<p>There is no canon information on how they work so far, but I've always thought that it was something to do with light manipulation. If a pokemon is released from a pokeball then there is a bright glow that is also emitted at the same time. The ball capsule alone has been seen used without a seal and the release is normal. I believe that is because the light was able to pass through the ball capsule without being impeded by a seal. </p>

<p>However when a seal is used the light has to travel through the seal on the way out and therefore takes on the appearance designated by the seal, similar to how holograms are theorized to work. This effect fades when the pokemon appears because that when the light usually fades. As I said though this is all theory and personal opinion. Hope this helps. </p>

but the capsule opens as the ball does, so how will the light pass through the capsule, i mean, when the ball opens, the capsule opens in the same way, therefore light from inside of the pokeball should not be able to pass through the capsule, and the seal is on the capsule so it wouldn't exactly work, thanks for the answer though

<p>In the Pokémon anime and manga, the Poké Ball seal and ball capsule allows the Pokémon to get a fancy entrance, it is mainly used in contests but can be bought and used for fun. Is there any explanation of how these work?</p>

<p>Here is a complete Poké Ball with capsule and seal:  </p>

Do you mean [seals](http://bulbapedia.bulbagarden.net/wiki/Seal) on [ball capsules](http://bulbapedia.bulbagarden.net/wiki/Ball_Capsule)? If so, they're only in Gen IV and there's no explanation of the science given.
