The invention discloses a blank structure for forming a sealing strip shaped like a Chinese character 'mu'. The blank structure comprises the sealing strip shaped like the Chinese character 'mu' and composed of two long strips and two short strips. According to the blank structure for forming the sealing strip shaped like the Chinese character 'mu', the width of a blank is 3A, and the length of the blank is h; a left discontinuous longitudinal tangent line and a right discontinuous longitudinal tangent line are arranged on the blank and divide the blank into three longitudinal strips , wherein the width of each longitudinal strip is A; the left discontinuous tangent line is formed by a tangent line 1-1, a tangent line 1-2, a tangent line 1-3 and a tangent line 1-4; the right discontinuous tangent line is formed by a tangent line 2-1, a tangent line 2-2, a tangent line 2-3 and a tangent line 2-4; three strip-shaped openings 5,6 and 7 are formed in a middle strip 3 between the two discontinuous tangent lines, a
