Description
PhazeLock 23° Gel Phase Pack
Organic PCM temperature control for safe, stable shipping
The PhazeLock 23° Gel Phase Pack is an organic phase pack for shipping that keeps your shipments within a safe temperature range by maintaining a consistent 23°C (73°F) environment during transport. Each pack contains an organic, non-toxic Phase Change Material (PCM) that stabilizes heat through solid-solid and gel-solid phase transitions. These changes actively absorb or release energy, preventing temperature swings that could harm your shipment.
Built for All Seasons
Whether it’s warm or cold outside, you can easily adjust the PhazeLock 23° Gel Phase Pack to match the conditions. Cool or freeze it before shipping in hot weather, or warm it gently in a room or water bath before sending a package during winter. For moderate climates, simply condition it at room temperature. With proper insulation, each pack maintains a stable 71°F–79°F range for up to 24 hours or longer.
Flexible Pairing for Extra Control
When you need more temperature protection, pair your PhazeLock 23° Gel Phase Pack with other tools:
-
In cold weather, use a UniHeat Shipping Warmer to add gentle heat and prevent chilling.
-
In hot weather, combine it with ice packs or frozen gels to delay warming and extend cooling time.
Before shipping, always check your local forecast to plan for the right combination.
