The plastic tableware is in tatters. It's time to change it.
Plastic products also have shelf life. After expiration, the plastic will age, change color and become brittle. If the used plastic box is found to be yellow or no longer transparent, it should be replaced as soon as possible. Therefore, there is always someone on the Internet who says, "Plastic lunch boxes will be uneven if they are used for a long time. If you lose it, you will be eaten. " I can't believe it ~ Therefore, consumers must pay attention to the shelf life of plastic products. At the same time, aging plastics may release substances harmful to human body. As for the "life" of a plastic lunch box, it depends on personal use and cleaning methods. The shelf life of most plastic products is generally about three to five years. If you use it frequently, it is best to replace it once every one to two years.

You can't put these foods in plastic lunch boxes.
Bubbles in carbonated drinks (soda, cola, etc.). ) will make the sealing ability of plastic lunch boxes lose, and foamed food, fermented food and hot food will make the sealing performance of plastic lunch boxes decline. Please try to avoid storing such food in plastic lunch boxes.
When used in a microwave oven, if the food contains more oil and sugar, the plastic lunch box will be deformed when the temperature rises rapidly. Therefore, it is best to use a special box for microwave oven to heat the above food.

Is it poisonous to heat plastic tableware?
We need to know what will be added to the plastic lunch box first. Yes, there is a substance called plasticizer. Plasticizers can enhance the flexibility of plastics and make them easier to process and plasticity. They have been widely used in industry, so plastic products are easy to release plasticizers after heating. At present, the commonly used plasticizers in the market mainly include DBP, DEHP, DINP and DIDP.
Every plastic has a heat resistance limit. Among the food materials, the most heat-resistant is polypropylene (PP), which can withstand 140℃, followed by polyethylene (PE), which can withstand 1 10℃, and polystyrene (PS), which can only withstand 90℃. At present, plastic lunch boxes used in microwave ovens are mainly made of PP or PE. If the temperature exceeds their heat resistance limit, plasticizers may be released, so it is necessary to avoid heating plastic lunch boxes at high temperature for a long time to heat food.
You should use plastic tableware like this!
It is best to heat only porridge and soup filled with water in plastic lunch boxes. Meat food, including high-sugar food, etc. It is best to use porcelain or glass containers for microwave heating.

If plasticizers are used in food containers and food packaging materials, they shall not come into contact with oily food and infant food.
Even the plastic tableware of microwave oven that has passed the standard test is only recommended to be used under the condition of short-term heating below 700W, and can only be used under stricter conditions, unless the product is marked for cooking or has obtained other higher international certification. 700W is roughly equivalent to the mid-range firepower of a microwave oven, and the general manual has the output power of each firepower. Short-term heating means heating for 2 ~ 3 minutes, and cannot be used for cooking cooked food.
Babies who like to use plastic tableware must pay attention to the use specifications! The intelligence army hopes that everyone will be healthy and let the intelligence army rest assured ~
