The invention discloses a cabin cover sealing strip which comprises a polytetrafluoroethylene sponge core and a wrapper, wherein the wrapper coats the outer side of the sponge core, and comprises a first wrapper, second wrappers and a third wrapper; the first wrapper coats the top surface of the sponge core and is horizontally arranged; the second wrappers coat two opposite sides of the sponge core and are arranged along the vertical direction; the third wrapper coats the bottom surface of the sponge core and is set to be of an arc form; each second wrapper comprises a first upper wrapper with a first thickness and a lower wrapper with a second thickness; the lower wrapper is connected with the bottom end of the upper wrapper; and the first thickness is greater than the second thickness. A polytetrafluoroethylene seal material is adopted; polytetrafluoroethylene has excellent chemical stability and low friction coefficient; and especially the physical and mechanical properties of filling polytetrafluoroethylene are further improved on the basis of keeping the original excellent properties due to the addition of a filling reinforced material, so that the tensile strength of the product greatly exceeds the conventional index requirement of not smaller than 10MPa, and reaches about 13.4MPa.
