What are the types of plastic tableware?

1. Polystyrene (PS), polymerized by styrene, is often used as a bowl of instant noodle boxes and fast food boxes. It is heat-resistant and cold-resistant, but too high a temperature will release harmful substances, so do not put bowls of instant noodles into the microwave to heat, and try not to use it to hold hot food, and at the same time, it should not contain strong acidity such as juice and strong acid. Alkaline substances, otherwise styrene and auxiliary materials will be released.


2. Polycarbonate (PC) is synthesized using bisphenol A and diphenyl carbonate as raw materials. It has excellent impact toughness, mechanical strength, and transparency, so it is known as "transparent metal". Commonly used to make water bottles, drinking cups, milk bottles, etc. In the process of making PC, the raw material bisphenol A should completely become a structural component of the plastic and should not be released during use, but in fact it is often not possible. There will be a small part of bisphenol A that cannot be completely converted into the plastic. Is released into food. Bisphenol A is an endocrine disruptor and is particularly harmful to developing fetuses and children. It may cause miscarriage, congenital mental retardation, and mental retardation of infants and young children.

It is a thermosetting plastic and is often used to make bowls, dishes, chopsticks, spoons and other tableware. It is made of melamine and formaldehyde resin as main raw materials, adding appropriate amount of cellulose fillers and colorants and other auxiliary materials. Its appearance and feel are like porcelain, acid and alkali resistance, surface hardness and impact resistance are relatively high, and it has a long service life. It can be cleaned and disinfected in a dishwasher below 120°C. Tableware of the same size and thickness, melamine tableware is lighter than porcelain tableware, but not as easily broken as porcelain, so it is especially popular with parents of infants and young children.
