Precautions for using plastic lunch boxes

Plastic lunch boxes are lighter and easier to carry. Many people who go to work will choose to use them to bring meals. Some people think that plastic lunch boxes are simply containers for food. When buying and using them, they are very casual. In fact, there are many advantages to using disposable lunch boxes. There are few places that need attention. Next, the editor will tell you the precautions for using plastic lunch boxes.

1. Scrub clean before one use.

When the plastic lunch box is used for one time, there will be some plastic smell, so be sure to clean it before using it.

2. Avoid using plastic lunch boxes to heat high-fat foods.

Because the boiling point of oil is very high, it is easy to exceed the bottom line of plastic heat resistance when heated, and oil, sugar and plasticizer are all organic substances that can dissolve in each other, so it is better to avoid using plastic boxes to heat foods that contain a lot of fat and sugar , so as not to produce harmful substances that endanger human health.

3. Choose plastic lunch boxes with good quality and safety signs.

High-quality plastic lunch boxes are relatively hard to pinch, and have complete safety labels, including raw materials, dates, origins, and precautions for use; inferior plastic lunch boxes are soft when pinched, and various information is incomplete. Pay special attention when purchasing .

4. Regularly replace the lunch box.

Plastic lunch boxes are often exposed to heat and sunlight, which can easily damage the plastic molecules and make the plastic fragile and aging. If the plastic box is found to harden, change from transparent to atomized, it should be replaced in time. If you put hot food porridge or put it in a microwave oven, more harmful substances will be released.

5. Microwave the plastic lunch box and open the lid.

Opening the lid and heating can prevent the toxic substances in the lid from being released by heating. At the same time, if the box body also releases toxic substances, opening the lid and heating can release the toxic substances into the air. Therefore, when putting plastic lunch boxes in the microwave oven, try not to cover them.

6. Plastic lunch boxes for microwave heating

When you want to use a microwave oven to heat a plastic lunch box, try to use a plastic lunch box in the microwave oven, and then carefully check how high the temperature of the lunch box is, so that it will be better to use. Otherwise, some heat-labile lunch boxes will release plasticizers and endanger human health when they encounter high temperatures. At present, the more heat-resistant is polypropylene, which can withstand 140°C, followed by polyethylene, which can withstand heat up to 110°C, while polystyrene can only withstand heat up to 90°C, and the heat of a microwave oven can reach above 120°C, so try to choose polypropylene plastic lunch box.
