The tape at the back of the disposal tape is for storage purposes. After the diaper is used up, roll the diaper into a roll, tie the diaper into a roll and stick it with the tape so that the contents of the nappy do not flow out. Babies' skin is extremely delicate. If they are immersed in urine for a long time or if their nappies are damp because they are impermeable, a small red rash will appear on their buttocks or their skin will become rougher, which is called "nappy rash" or "red bottom". It is important to take care of your bottom by washing it promptly after passing urine and faeces and using buttock cream, and changing nappies regularly to keep your bottom dry.
