charge Decay Test | Time-based | Measures discharge speed |
| Humidity Conditioning | 40–60% RH | Ensures test accuracy |
Acceptance Range: ✔ 10⁹ – 10¹¹ Ω/□
