Built-in Antistatic PET for Thermoforming
Yuanle supplies PET sheet with antistatic properties incorporated into the material rather than applied as a surface coating. The built-in approach supports antistatic performance after thermoforming, including stretched areas.
- Antistatic performance: 3 years for the specified grade and conditions.
- Electrical range: 104–1010. Confirm the selected grade, measurement method, unit and test conditions before ordering.
- Heat resistance: third-party laboratory testing of empty thermoformed trays at 82°C for 24 hours showed no deformation under the tested conditions.
The temperature result applies to the tested empty trays. Loaded packaging, different thicknesses or different forming geometries require application-specific validation.
