What Material Is Used For Ps Lid

When we drink hot drinks in winter, we often see a lid on it, and this lid is a Ps lid . The material used for the PS cover is polystyrene.

Styrene monomer is a kind of aromatic hydrocarbon, which is an organic compound formed by replacing one hydrogen atom of ethylene with benzene. Polystyrene resin is a polymer synthesized by styrene monomer through a radical condensation reaction, and it is a kind of plastic that we commonly use. The usually used polystyrene molded products are made of polystyrene resin as the main raw material and processed by corresponding production processes. The advantages of polystyrene are lightweight, high strength, and low cost. At present, it is widely used in food packaging, such as cup lids, plastic water cups, etc. In plastic packaging products, there will be marks with numbers to indicate different plastics. Among them, the number mark code "6" represents polystyrene. If you see a "6" mark on the lid, it means that the lid is made of polystyrene.

And like the Paper cup sleeve , as the name suggests, the raw material should be related to paper, but it will be more wasteful.
