Why the UniHeat 40 Hour Shipping Warmer Matters

Shipping live reptiles and insects safely in cold weather requires a dependable heat source. The UniHeat 40 Hour pack activates when exposed to air and maintains a consistent heat profile throughout its active life. It’s trusted across the reptile industry for its predictable performance, simple use, and proven reliability.

The red stripe across the pack marks the breathing side, where the air holes are located. Always position that side facing open air space inside the box, not against insulation or the container wall. Proper airflow ensures even heating and maximum duration.

If the pack arrives compressed, give it a gentle shake before sealing the box. This loosens the contents and helps the pack activate evenly.

How It Performs in Transit

According to UniHeat’s temperature curve data, the 40 Hour warmer quickly rises to approximately 150°F within the first 6–8 hours, then holds a consistent range between 130°F and 140°F for most of its life. After about 30 hours, it gradually cools down toward 90°F, providing a smooth and predictable decline in heat output—perfect for sensitive live shipments.
