Understanding Export Shipping Stresses
Export shipments face extended transit times, rough handling, container stacking, and climate exposure that demand superior box strength.
Box Strength Ratings Explained
Edge Crush Test (ECT) measures stacking strength, while burst strength measures face durability. Export boxes typically require 44 ECT or higher.
Single Wall vs Double Wall for Export
Double wall corrugated boxes are the minimum standard for export packaging. Single wall rarely survives international shipping.
Environmental Exposure
Humidity and temperature fluctuations weaken low-grade corrugated. Export-grade boxes resist moisture-induced degradation.
Testing Export Packaging
ISTA export protocols simulate vibration, compression, and drop stress to validate box performance.
Best Practices for Export Box Selection
- Use double wall construction
- Specify ECT 44 or higher
- Add moisture protection
- Verify regulatory compliance
