How It Works

Self-heating mechanism diagram
  1. 1. Add a small amount of water to the heater compartment.
  2. 2. The water reacts with the chemical heater (typically calcium oxide or magnesium iron alloy).
  3. 3. Heat is generated within 30 seconds, reaching 80–100°C.
  4. 4. The food or drink is heated from below in 3–5 minutes.
  5. 5. Enjoy your hot meal—no flame, no electricity needed.

Safe for outdoor, military, emergency, and commercial use.

Frequently Asked Questions

How does the self-heating pack work?

The pack uses a water-activated chemical reaction (typically between calcium oxide and water) to generate heat. Simply add water to the heater base, place the food container on top, and wait 3–5 minutes.

Is it safe to use?

Yes. Our packs are ISO9001 certified and made with food-safe materials. The reaction is flameless and contained. Always follow instructions and avoid direct contact with the heater after activation.

Can I customize the packaging?

Absolutely. We offer full OEM/ODM services including custom sizes, branding, packaging design, and heater capacity adjustments.

What products can be heated?

Ideal for instant coffee, noodles, rice, soups, stews, and ready-to-eat meals. The system is adaptable to various food types and container designs.
