When launching or expanding a private label diaper brand, one of the most critical decisions for brand owners, wholesalers, and sourcing managers is choosing the right diaper core technology. The core isn’t just about absorbency—it defines overall diaper performance, thickness, breathability, and even how the diaper feels in-hand and on the baby.
Two of the most common options available from OEM diaper manufacturers today are wood-pulp core baby diapers и ultra-thin core baby diapers. Each core structure has unique benefits and serves specific market segments. Understanding their pros, cons, and market appeal will help you make better decisions for your custom diaper line.

What Is a Wood-Pulp Core Diaper?
Traditionally, disposable baby diapers have been built using a core composed of fluff pulp (wood pulp) combined with SAP (super absorbent polymer). Fluff pulp is a fibrous material derived from trees, most commonly pine. It is known for its bulk and fluid dispersion ability, making it a cost-effective and familiar option for many brands.
Advantages:
Cost-effective manufacturing: Wood pulp is generally cheaper to source and process.
High absorbency volume: Good at absorbing large quantities of fluid quickly.
Ideal for overnight use: Due to their thickness and absorbency reliability.
Limitations:
Bulkier feel: Thicker structure may reduce comfort and restrict baby mobility.
Less modern appearance: Bulkier diapers may feel outdated in premium markets.
Not ideal for sleek packaging: Limits branding possibilities for minimalist or premium packaging designs.
What Is an Ultra-Thin Core Diaper?
Ultra-thin disposable diapers use a core with minimal or no fluff pulp. Instead, they rely on advanced SAP distribution, often using air-laid paper, absorbent sheets, or high-efficiency layers to maintain performance while reducing bulk.
Advantages:
Modern, sleek design: Thinner diapers often feel more premium and appeal to young parents and online shoppers.
Lightweight and breathable: Perfect for hot climates or active babies.
Efficient liquid lock: Performs as well or better than traditional cores in moisture retention tests.
Limitations:
Higher material costs: The use of advanced SAP and absorbent papers increases production costs.
Requires skilled manufacturing: Not all diaper OEM factories have the equipment for stable ultra-thin diaper production.
May appear too thin: Some traditional consumers associate thickness with protection and may hesitate.
