According to statistics, from February to August this year, South Korean mask factories surged from 380 to 1090, and the number of factories nearly tripled in half a year. With the increase of mask manufacturers, the production capacity of masks continues to increase. Recently, the average daily mask production in South Korea has reached 80 to 90 million, which has more than doubled the demand. Due to the oversupply of masks, the price of masks fell rapidly. There are already a large backlog of masks in many factories, involving tens of millions of yuan. At present, mask factories have begun to close down or suspend production one after another.
