Why Bursting Strength Testing Matters
Bursting strength measures the maximum hydraulic pressure a sheet material can withstand before rupture. This parameter is critical for:
- Ensuring carton and box integrity during stacking and transportation
- Reducing product damage and customer returns
- Meeting international packaging standards and customer specifications
