Meet UniHeat—the self-activating shipping warmer we trust for winter transit. Tear open the pouch and it begins heating in 10–30 minutes, delivering steady, eco-friendly warmth for 20–120 hours. Lightweight and puncture-resistant, UniHeat is non-toxic, hazmat-exempt (IATA/USPS/UPS/FedEx), and available in adhesive or non-adhesive formats. Perfect for live animals, plants, pharma/biotech, and cold-season e-commerce, it keeps boxes in the safe zone from pickup to delivery.
Pro tip: pair with solid insulation (and, when needed, a PhazePak PCM) and test a mock run with a thermometer for dialed-in results.
