What kind of lunch box is the best for microwave ovens?

1. glassware: glassware made of borosilicate glass, microcrystalline glass and titanium oxide crystal glass is suitable for long-term use in microwave ovens because of its good microwave penetration, stable physical and chemical properties and high temperature resistance (up to 500 degrees Celsius or even 1000 degrees Celsius). Glasses, baby bottles and baby bottles made of ordinary glass are only suitable for heating in the microwave oven for a short time, about 3 minutes. If the heating time is long, it is easy to crack. Carved glass, tempered glass and crystal glass products will burst when cooking oily food due to uneven thickness of materials, and are not suitable for use in microwave ovens.

2. Ceramic utensils: there are heat-resistant ceramics and ordinary ceramics. Pots, plates and other utensils made of heat-resistant ceramics are suitable for long-term use in microwave ovens, while ordinary ceramic utensils can only be used for short-term heating. In particular, it should be reminded that ceramic utensils containing gold and silver wires will generate sparks when used in microwave ovens, so they are not suitable for use.

3. Plastic utensils: various utensils made of polypropylene, polypropylene resin, composite polypropylene and polysulfone. , can withstand the temperature above 120 degrees Celsius, and can be used for microwave heating. The container made of PET resin and polyester material can withstand the temperature above 220 degrees Celsius and can be used for barbecue. Plastic wrap also belongs to plastic products: one is common plastic wrap, which can be used when heating vegetables; The other is special plastic wrap for microwave oven, which can be used to heat meat, poultry and sugar food. As for heat-resistant polyethylene, styrene, phenol, melamine and other utensils, don't use them in the microwave oven, because these materials absorb microwaves and will melt when heated, and some will release toxins and odors, which are harmful to human health.

4. Metal utensils: various utensils made of metal materials such as aluminum, stainless steel and enamel. Because the microwave can't penetrate and the food inside can't be heated, it is not suitable for use in the microwave oven.

5. Wood, paper and other utensils: In the wet state, these utensils can be used in the microwave oven for a short time. But if it takes a long time, the drying of the utensils will lead to overheating. These painted utensils are forbidden to be used in the microwave oven, because there is benzene in the paint, which will be emitted by microwave heating and pollute the food.
