PS is often an alternative to PP and LDPE. PS is more cost-efficient than the two, but has slightly less quality characteristics. A PS drinking cup tears more easily than one made of PE and with very hot coffee, a PS machine cup can shrink a bit, you probably know it, PP does not suffer from that.
PS is highly insulating and is widely used in the packaging world: cutlery, plates, dishes, trays… especially the real mass items with a lot of competition, which therefore have to be produced cheaply, are often made from PS.
