Why the UniHeat 60 Hour Shipping Warmer Matters

When shipping across multiple states or during colder seasons, reliable temperature control is essential. The UniHeat 60 Hour warmer offers stable performance designed to keep boxes comfortably warm for the entire journey.

It’s a favorite among plant growers and nurseries, who rely on its endurance for extended ground shipments or weekend delays. The pack’s gradual warm-up and balanced heat output protect delicate leaves, roots, and stems from cold damage — while still performing safely for live reptiles and insects.

How the UniHeat 60 Hour Shipping Warmer Performs in Transit

Activation begins within about 30 minutes after exposure to air. The warmer gradually rises to a peak surface temperature of approximately 130–135°F (54–57°C) at around the 12-hour mark.

It then maintains a steady warmth in the 115–125°F (46–52°C) range for more than 36 hours before slowly tapering off after the 50-hour point. This gentle, controlled temperature profile helps protect temperature-sensitive shipments from cold stress without overheating.

The red stripe marks the breathing side, where the air holes are located — always face this side toward open space inside the box, not against walls or lids, for consistent airflow and even heating.

Pro Packing Tip

For best results, use inside a Styrofoam-lined or insulated box. Pair with a PhazeLock PCM 23 Gel Phase Pack to maintain balanced internal temperatures and prevent temperature swings during transit.

Give it a quick shake before use — it helps air get in and activates more evenly.

Before shipping, check current U.S. weather alerts to avoid temperature extremes or carrier delays.
