Heatpacks
While Inter Fresh is known for cooling solutions, we also offer specialized heat packs that provide controlled warming for temperature-sensitive shipments. Our heat packs are essential for protecting products that require protection from cold temperatures during transit, particularly in winter months or when shipping to cold climate regions.
How our heat packs work
Our heat packs consist of small pouches containing iron powder and carbon that react with oxygen and moisture in the air to generate consistent heat. Once activated, they provide reliable warmth for the duration of their rated period. Unlike cooling elements that start hard and become soft, heat packs begin soft and gradually harden as they complete their warming cycle.
Available duration options
We offer heat packs in three duration options to match your specific shipping requirements:
- 40-Hour Heat Packs: Ideal for shorter transit times and regional deliveries
- 72-Hour Heat Packs: Perfect for standard international shipments
- 110-Hour Heat Packs: Designed for extended shipping times or challenging routes
The duration can be precisely managed based on the volume of the pack, allowing us to tailor solutions to your specific needs.
Primary applications
Plants and horticulture
Heat packs are crucial for shipping live plants during winter months, especially to northern regions where temperatures can drop to -10°C or below. By maintaining temperatures above 10°C within the packaging, heat packs prevent frost damage that could cause plants to deteriorate days after arrival.
Live fish and reptiles
For cold-blooded animals like tropical fish and reptiles, maintaining proper temperature is vital for survival. When shipping these temperature-sensitive creatures, our heat packs help maintain their water or environment at appropriate temperatures (around 30°C for many tropical species).
Benefits of Inter Fresh heat packs
