1. Why Drop Testing Matters
Testing ensures:
Shape retention
No cracking
No tearing
No density collapse
Essential for online retail where packaging may experience rough handling.
2. Drop Test Procedure
Standard Method
Drop from 1 meter
Onto a flat surface
Repeat 5¨C10 times
What Factories Inspect
No visible dents
No tears
Stable elasticity
3. Additional Stress Tests
Compression test (50¨C100 cycles)
Wet expansion drop test
Tear strength test
4. Buyer Requirements
Brands should request:
Video proof
Batch test data
Written QC report
Conclusion
Drop tests guarantee product resilience during transportation and daily use. Buyers should ensure their suppliers follow structured testing to maintain quality consistency.
