40-Hour Heat Pack – Reliable Warmth for Short Transit

The 40-hour heat pack from Inter Fresh offers a dependable warming solution for shipments that face cold conditions over shorter transit times. Designed for regional deliveries and quick international routes, this heat pack protects temperature-sensitive products by maintaining a controlled internal temperature.

How It Works

Each pouch contains a natural mix of iron powder and carbon that activates upon exposure to air, generating steady heat for up to 40 hours. The pack starts soft and gradually firms up as the warming cycle completes — simple, safe, and effective.
