The filled TORR keg bag should be shipped in the corrugated box that is recommended by TORR.
TORR supply boxes & shipping cases in small and medium lots. Customers can purchase direct from corrugated producers. TORR provide drawings and specifications.
The box flap folding configuration is important to optimize stack strength. Major flap is first, then two minors and then the final major.
Closing the box can be done with tape. Hot melt is stronger but not essential.
The box is designed to be used with an outer shipper that holds 2 x 9 liter boxes for other than local distribution.
