    Pressure. The pressure inside the ball is try to be the same as the pressure outside. Therefore if they are stored in high pressure the inside will at least start out at high pressure. Which will make them bounce better.

    To keep them clean. Who wants dirty balls? Tennis balls are supposed to be nice and bright yellow. :)

    Actually, they are not in a vacuum container, but a pressurized container to keep the pressure up inside the balls. They do not bounce well with low pressure.

    They’re not really packed in a vacuum, i.e., in a container in which all the air has been removed, but they are sealed in a container at the same air pressure at which the balls are inflated.

    Tennis balls will be packed in containers at varying pressures, depending on what playing surface they’re intended to be used on.

    Keeps them at top quality!

    They are packaged this way to maintain the air pressure inside the ball. Once a ball is taken out of the pressurized container, it begins to lose air pressure, especially when it is played with.
