When evaluating baby diapers, focus on the Absorbency Core, which should ideally use a high-quality Super Absorbent Polymer (SAP) mixed with fluff pulp to ensure rapid liquid locking. Check the Breathability of the backsheet; a microporous PE film or non-woven cloth-like backsheet is essential to prevent diaper rash. Additionally, ensure the Elastic Waistband and Triple Leak Guards provide a snug fit without restricting movement, and verify that the Wetness Indicator is sensitive enough for end-user convenience.
