While flat belt conveyors use a single, continuous loop of material, modular conveyor belt systems use a single loop made of countless interlocked pieces, usually made of hard plastic. These segments can be removed and replaced individually, in contrast to having to discard the entire belt. They’re also easier to wash, as well as more resistant to sharp and abrasive materials. This makes modular belt conveyors simpler to maintain and repair than their flat belt counterparts.
