Description
The UniHeat 72 hour heat pack (shipping warmers) is a popular heat source for those who are shipping reptiles, amphibians, insects, invertebrates, fish, plants and other perishable items.
The 72 hour heat pack will activate in under an hour and reach its peak temperature of 115°F (46°C) in approximately 4 hours. The heat pack will then gradually drop to 100°F (38°C) for remainder of its operational life. One 72 hour heat pack will increase the temperature of a 1cu. ft. insulated box by approximately 15 degrees, for every additional heat pack that you use the temperature will raise an additional 10 degrees. Ideally the 72 hour heat pack is used for priority 2 day shipping, as they are not recommended for 3+ days shipping. Please order our 96 hour heat packs for shipments that require 3 day transit times.
