PP frontal tape allows the mommy to adjust the diaper around the baby's waist and ensures a secure base to keep the diaper in place, which connects to the landing zone on the back portion of the diaper. After the frontal tape is secured, the side tapes are used to seal the diaper completely by connecting the front and back sections. The side tapes can be adjusted for a snug fit and sealed to prevent gaps, ensuring the diaper doesn't shift during movement.
