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.
The first edition of our newly developed dual bonded production method is used in the new soccer ball called BLAZE DB. The construction of this ball consists of a PU-material laminated with 3 mm foam. Next, two layers of textile underlining are laminated to the foam layer to add stability. The panels are then 3D printed with 3mm edge glue and stitched by hand, In the heat mold the glue is activated to hide the stitches. Next, the seam sealing is done by hand. The glue in the seams reduces the water uptake significantly. The bladder inside is a SR-bladder with excellent air retention. The result is a soccer ball with both stability, control and a softer touch compared to other balls in the range.

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
