金属薄片
jīn shǔ báo piàn
foil
Taiwan pr. [jin1 shu3 bo2 pian4]
gold (金) + belong (属) + thin (薄) + sheet (片) = metal foil
Each character pulls its weight: 金属 names the material (metallic), 薄 signals thinness (艹 is phonetic context; 溥 gives the sound), and 片 evokes a flat sheet split from something solid, like half a tree trunk. Together they describe a thin, flat piece of metal precisely.
