Start with the inside dimensions
Measure the fully packed contents, then allow additional space for cold packs, cushioning and protective bags. Our cooler listings show the usable inside dimensions in inches.
Build your shipping setup
- Select a cooler with enough room for your contents and refrigerants.
- Keep food sealed in suitable leak-resistant packaging.
- Freeze refrigerants according to their instructions before packing.
- Close the insulated lid, then secure the outer corrugated carton.
- Choose a carrier service suited to your product and destination.
Test your route
Temperature performance depends on ambient conditions, refrigerant quantity, product starting temperature and transit time. Validate your complete packout before shipping temperature-sensitive products. No fixed cooling duration is guaranteed by a box size alone.
