HC Industry is a professional trading company supplying full ranges of baby diaper raw materials — including nonwoven fabric, PE film, SAP, tapes, and elastic components — for OEM/ODM diaper manufacturers worldwide.
We provide one-stop sourcing solutions for all essential components used in baby diapers, ensuring quality consistency and stable supply for high-speed production lines.
Nonwoven fabric is the main surface material of baby diapers. The top sheet contacts the baby’s skin and ensures comfort, while the back sheet protects against leakage. PP spunbond nonwoven is widely used for its softness, breathability, and cost efficiency.
Hydrophilic Nonwoven: Designed for the top sheet. lt quickly allows liquid topassthrough to the absorbent core, keeping the baby's skin dry.
Hydrophobic Nonwoven: Used for the back sheet or leakage quard areas. lt repels liquidto prevent leakage and provides a soft, dry outer layer.
Material:Hydrophilic SSS Nonwoven/Hot Air Through/3D Ebossing Nonwoven/Hydrophobic SMMS Nonwoven
GSM: 10–30 g/m² (Top Sheet); 13–40 g/m² (Back Sheet)
Width: 60–2400 mm customizable
Color: White, blue, pink, custom options
Suitable for: High-speed baby diaper production lines Breathable or Unbreathable
Standard type: PP spunbond nonwoven for daily baby diapers
Premium type: Hydrophilic or embossed nonwoven for extra softness
HC Industry operates advanced nonwoven production lines to ensure consistent GSM, good tensile strength, and uniform texture. Our materials are SGS tested, skin-friendly, and available for customized finishes.
PE films act as the waterproof layer on the diaper backsheet, preventing leakage and maintaining flexibility. Laminated film can combine nonwoven softness with excellent barrier performance.
Hydrophilic Nonwoven: Designed for the top sheet. lt quickly allows liquid topassthrough to the absorbent core, keeping the baby's skin dry.
Hydrophobic Nonwoven: Used for the back sheet or leakage quard areas. lt repels liquidto prevent leakage and provides a soft, dry outer layer.Specification Range
Material: PE / PE+Nonwoven Laminate/Hot Air Through Non Woven Laminated with Breathable PE Film
GSM: 15–30 g/m²
Width: 60–1600 mm
Print: Up to 6 colors (flexographic or gravure)
Suitable for:Breathable or Unbreathable
Standard type: Plain PE film for economy baby diapers
Premium type: Printed or laminated PE film for branded packaging designs
HC Industry specializes in breathable and printed PE films with stable thickness and smooth surface. We offer multiple color and pattern options to match customer branding and diaper line requirements.
The absorbent core of baby diapers consists primarily of Super Absorbent Polymer (SAP) and fluff pulp. SAP rapidly absorbs and locks liquid within the core, while fluff pulp evenly distributes the liquid to maintain a dry surface. The synergy of these two materials directly determines the diaper’s absorbency, comfort, and rewet performance.
SAP: Sodium polyacrylate, absorption ≥ 50 g/g
Fluff Pulp: Softwood or mixed pulp, density 0.1–0.3 g/cm³
Core Ratio: 30–50% SAP + 50–70% Fluff Pulp (customizable according to diaper type and machine speed)
Standard type: Balanced SAP/fluff pulp ratio for stable absorbency and cost efficiency
Premium type: High-quality SAP and refined pulp for superior absorption rate and minimal rewet
Customized type: Core design optimized for machine type, production speed, and regional market preferences
At HC Industry, we emphasize brand reliability and material consistency. We cooperate with globally recognized suppliers to guarantee absorbent performance and production stability:
SAP Brands: Sumitomo, BASF, LG Chem – ensuring high absorption capacity, excellent gel stability, and fast liquid lock-in.
Fluff Pulp Brands: Georgia-Pacific (GP), International Paper, Domtar – providing clean, uniform fiber with high bulk and strength.
By integrating Sumitomo/BASF SAP and GP pulp, our absorbent cores achieve:
Fast liquid intake and even distribution
Long-lasting dryness and comfort
Reliable performance across both economy and premium diaper lines
We focus on brand-based sourcing and quality traceability, enabling our partners to maintain consistent diaper performance and manufacturing efficiency across different markets.
Although the main raw materials remain PP nonwoven, PE film, SAP, and fluff pulp, the diaper
industry is focusing on improving softness, absorption speed, and production efficiency.
Recent developments include:
Ultra-soft embossed nonwoven surface layers
Breathable PE films with better air permeability
Advanced SAP formulas for quick absorption
Lighter diaper core designs to reduce cost and material usage
HC Industry closely follows these trends, continuously improving product quality and process
stability to help customers stay competitive in the global market.
