72 Hour Heat Pack Uniheat

Sometimes, your package needs extra protection—especially in winter or when crossing multiple regions. The UniHeat 72 Hour Heat Pack provides up to three full days of controlled warmth, making it ideal for live animals, tropical plants, or perishables that face long journeys.

Ideal for Cross-Country Shipping

Thanks to its extended activation time and balanced heat output, this 72-hour version minimizes temperature fluctuation during long transit. It’s a great step up from our 60 Hour Heat Pack if your shipping timeline runs past two days.

Growers, pet suppliers, and eco-logistics companies love this version because it adds a safety buffer while keeping operating costs reasonable.

Upgrade Options

For even longer protection, check out the 96 Hour Heat Pack—our longest-lasting solution for extended shipments.
For shorter deliveries, switch to the 40 Hour Heat Pack — compact, efficient, and perfect for next-day shipping.

No matter the distance, UniHeat keeps your cargo safe, warm, and ready to thrive.
