A wafer transport box (such as a front-opening unified pod, FOSB) is a plastic container with a front-opening structure. It utilizes low outgassing materials and shockproof design to protect wafers from dust, moisture, or vibration during cross-factory transportation.

COP material, with its extremely low metal ion precipitation and ultra-low moisture absorption, can effectively protect wafers from contamination and prevent product defects caused by moisture absorption.
