Antistatic Additives for Plastic Packaging Films & Containers
Static charge on plastic packaging attracts dust, causes handling problems, and can damage sensitive electronic components - antistatic additives solve all three.
Why Plastics Build Up Static
Most plastics are natural insulators, so friction during handling, unwinding or filling generates static charge that has nowhere to dissipate. This causes films to cling together, attracts dust to packaging surfaces, and in electronics packaging, poses a real risk of electrostatic discharge (ESD) damage to sensitive components.
How Antistatic Additives Work
Antistatic additives migrate to the polymer surface over time and attract a thin layer of atmospheric moisture, which forms a conductive path that allows static charge to dissipate rather than build up. Internal (migratory) additives are compounded directly into the resin, while some applications use topical or permanent antistatic masterbatch for consistent, long-lasting performance.
Common Applications
Antistatic formulations are widely used in:
- Electronic component packaging bags and trays (ESD-safe packaging)
- Stretch and shrink films for palletised goods
- Injection-moulded containers for powders and granules
- Woven sacks and liners for dust-sensitive materials
Choosing the Right Grade
Selection depends on the base resin (PP, PE, HDPE), required surface resistivity, and whether the effect needs to be permanent or is acceptable as a slower-migrating internal additive. Our technical team matches the additive package to your resistivity target and shelf-life requirement.
