⒈Ordinary plastic plastic lunch boxes can not be put into microwave ovens and ovens, because plastics will produce harmful substances to the human body at high temperatures. If you often use a microwave oven for cooking, it is best to choose a plastic lunch box made of polycarbonate (PC).
If you use a high temperature of about 70 degrees for continuous sterilization and washing, please do not exceed 20-30 minutes. The high-heat part of the ordinary dishwasher is at the bottom, and the upper part is relatively indirect heat transferred, so it is better to put it in the upper part of the dishwasher.
⒉Different foods are kept for different times. Don’t rely solely on the sealing ability of the plastic lunch box. You should eat it as soon as possible. The P.P (polypropylene) plastic lunch box can be heated for a short time when used in a microwave oven, but it cannot be used as a cooking container used in a microwave oven. (When heating and thawing for a short time, the time should not exceed 3 minutes.)
⒊When putting it in the microwave oven, you must loosen the box cover joint device before using it. If the lid is locked and used, the plastic lunch box may deform or burst due to pressure. When used in a microwave oven, if the food contains more oil and sugar, the plastic lunch box will be deformed if the temperature rises rapidly.
