Plastic tableware has always been loved by many families for its advantages of lightness, beauty, and resistance to breakage. As long as the qualified plastic tableware is used properly, there is no harm. Once you buy inferior quality or use it improperly, the harm is equally huge!
Not all plastics are suitable for tableware. Plastic meals made of polyvinyl chloride are poisonous and endanger human health. Plastic tableware made of raw materials such as polyethylene, polypropylene and melamine are safe. Melamine plastic is a kind of thermosetting plastic. It is made of melamine formaldehyde resin as the main raw material, added with appropriate amount of pulp, cellulose filler and colorant and other auxiliary materials. It is acid and alkali resistant. Now it is mostly used in the market to make children's tableware, also known as Imitation porcelain tableware. Qualified imitation porcelain tableware is safer, as long as it is used correctly, there is no need to worry too much about its harm. However, if the raw material resin is not polymerized well, it is easy for melamine to be incorporated into food. In addition, melamine may decompose to produce cyanide at high temperatures, and may produce harmful substances when heated or placed in a microwave oven.
Therefore, even if you use qualified melamine tableware, do not store acidic, oily, and alkaline foods for a long time, let alone store high-temperature foods or place oily foods in the melamine tableware to heat in a microwave oven.
In order to avoid mistaken selection of imitation porcelain tableware, be sure to look for the QS logo when purchasing, and you can buy it at regular stores and supermarkets. Experts suggest that children should not choose bright-colored imitation porcelain tableware, especially those printed on the inside, and should try to choose light-colored imitation porcelain tableware.
