Product Description

The UniHeat 40 Hour Multi-Purpose Heat Pack – 10 Pack delivers gentle, consistent warmth for short to mid-length transit windows. Perfect for overnight and two-day deliveries, these oxygen-activated heat packs help protect reptiles, tropical plants, aquarium livestock & corals, invertebrates, and other temperature-sensitive goods during cooler weather.

To activate, open the wrapper, shake lightly to introduce oxygen, and allow 15–30 minutes for the pack to ramp up before loading into an insulated shipper with modest ventilation. The 10-count bundle is a step up from trial packs—great for weekly shipping without jumping to a bulk case.

FAQs

When should I choose 40-hour vs. 72- or 96-hour warmers?

Use 40-hour for overnight and 1–2 day routes in mild to cold weather. Choose 72-hour for typical 2–3 day transits and 96-hour for 3–4 day or harsh winter routes.

How long do I pre-activate the pack?

Allow 15–30 minutes after opening to reach steady output. Don’t smother the pack—maintain a small air gap for oxygen flow.

Do these require ventilation holes?

Yes. They are oxygen-activated. Provide small ventilation holes or an internal air gap so the pack maintains consistent heat during transit.

How many 40-hour warmers per box?

For compact, insulated shippers, one is often enough. Use two+ for larger volumes, colder routes, or higher heat demand—space warmers apart to ensure airflow.

Are these safe for reptiles, plants, fish, corals, and insects?

Yes—when used properly. Avoid direct contact with animals or foliage. Validate your packing method with a thermometer before live or high-value shipments.

How should I store the 10-pack?

Keep sealed in a cool, dry, low-humidity environment. Follow the printed best-by date and avoid exposing unused packs to air until ready to ship.
