How to Choose Raw Materials for OEM Baby Diapers A Guide to the Main Product Structure

An OEM baby diaper may look simple, but it combines several functional materials, including the topsheet, acquisition layer, absorbent core, superabsorbent polymer (SAP), fluff pulp, backsheet, and fastening system. Each material has a specific role, and the complete configuration affects absorbency, softness, fit, and user experience. Jiayue matches baby diaper raw material options to the customer’s target market, product positioning, performance goals, and budget.

The top sheet is the layer that comes into direct contact with the skin, so its material has an important influence on wearing comfort. Jiayue offers both hot-air nonwoven and spunbond nonwoven top sheets. Hot-air nonwoven provides a softer and more cushioned feel, making it suitable for products that emphasize skin-friendly comfort. Spunbond nonwoven is generally thinner, with good strength and structural stability. Embossing and perforation can also be applied to adjust the surface structure, helping achieve different tactile properties and liquid acquisition performance.

The absorbent core is the key functional structure inside a diaper and directly affects absorption speed, product thickness, and liquid retention. Jiayue offers two main core options: SAP Paper Core and Fluff Pulp + SAP Core. SAP Paper Core mainly relies on SAP as the absorbent material, providing a thinner core structure, strong liquid retention, and reduced rewet. Fluff Pulp + SAP Core combines the liquid acquisition capability of fluff pulp with the retention performance of SAP, offering faster absorption and a relatively thicker, more substantial core structure. Different core solutions can be recommended according to specific product requirements.

The fastening system is another important part of diaper construction. It mainly consists of frontal and side fastening components that secure the diaper and adjust the fit. Frontal tape can use PP film, nonwoven, mesh, or brushed-loop materials. Side options include PP tape, hook-and-loop fastening tape, and elastic side ears; hook-and-loop tape is available in straight-cut and S-cut designs. The appropriate combination should be selected according to diaper size, waistband structure, and intended user group.

The backsheet provides leakage protection and forms the diaper’s outer protective layer. Jiayue offers PE film and cloth-like backsheet options. PE film provides reliable leakage protection, a lightweight structure, and cost-control advantages. A cloth-like backsheet generally combines breathable PE film with a nonwoven outer layer for a softer, textile-like feel. Backsheet colors, printed patterns, and logos can also be customized according to product positioning and brand design requirements.

For an OEM baby diaper project, raw material selection should be treated as a complete product system rather than a series of independent choices. The topsheet, acquisition layer, absorbent core, fastening system, and backsheet perform different functions while influencing one another. Configuration changes may affect softness, absorption speed, rewet, fit, thickness, and cost. The appropriate material solution should therefore be based on the target market and overall performance goals, rather than simply selecting the highest specification for every component.
