Will juice boxes explode in checked luggage?

Juice boxes may explode or leak in checked luggage, depending on several factors:

1. Air pressure changes
When an airplane takes off and lands, the air pressure in the cargo hold changes. Although modern aircraft cargo holds are usually pressurized, the pressure may still be lower than on the ground. The liquid and air in the juice box will expand due to the reduced pressure. If the box is not sealed well or there is insufficient space for expansion, it may burst or leak.

2. Packaging quality
If the juice box is paper or soft packaging, and the sealing performance is average, it is more susceptible to air pressure and burst. In contrast, hard plastic or aluminum containers are more durable, but you still need to pay attention to whether there is room for capacity.

3. Storage method
Juice boxes may burst due to external force when they are pressed under other luggage. It is recommended to pack them properly to avoid external damage.

How to prevent juice boxes from exploding or leaking?

Choose hard containers: more resistant to pressure than soft packaging.

Leave room for expansion: Do not overfill the juice box, and make sure there is enough room in the box to accommodate the expansion of the liquid.
Secondary protection: Separate juice boxes in plastic bags or waterproof bags to prevent leakage.
Pre-check: Make sure the packaging is not damaged and the lid is tightened or sealed securely.

Juice boxes may explode in checked luggage, but the risk can be greatly reduced with the right protective measures. If possible, it is recommended to carry the juice with you and avoid checking it.
