Heating packs, also called food-type heating packs

are made of self-heating materials and a combination of non-proof cloth and OPP plastic film. When using it, just remove the OPP plastic film, put it in a heat-resistant box, and use it according to the actual use method.
So what does the heating pack consist of? The heating pack manufacturer takes us through a simple look:

With the continuous improvement of consumption levels and the pace of life, self-heating food has evolved into many types, such as self-heating rice, self-heating hot pot, self-heating fans, self-heating noodles, and self-heating turtles. Powdered and self-heating vegetables and fruits. Heating packs are one of the prerequisites for self-heating.

The heating pack (also called a food heating pack) is made of self-heating materials (main ingredients are calcium hydroxide, sodium bicarbonate, etc.), sealed with non-proof cloth, and then passed through OPP plastic film (overall packaging).

When it needs to be used, first tear off the OPP plastic film, put the hot compress bag into a heat-resistant box, add a certain amount of normal temperature water (no need to boil water), and use the hot compress bag and water to react with the heat generated by releasing radon gas when heating food. The heat is separated from the food by using partitions without direct contact with the food.

The heating pack does not come into direct contact with the food, and this method has been implemented in the defense field for many years. Many troops who need to perform field missions are equipped with hot compresses. The military power provided to the locals is stronger, and many substances are popular in the civilian market. Therefore, it is also possible to prove that heating packs are not harmful to the body shape. Filling: Add quicklime powder, potassium carbonate and water to react flexibly to provide original heat.

Vermicelli, alumina powder, carbon, salt, etc. form a primary battery, which continuously oxidizes and releases heat. The ingredients of the heating parts are mainly mixed with calcined attapulgite, vermicelli, alumina powder, coke powder, salt, lime powder, potassium carbonate, etc., and then heated to increase the temperature of the heated food. When using “self-heating food”, please try to use the heating packaging in strict accordance with the instructions, and be careful to open the open air holes during the heating process so that the self-heating food can heat the food. Prerequisites for controllability. To prevent accidental damage.

The above is the structure of the heating pack. If you have more detailed questions or if you have this aspect in mind or are unclear, please contact us.
