Most high-quality isothermal boxes maintain safe temperatures for 4 to 6 hours. Longer retention depends on pre-heating the box and the ambient temperature outside.
Lunch boxes are compact, portable, and designed for individual meals. Catering carriers are larger, often stackable, and built to hold multiple full-size pans for professional use.
