Product Description

The UniHeat 96 Hour Mega Shipping Warmer – 3 Pack delivers gentle, consistent heat for up to four days—perfect for long-distance or weather-impacted transit windows. These mega heat packs help protect reptiles, tropical plants, aquarium fish/corals, invertebrates, and other temperature-sensitive goods when standard 72-hour warmers may fall short.

To activate, open the wrapper, shake lightly to introduce oxygen, and allow 20–30 minutes for the pack to ramp up before loading into an insulated shipper with small ventilation holes. As oxygen-activated heat packs, UniHeat warmers are a proven part of cold weather shipping supplies for reliable 3–4 day performance.

Choose this 96-hour format for long-haul routes, weekend overlaps, or harsh winter conditions where stable output over multiple days is critical.

FAQs

When should I choose 96-hour over 72-hour warmers?

Use 96-hour for shipments expected to be in transit 3–4 days, for harsh winter temps, or where delays are more likely. For typical 2–3 day routes in mild conditions, 72-hour can suffice.

How long do I pre-activate before packing?

Allow 20–30 minutes after opening so the warmer reaches a steady output. Do not smother—ensure modest airflow inside the shipper.

Do these need ventilation holes?

Yes. They require oxygen to function. Provide small ventilation holes or an air gap to maintain consistent heat during transit.

How many 96-hour warmers per box?

For compact, well-insulated shippers, one is often sufficient. Use two+ for larger volumes, extreme cold, or higher heat demand—space them apart for airflow.

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

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

Storage and shelf life?

Keep sealed in a cool, dry place until use and follow the printed best-by date. Do not expose to air before activation.
