What makes one diaper more absorbent, breathable, or skin-friendly than another? It all comes down to the raw materials. From newborns to adults, diaper users have vastly different needs—and manufacturers must choose their materials wisely to deliver comfort, performance, and safety.
The Core Components of Modern Diapers
Most disposable diapers are composed of two main parts: the core and the chassis. The core is responsible for absorbing and retaining liquid, while the chassis provides structure, fit, and protection against leakage.
Material Differences Across Major Diaper Brands
Diaper manufacturers rely on different combinations of these raw materials based on brand positioning, cost, and market expectations.
#1Pampers

Pampers (Procter & Gamble) typically uses a high SAP-to-pulp ratio, resulting in ultra-thin but highly absorbent diapers. Their topsheets are treated with lotion to reduce irritation, and their ADL is designed for rapid urine distribution.
#2Huggies

Huggies (Kimberly-Clark) often retains more fluff pulp in the core to provide a cushiony, bulkier feel. Their waistband designs are stretchier, focusing on active babies who need flexibility.
OEM and Generic Brands may vary widely in material quality. Some focus on cost-effectiveness and retain more pulp, less SAP, or use lower-cost nonwoven fabrics. However, many OEM factories today offer biodegradable or plant-based materials to meet growing environmental demand.
Raw Material Selection Based on User Needs
Material choice isn’t just about brand—it also depends heavily on the intended user group.
User Group | Material Priorities | Recommended Features |
---|---|---|
Newborns and Infants | Ultra-soft topsheet, breathable backsheet, hypoallergenic, lotion-treated fabrics | Balanced SAP and fluff ratio to reduce bulk while maintaining high absorbency. Skin protection is essential. |
Toddlers / Overnight | Higher SAP content, double leak guards, reinforced leg cuffs, breathable construction | Enhanced absorbency and leak prevention for longer wear times, especially during sleep. |
Adults / Elderly | High SAP volume, wide acquisition and distribution layer, soft but durable elastic materials | Maximum liquid distribution and retention, with added comfort for extended use and mobility support. |
A Real-World Example: KeiAnn Baby Diapers

KeiAnn baby diapers are a strong example of thoughtful material selection tailored to infant needs. They feature a skin-friendly, hypoallergenic nonwoven topsheet, a high-performance SAP core, and a structured distribution layer that quickly locks in moisture. This combination keeps the diaper surface dry and reduces the risk of diaper rash. With multiple variants designed for different baby stages, KeiAnn offers a reliable solution for parents seeking both comfort and performance in one product.
Sustainability and Innovation in Diaper Materials
The diaper industry is also shifting toward sustainability. Some manufacturers are experimenting with biodegradable fluff pulp, plant-based SAP alternatives, and compostable backsheet films. These innovations aim to reduce environmental impact while maintaining product performance.
Certifications like ISO, SGS, and CE often indicate that raw materials meet international standards for health, safety, and quality—especially for export-driven production.
Conclusion
The effectiveness of a diaper depends less on the brand name and more on the raw materials inside it. By understanding the roles and variations of fluff pulp, SAP, nonwoven fabrics, and elastic components, buyers and consumers can make informed decisions that align with comfort, performance, and cost needs. Whether you’re developing a private label diaper brand or choosing the right product for your family, a deeper understanding of diaper raw materials is the first step toward better outcomes.
