With the acceleration of the rhythm of life, insulated lunch boxes have become one of the popular options for taking and storing food. The main function of an insulated lunch box is to maintain the temperature of food hot or cold and it can effectively prolong the temperature retention time. But here comes a question: Can an insulated lunch box be put in the refrigerator? Let’s discuss it now.
The function and material of an insulated lunch box
Normally, insulated lunch boxes are made from high-density foam material, aluminum foil, plastic, or stainless steel. Their core role and function are basically to reduce any loss or absorption of heat through the insulation layer for maintaining a stable temperature internally. This design fits perfectly in keeping food warm or cold for a short length of time.
The feasibility of putting it in the refrigerator
Insulated lunch boxes can be put in the refrigerator, but the following points should be noted:
The insulation function will not be destroyed
Refrigeration temperature doesn’t destroy the insulation performance of an insulated lunch box, so putting it into a refrigerator won’t harm its insulation performance. However, as there is insulation material with the box, it makes the speed of cold air enter into the box reduce. Thus, the refrigerating effect may not be too ideal compared with putting it in the fridge directly.
Choose the right material
If the insulated lunch box is made of high-quality plastic or stainless steel, then it can stand the low-temperature environment in the refrigerator without a problem. However, if the insulation is made of some special foam, long exposure to low temperatures may reduce its service life. It is recommended to check at the time of purchase to confirm whether the product description shows suitability for refrigeration.
Pay attention to hygiene and odor issues
There are all types of foods in the refrigerator, and smells could leak into the insulated lunch box. Therefore, it is better to seal the lunch box with a sealed lid or even wrap it with plastic in order not to let the outside air go in before putting the lunch box into the refrigerator, for the sake of prevention from contamination of odors.
Better refrigeration suggestions
If you often need to refrigerate food in lunch boxes, here are some tips:
- Refrigerate food directly: You don’t have to put the whole insulated lunch box in the refrigerator but can first put the food that needs refrigeration into an ordinary fresh-keeping box and then refrigerate it.
- Pre-cooling of the lunch box: When carrying cold food, to extend the cold-keeping time, an insulated lunch box could be placed in the refrigerator for cooling the night before.
- Use with an ice bag: An ice bag can be placed in an insulated lunch box to keep the food cold and avoid putting the lunch box in the fridge directly.
Summary
Although insulated lunch boxes can be put into refrigerators, that’s not a very good option. If it is only for refrigerating food, ordinary fresh-keeping boxes or even glass containers would do a much better job. If one insists on putting some refrigerated foods in an insulated lunch box, they must first check if the material of this insulated lunch box is resistant to refrigeration and pay attention to good sealing for the sake of food freshness and cleanness.
