How to Choose Raw Materials for OEM Baby Diapers? A Guide to the Main Product Structure
A baby diaper may look simple, but it is actually made from multiple materials with different functions, including the top sheet, absorbent core, SAP, fluff pulp, back sheet, and fastening system. Each material performs a specific role, while the overall material combination affects absorbency, softness, fit, and the overall user experience. At Jiayue, raw material configurations can be matched according to the customer’s target market, product positioning, and cost requirements.
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, mainly consisting of the frontal tape and side tape, which help secure the diaper and adjust the fit during use. The frontal tape can be customized with materials such as PP film, nonwoven, mesh, or brushed-loop material. Side fastening options include PP tape, hook-and-loop fastening tape, and elastic side ears, while hook-and-loop fastening tape can also be produced in straight-cut or S-cut designs. The appropriate combination should be selected according to diaper size, waistband structure, and the intended user group.
The back sheet mainly provides leakage protection and forms the outer protective layer of the diaper. Jiayue offers PE film back sheet and Cloth-like back sheet options. PE film provides reliable leakage protection, a lightweight structure, and advantages in cost control. A cloth-like back sheet generally combines a breathable PE film with a nonwoven outer layer, providing a softer, more textile-like feel. Back sheet colors, printed patterns, and logos can also be customized according to product positioning and brand design requirements.
For OEM baby diapers, raw material selection should be considered as a complete product system rather than a series of independent material choices. The top sheet, acquisition layer, absorbent core, fastening system, and back sheet each perform different functions while also influencing one another. Changes in material configuration may affect softness, absorption speed, rewet, fit, product thickness, and overall cost. Therefore, an appropriate OEM material solution should be developed based on the overall performance target of the product, rather than simply selecting the highest specification for each individual material.
