1. Ordinary Meal Preparation Containers cannot be put into microwave ovens and ovens, because plastics at high temperatures will produce harmful substances to the human body. If you often use the microwave oven for cooking, it is best to use a plastic lunch box made of polycarbonate (PC) material; If you use a high temperature of about 70 degrees to continuously sterilize and wash, please do not exceed 20~30 minutes, the ordinary dishwasher high heat part is at the bottom, relatively speaking, the upper part is subject to indirect heat transfer, so it is better to clean it in the upper part of the dishwasher. Plastic products made of polypropylene are also heat-resistant and temperature-resistant, but if heated for a long time, the product will deform and stretch. Therefore, if you want to use it immediately after cleaning, please soak the plastic lunch box in cold water before use, which is a good way to prevent deformation. In addition, tempered glass plastic lunch boxes may self-explode when they encounter extreme cold and heat.
2. Different foods have different storage times, do not rely solely on the sealing ability of plastic lunch boxes, should be eaten as soon as possible. P.P (polypropylene) plastic lunch box, when used in the microwave, can be heated for a short time, however, it cannot be used as a cooking container used in the microwave. (When thawing for a short time, do not take more than 3 minutes.) ）
3. When putting in the microwave oven, you must first loosen the lid attachment device before use. If the lid is locked and used, the plastic lunch box will deform or burst due to pressure. When used in the microwave oven, if there is more oil and sugar in the food, the plastic lunch box will be deformed when the temperature rises rapidly.
4. When cleaning the plastic lunch box, use a relatively soft sponge, do not use a hard brush cloth to avoid scratches and discolor the plastic lunch box. When cleaning the silicone liner between the lid and the container, do not pull too hard as it will break or lengthen.
5. Hot food will expand the air and reduce the sealing performance of the plastic lunch box, so it should be stored after the food becomes cool. The bubble of carbonated drinks (soft drinks, cola, etc.) will lose the sealing ability of the plastic lunch box, so please do not store it in the plastic lunch box.
