Abstract
A wafer shipping box for carrying a number of wafers is provided. The wafer shipping box includes a main body, a cover and a sealing element. The cover can join up with the main body to seal off wafers inside the wafer shipping box. A vent hole is set up on either the body or the cover. The sealing element is used to seal or open the vent hole. Through the sealing element, the vent hole can be sealed so that micro-particles and corrosive gases are prevented from contaminating the wafers and the interior of the wafer box during shipment.
