Uni heat pack 40 hour

Provide extended warmth for live shipments with the Uni heat pack 40 hour, an air-activated shipping warmer made for the longest transits.

• Duration: Delivers 40 or more hours of continuous warmth, ideal for longer or potentially delayed shipments.
• Activation: Air-activated, with no shaking or kneading required. Open the wrapper to expose it to air and allow around 30 to 45 minutes for it to reach full heat before packing.
• Performance: Releases steady, gentle heat with a gradual build-up designed for the enclosed environment of an insulated shipping box, avoiding the heat spikes that can stress live cargo.
• Usage: Designed for safely transporting live insects, reptiles, amphibians, fish, corals, and plants. Wrap it in paper to diffuse the heat, keep it from direct contact with animals or plants, and make sure the box has some ventilation.
• Contents: Non-toxic, biodegradable inner components containing iron powder, water, vermiculite, activated carbon, and salt. Single-use.
