What is the function of diaper waistband on diapers?

The diaper waistband plays a critical role in the diaper's overall performance. It ensures a secure, comfortable fit, helps prevent leaks, provides flexibility and movement for the baby, and can be adjusted to suit different body shapes or sizes. In combination with other design features, the waistband helps ensure that the diaper performs well throughout the day, keeping the baby dry, comfortable, and leak-free.
