Abstract
Technological advances have offered many conveniences in various areas of life. Food packaging is also increasingly innovative to meet the dynamic needs of human life. Packaging innovation also extends to practical aspects of use, one of which is the need for self-heating food packaging. Therefore, this research focuses on making heaters for self-heating packaging that work based on non-toxic exothermic reactions using materials commonly used in society. The heater is made using a mixture of CaO, NaOH and Mg with a composition of 1:1:0.5. The heat released reaches 70 oC if measured directly in chemicals. In Al-sachet packaging, the heat is measured at less than 50 oC due to heat transfer problems in aluminum. However, in paper bag packaging, the heat released in water can reach 60 oC for a duration of 15 minutes. The downside to using paper bags is the transfer of chemicals from the bag to the water and then to the food. Therefore, appropriate heating package design is essential to reduce potential hazards.
