Can disposable tableware be microwaved

Whether most disposable tableware will melt or not, it is best not to heat it. Some disposable lunch boxes can be heated. Although there are disposable lunch boxes made purely for heating, it is difficult for us to judge whether they can be heated. Therefore, I personally think that as long as there is no label on the lunch box that can be heated, it defaults to non-heating.

Disposable lunch boxes can only be used for light meals and cannot be used twice. The material of disposable lunch boxes is polystyrene, which is easy to melt in high temperature environment. It will deform at above 70°C. It is easy to be corroded by strong acids and alkalis and is not resistant to grease. It is easy to change color after being irradiated by ultraviolet rays.

The safety of foamed plastic tableware is related to the pH of the food, whether it contains oil, and the temperature. According to national regulations, foamed plastic lunch boxes should be used below 70°C, so it is best to use special microwave heating appliances for safety reasons.

How to choose tableware

1. Ceramic tableware

Ceramics can be said to be one of the best materials, but in order to make ceramic tableware look more beautiful, some unscrupulous merchants choose some unsafe materials when coloring them. These materials are easy to precipitate after being heated and cause harm to the human body.

2. Stainless steel cutlery

Stainless steel tableware has gradually become a big craze for people to buy. Stainless steel tableware is good, but there are certain taboos in its use. We need to pay attention to it all the time.

3. Glass tableware

It is clean and hygienic and does not contain toxic substances. But glass tableware can also "mouldy" sometimes. This is because the glass is corroded by water for a long time, and the sodium silicate in the glass reacts with the carbon dioxide in the air to form white carbonic acid crystals, which are harmful to human health, so it can be removed with alkaline detergents during use.

4. Plastic tableware

Currently considered safe plastic meals include polyethylene, polystyrene, polypropylene plastic products and so on. When purchasing and using, you must pay attention to confirm which type of plastic the plastic belongs to. Recycled plastics, plastics with dark pigments, and non-food plastics must not be used for holding or packaging food, otherwise, it may be harmful to the human body. Cause poisoning.
