When traditional non-woven fabric masks were dominant, Beihao kept looking for a lighter, thinner, softer, and even invisible mask, until 2008, the world’s first “Invisible Mask” was created in Beihao. After two years of global search and research, Beihao finally found one thin and invisible, soft and fitting film material, which was totally unconventional compared to the traditional non-woven masks that resemble rough and thick white masks. Beihao has led on the industry’s innovation road and now the age of the invisible mask has come.
