Product Description

The UniHeat 72 Hour Shipping Warmer – 3 Pack is a smart choice for smaller shipping volumes, trial runs, or backup supplies during cold snaps. Each jumbo warmer delivers a gentle, consistent heat source for up to three days, helping protect reptiles, tropical plants, aquarium fish/corals, invertebrates, and other temperature-sensitive items in transit.

Activation is simple: open the wrapper, introduce air, and allow 15–30 minutes for the warmer to ramp up before placing it inside an insulated shipper with modest ventilation. As oxygen-activated heat packs, UniHeat warmers are a go-to solution for cold weather shipping supplies, providing dependable performance for 2–3 day routes.

Choose the 3-pack when you need just enough on hand—perfect for seasonal plant drops, small reptile shipments, or occasional aquatics/insect orders—without committing to a bulk case.

FAQs

Is a single 72-hour warmer enough for a small box?

Often yes. One warmer is typically sufficient for a compact, insulated shipper in mild-to-cold conditions. For larger boxes, extreme cold, or higher heat demand, use two and ensure adequate airflow.

How long should I pre-activate the pack?

Allow 15–30 minutes after opening to reach a steady output. Gently shake to introduce air, and avoid smothering the pack once placed.

Do I need ventilation holes in the shipper?

Yes. These warmers require oxygen. Provide small ventilation holes or an air gap so the pack maintains consistent heat during transit.

Can I use these for reptiles, plants, fish, corals, and insects?

Yes. They are commonly used across live reptile shipping, tropical plant shipping, aquatics (fish/corals), and insect orders to reduce cold stress.

How should I store unused warmers?

Keep sealed in a cool, dry place until needed. Do not open the wrapper or expose the pack to air before use to preserve shelf life.

What if my route is shorter or longer than 72 hours?

For overnight or 1–2 day routes, many shippers use 40-hour warmers. For longer routes or harsher winters, 96-hour warmers may be a better fit.
