🌡️ Exp date March 2024 but works perfectly - 96-Hour UniHeat Shipping Warmer
Keep your plants cosy on their journey! These long-lasting 96-hour heat packs are perfect for protecting tropicals and cold-sensitive plants during transit. Personal experience in have added to a box with some brown paper between it and the plant, simply leave and it will activate itself making the box toasty warm. As hand warmers I have popped this in a jacket and an hour or so later the heat is just what you need in the cold winter weather.
✨ Why they’re ideal for plant shipping:
Provides up to 96 hours of steady, reliable warmth
Helps prevent cold shock during delivery
Simple to activate and plant-safe
Great for winter orders or chilly weather
Add one to your parcel for peace of mind and happy, warm plants all the way to their new home. 🌱💚
A 96-hour heat pack (like UniHeat) is a disposable warmer for shipping temperature-sensitive items (fish, plants, reptiles, etc.), activated by air, providing steady warmth for about 4 days, ideal for express shipping but may stop working in freezing temperatures. They contain iron powder, water, salt, charcoal, and vermiculite, generating heat through oxidation, and are environmentally friendly. Key info includes activation upon opening, slow temperature decay (around 100°F/38°C for most of its life), and that they don't guarantee against cold damage in extreme cold (below 32°F/0°C).
How They Work
Activation: Open the sealed package to expose the contents (iron powder, water, activated carbon, salt, vermiculite) to air, starting the oxidation process.
Heat Generation: The iron oxidizes (rusts), releasing heat.
Temperature Profile: They heat up quickly (peak in ~9 hrs), then maintain a steady, lower temperature (around 100°F/38°C) for most of their 96-hour life, designed to avoid overheating delicate cargo.
Key Features & Uses
Duration: Provides consistent heat for approximately 96 hours (4 days).
Applications: Transporting tropical fish, corals, reptiles, plants, flowers, and even some chemicals or medical supplies.
Environmental: Biodegradable and disposable with regular trash.
Reliability: Used by professionals for air, sea, and road transport.
Important Considerations
Activation Time: Takes about an hour to start warming effectively.
Freezing Temperatures: Heat packs can stop working if the ambient temperature inside the box drops below 32°F (0°C).
Shipping Speed: Best for priority/express shipments; not ideal for standard mail that takes longer.
Usage: Use with insulated boxes for best results; follow seller instructions when ordering with plants.
