Inside the ball a bladder is placed, the bladers are usually made of either latex or butyl. After cutting the panels , Silk screen printing is done on the peices according to the design and requirements of the customers.
Then the pannels are Hand stitched with Pre Puches Stitch Holes togeather with a bladder inside the pannels, this way 32 Panels are held by 720 stitches in a soccer ball. Official weight 420~445 grams with ball pressure 0.8 bar Circumference for size 5 is 68.5cm to 69.5cm Rebound: 120~150cm at 20 C Temperature

Law 2 of the game specifies that the ball is an air-filled sphere with a circumference of 68–70 cm (or 27–28 inches), a weight of 410–450 g (or 14–16 ounces), inflated to a pressure of 60–110 kPa (or 8.5–15.6 psi), and covered in leather or “other suitable material”.  The weight specified for a ball is the dry weight: older balls often became significantly heavier in the course of a match played in wet weather. The standard ball is a Size 5.

Most modern footballs are stitched from 32 panels of waterproofed leather or plastic: pigskin, 12 regular pentagons and 20 regular hexagons. The 32-panel configuration is similar to the polyhedron known as the truncated icosahedron, except that it is more spherical, because the faces bulge due to the pressure of the air inside. The first 32-panel ball was marketed by Select in the 1950s in Denmark. This configuration became common throughout Continental Europe in the 1960s, and was publicised worldwide by the Adidas Telstar, the official ball of the 1970 World Cup.
Older balls were usually stitched from 18 oblong non-waterproof leather panels, similar to the design of modern volleyballs and Gaelic footballs, and laced to allow access to the internal air bladder
The official FIFA World Cup football for Germany 2006 matches was the 14-panel Adidas +Teamgeist. It was made in Thailand by Adidas, who have provided the official match balls for the tournament since 1970, and is a “thermally bonded” machine-pressed ball, rather than a traditionally stitched one. For future world cups, FIFA is hoping to alternate between Nike and Adidas for match balls.
Another ball with an innovative pattern is the 26-panel Mitre PRO 100T.
There are also indoor footballs, which are made of one or two pieces of plastic. Often these have designs printed on them to resemble a stitched leather ball.
