Observe whether the hamburger carton is tin foil. If it is tin foil, it must not be heated, because it will melt after heating and then enter the food, which is very harmful to the human body.

Observe whether the hamburger cartons in contact with food are patterned, and try not to use patterned hamburger cartons for heating, because the color will dissolve in high temperature and enter the food, which is also very harmful to the human body.

Hamburger cartons are paper products. Placing them in the microwave oven for a long time will cause spontaneous combustion, which may lead to the explosion of the microwave oven in severe cases. Do not heat hamburgers with hamburger cartons in the microwave oven. Use special containers for microwave ovens, high-quality porcelain and glassware as containers for heating food.

Extended data:

The following foods cannot enter the microwave oven.

1. Don't heat the meat half-cooked. Because bacteria will still grow in half-cooked food, because the time is short, it is impossible to kill all bacteria when heating in the microwave oven for the second time. Frozen meat must be thawed in the microwave before it can be heated to maturity.

2. Avoid freezing the meat thawed in the microwave oven again: Because the meat has been thawed in the microwave oven, the outer layer has actually been heated at a low temperature, and bacteria can reproduce at this temperature. Although freezing can prevent bacteria from multiplying, it can't kill living bacteria. Meat that has been thawed in the microwave oven must be heated until it is completely cooked if it is frozen in the refrigerator again.

3. Turn off the power first, and then open the door to cool down after the fire is extinguished.

4. Avoid overtime heating: If food is thawed or heated in the microwave oven, if you forget to take it out, if it takes more than 2 hours, you should throw it away to avoid food poisoning.

5. Avoid using ordinary plastic containers: use special microwave utensils to hold food and put it in the microwave oven for heating. First, hot food will deform plastic containers. Second, ordinary plastics will release toxic substances, pollute food and endanger human health.

6. Avoid using metal utensils: When iron, aluminum, stainless steel, enamel and other utensils are put into the furnace, electric sparks will be generated when the microwave oven is heated, which will not only damage the furnace body but also heat unfamiliar food.

7. Avoid using closed containers: When heating liquid, use wide-mouth containers, because the heat generated by heating food in closed containers is not easy to dissipate, which makes the pressure in the containers too high and easily leads to blasting accidents. Even when cooking food with shells, you should pierce the shells with needles or chopsticks in advance to avoid bursting, splashing and polluting the furnace wall after heating, or splashing and injuring people.
