Self heating bags- these packs are designed to heat food without an external heat source. They are typically used in situations where cooking facilities are not available, such as camping, hiking, or traveling. As long as there is enough water,  the food can be heated to a high temperature in a short time. In these situations self heating bags are very popular and convenient to use.

Features of Self heating bags

Portablity

The self-heating pack itself is compact in design, usually in small individual packages, taking up little space and easily fits into a backpack, bag, or even pocket. Compared with traditional heating tools (such as portable stoves), its weight is negligible and does not add additional carrying burden, making it suitable for short-distance travel, camping, hiking, and other scenarios.

Fast

The core ingredients are aluminium and other metal powder. When the aluminium based heating bags encounter water, it can produce a large number of heat in a short time(typically 5-15 miniutes) as long as you add enough water.

Convenient

They have wide range of application scenarios and can adapt to a variety of needs. Just with enough water, it can not only be used to heat food (such as self-heating rice, hot pot, canned food), but also to keep drinks (coffee, tea) warm. From outdoor activities and long-distance travel to office overtime, it can be used to adapt to the portable heating needs of different scenarios.

 

How to use self heating bags

During the usage process, no complicated steps are required, just follow the instructions to add an appropriate amount of water to quickly start the heating process, and the heating of food and drinks can be completed in a few minutes. No need to prepare fuel and preheat equipment in advance, saving time and operating costs, especially suitable for quick use in emergency situations.

Step 1 Split container

Self-heating food usually consists of three parts: the outer box, the inner tray (for food), and the heating pack. Open the outer box first and take out the inner box and heating pack.

Step 2 Add water to the box

Pour an appropriate amount of cold water (do not use hot water) to the bottom of the outer box (where the heating pack is placed) to avoid overly violent reactions.

Tips: Some products will mark the water level line, just add water according to the line.

Step 3 Place the heating pack and close it tightly

Quickly put the heating pack into the bottom of the outer box filled with water . Immediately place the inner box containing the food into the outer box and close the outer box lid tightly.

Step 4 Wait for the heating to complete

Wainting for a few minutes then the food can be heated. The standing time is according to the product description (usually 5-15 minutes), and when there is no more obvious hot steam, it means that the reaction is basically over.

Notes

The heating pack should not be in direct contact with the food, it should be placed at the bottom of the outer box, and the inner box should be on top (keep isolated from the heating pack).

The amount of water should be strictly according to the product instructions (usually 100-150ml, about half a cup), too much may cause the liquid to spill, and too little may not react adequately.

Be careful not to pinch the heating pack directly with your hands, if the package is damaged, it is forbidden to use it.

Make sure to seal the lid tightly to prevent hot gas and liquid from spilling out.

A large amount of heat will be generated quickly during the heating process, and the temperature of the outer box will rise, so do not touch or move it to avoid burns.

Conclusion

The heating bag is not only convenient, but a highly efficient tool to use. By the internal reaction of water and other components to produce a large amount of heat, it provide a fast and convenient way to haet food.  You can enjoy better life with it. In addition, there are different packages, you can customize it in your own way. If you have any needs, feel free to contact us.
