InstaHot generates the heat energy through the exothermic chemical reaction of metal powder and oxides in the presence of water. The chemicals go through multiple levels of processing to arrive to desired formulation. Once processed the proprietary chemicals are packed in a heater pouch. The material for the heater pouch is designed to be water permeable. The packed chemicals upon coming in contact with water initiate an exothermic reaction. This exothermic reaction is the heat source for InstaHot. It is also designed keeping in mind the safety of the food packet. The surface temperature of the InstaHot heater pouch does not go beyond 95℃ to ensure the safety of the food packet.


  • InstaHot provides a temperature rise of 45℃ for a 300gm pouch under standard conditions
  • InstaHot has been tested under different climate conditions
  • Tested as per RoHS 2011/65/EU for heavy metals and EU/10/2011 for chemical migration analysis


The product generates heat energy through an exothermic reaction between metal powder and water. The heat energy thus generated heats the surface of the food pouch and this heat is transferred to the packed food.

The reaction will not cause any harm to the packaging material or the food pouch. InstaHot heats the food pouch at temperatures lesser than 95 °C.

All the chemicals are safe and non-toxic..

The product has been tested multiple times for migration analysis. It is a ROHS 2011/65/EU compliant product.

No, raw foods cannot be put inside the bag directly. We recommend using a food grade microwave safe zip pouch to heat home cooked or raw food.

Yes, you can use a zip bag to heat home cooked food. We recommend using a food grade microwave safe zip pouch to heat home cooked food.

Yes, once used heater can been disposed in any normal dustbin.

All the different types of food pouches are available at all major retail chains, online grocery stores, all major e-commerce websites and respective websites of food manufacturers.
