ABSTRACT OF THE DISCLOSURE A tape reel 12 includes a cylindrical hub 28 having a cylindrical tape winding surface 30, an upper flange 32 and a lower flange 34. Windows 62 are formed in at least one flange 32, 34 to permit air to escape from between adjacent winds of tape 14 during winding of the tape 14 on the reel 12. The perpendicular distance between the upper flange 32 and the lower flange 34 is greater than the width of the tape 14 to be wound on the reel 12 by a maximum of 6.1%. This distance can taper from the inner diameter to the outer diameter by a maximum of 2.9% of the tape width or can be constant.
