Well, panels are not any different component. Panels are the segments or octagon quilt that are seen outside the balls. Of course, nowadays you will find some other shapes besides octagon. FIFA official balls usually contain 32 panels. But nowadays you will also find 26, 18, 14, 8 or even 6 panels with different shapes and designs from those of conventional balls.

Latex bladders are one of the best materials when it comes to ball construction. However, with latex bladders, air won’t last as long as butyl bladders and will need more attention for proper inflation. Butyl-blend bladders hold in the air much better, but they are harder and less receptive in play. Mid-priced balls will usually have a mix of butyl and rubber. https://www.youtube.com/watch?v=c1SVcjYY6TE
