EcoTherm Phase Change Shipping Packs are designed to help keep temperatures stable during shipping. The product has a high specific heat—it takes a lot of energy for it to change temperature, and turns from solid to liquid at 74°F. EcoTherm Shipping Packs will help buffer temps when using ice or heat packs, and help avoid extreme temperature swings during shipping.

Each pack measures approximately 4 x 6.5 x 1 inch.

How to Use:

IN COLD WEATHER: Ship in liquid state (soak in water warmer than 74F) with heat pack

IN WARM WEATHER: Ship in solid state (keep below 74F) with ice pack

Warnings/Caution:

TO DISPOSE: Simply dispose of the liquid as you would food waste - it's organic and even compostable! The plastic envelope can be recycled.
