  When you go out to buy hot drinks such as coffee, milk tea, etc., have you paid attention to the symbols on the lid of the cup? There are many cup lids with a triangle symbol with the number 6 written in the middle. This shows that the material of the lid is No. 6 plastic polystyrene, which is what we call the Ps lid .

  There are generally two types of lids for hot drinks on the market: one is a straw type, and the other is a direct-drinking type. The straw type has pre-opened holes for drinking through the straw. The direct-drinking type has a drinking port, and you can drink directly through the lid of the cup. At present, the lids of hot drink cups on the market are mainly made of polypropylene (PP) and polystyrene (PS).

  Polystyrene monomer is a kind of aromatic hydrocarbon, which is an organic compound formed by replacing one hydrogen atom of ethylene with benzene. The raw material for the production of polystyrene, styrene is a toxic and hazardous substance. The tentative maximum allowable daily intake of styrene established by JEFCA is 0.04 mg/kg. For a person weighing 60 kg, the maximum allowable daily intake is 2400 micrograms.

  In addition to cup lids, it is also very common for us to have the Paper cup sleeve when we buy hot drinks.
