Leakproof Baby Diapers OEM Supplier

Product Overview of Cotton Hydrophilic Disposable Diapers

The Cotton Hydrophilic Disposable Baby Diaper line is engineered for infants across newborn to toddler stages, with the 6–12 month active phase as a primary use case. The diaper combines a cotton-rich hydrophilic top sheet, a composite absorbent core of fluff pulp and Japanese-imported superabsorbent polymer (SAP), and a 3D leak-prevention chassis. A color-change wetness indicator is integrated into the outer layer to support caregiver timing. The product is manufactured under ISO9001:2015 and GMP quality systems and carries FDA, CE, FSC, and BSCI certifications, supporting market entry in the European Union, North America, and Southeast Asia.

Material Composition and Absorption Core Technology

Hydrophilic Cotton-Rich Top Sheet

The top sheet is constructed from cotton-blend hydrophilic non-woven fabric. Hydrophilic fibers draw liquid through the surface within the first contact cycle, reducing residual moisture on the skin-facing layer. The cotton component contributes a lower-friction surface compared with polypropylene-only non-woven sheets, which is relevant for infants with sensitive skin.

Composite Absorbent Core

The absorbent core uses a two-component structure of cellulose fluff pulp for initial liquid distribution and Japanese-imported SAP for liquid retention. The SAP particles are distributed across the core in a fixed ratio to support even gel formation and minimize clumping after voiding. The core is wrapped in a tissue layer to contain fiber migration during use.

Wetness Indicator Mechanism

A water-based ink strip is applied to the outer surface of the diaper. When urine penetrates to the indicator layer, the ink undergoes a visible color shift, allowing caregivers to identify a soiled diaper without opening the garment. The indicator is positioned along the centerline of the diaper for visibility through standard outer packaging.

Technical Specifications

Functional Design of Leak Prevention and Fit

3D Leak Prevention Channel

The leg-opening area incorporates a three-dimensional barrier structure with dual elastic cuffs. The inner cuff stands vertically to create a first containment wall, while the outer cuff provides a secondary seal against the thigh. Elastic strands are spaced at 8 mm intervals along the leg opening to maintain tension consistency across the full length.

Ultra-Thin Profile

The finished diaper thickness measures approximately 4.5 mm in the core zone (size M, dry state). This profile reduces bulk between the legs during crawling and early walking, while the core structure maintains absorption capacity through SAP density rather than pulp volume.

Breathable Backsheet

The outer backsheet is a microporous polyethylene film with a water-vapor transmission rate that allows air exchange while blocking liquid penetration. This reduces heat and moisture accumulation in the covered area during extended wear.

Design Highlights

• Dual elastic leg cuffs

• 4.5 mm ultra-thin core
  

• Microporous breathable backsheet

• 8 mm elastic strand spacing

Certifications and Regulatory Compliance

The product holds the following certifications, each corresponding to a specific compliance domain of ISO9001:2015 for quality management systems; GMP for manufacturing hygiene and process control; FDA registration for infant hygiene products marketed in the United States; CE marking for conformity with EU general product safety directives; FSC certification for responsibly sourced pulp fiber; and BSCI certification for social compliance in the supply chain. Each certificate is available for review upon request and is subject to annual surveillance audits.

FAQ

Q1: What sizes are available for these baby diapers?

Six sizes are produced of NB, S, M, L, XL, and XXL. The 6-12 month age range typically corresponds to sizes M and L, though selection should be based on the infant's weight rather than age alone.

Q2: Can the packaging design be customized?

Yes. Both inner and outer packaging accept custom artwork. Buyers may submit design files in AI or PDF format; the production team provides layout proofs before printing. Options include color-printed bags, transparent bags, and printed cartons.

Q3: What is the minimum order quantity?

The MOQ is 1×40HQ container for both standard and custom orders. Up to three sizes may be mixed in a single container to support inventory planning across size curves.

Q4: What is the production lead time?

Standard orders ship within 25-30 days of deposit receipt and final design confirmation. Custom orders requiring new tooling or formula adjustments may require an additional 5-10 days. A confirmed schedule is provided with each order acknowledgment.

Q5: How can samples be requested?

Send an inquiry through the website contact form. Sample packs are shipped at no product charge, with the buyer covering courier fees. Tracking information is provided upon dispatch.
