Abstract

A sport ball may include a casing, a bladder, and a valve. The casing forms at least a portion of an exterior surface of the ball. The bladder is located within the casing for enclosing a pressurized fluid, and the bladder may be formed from a material that includes a first layer of thermoplastic polymer material and a second layer of a barrier material. The valve is for introducing the fluid to the bladder, and the valve is secured to the bladder and accessible from an exterior of the casing. A tie layer may be located between the flange and a surface of the bladder to join the flange to the bladder.
