Plastic containers should not be placed in microwave ovens and ovens, as plastic can produce harmful substances to the human body at high temperatures.
1. Plastic containers should not be placed in microwave ovens and ovens, as plastic can produce harmful substances to the human body at high temperatures. If you frequently use a microwave oven for cooking, choose a polycarbonate (PC) preservation box; If using a high temperature of around 70 degrees Celsius for continuous sterilization and washing, please do not exceed 20-30 minutes. The high heat part of a regular dishwasher is at the bottom, while the upper part is indirectly heat transferred. Therefore, it is better to clean it on the top of the dishwasher. Although plastic products made of polypropylene have high heat resistance, if heated for a long time, the product will deform and elongate. Therefore, if you need to use it immediately after cleaning, please soak the freshness box in cold water before use. This is a good way to prevent deformation. In addition, tempered glass preservation boxes may self destruct when exposed to extreme cold or heat.
2. Different foods have different storage times, so don't rely solely on the sealing ability of the freshness box. You should consume them as soon as possible. P. P (polypropylene) preservation box can be heated for a short period of time when used in a microwave, but it cannot be used as a cooking container in a microwave. (When performing short-term heating and thawing, do not exceed 3 minutes.)
3. When putting it into the microwave oven, the box cover joint device must be loosened before use. If used after locking the lid, the fresh-keeping box may deform or burst due to pressure. When used in a microwave oven, if there is a high amount of oil and sugar in the food, the rapid rise in temperature can cause the freshness box to deform.
4. When cleaning the fresh-keeping box, use a relatively soft sponge and do not use a hard brush cloth to avoid scratching and discoloration of the fresh-keeping box. When cleaning the silicone liner between the box cover and the container, please do not apply excessive force, as it may break or elongate.
