What Are the Raw Materials for Baby Diaper Production?
1️⃣ Nonwoven Fabric (Top Sheet & Back Sheet)
Top sheet: Soft and skin-friendly, directly contacts baby skin
Back sheet: Waterproof layer to prevent leakage
Usually made from polypropylene (PP) spunbond or SMS nonwoven
✅ Welldone machines are designed to handle various grades of nonwoven fabric with precision unwinding systems.
2️⃣ Fluff Pulp
The absorbent base layer of the diaper
Made from bleached wood pulp (from USA, Brazil, or Nordic countries)
Often used with SAP for better liquid retention
💡 Our hammer mill system ensures uniform fiber size for superior absorbency.
3️⃣ SAP (Super Absorbent Polymer)
Turns liquid into gel
Crucial for keeping the diaper dry
Applied through SAP spraying or metering systems
✅ Welldone’s dosing systems allow precise SAP distribution to reduce cost and enhance performance.
4️⃣ Elastic Components
Used in the leg cuffs, waistband, and side panels
Materials: spandex yarn or elastic film
Provide flexibility and a better fit
5️⃣ Side Tapes & Frontal Tapes
Help fasten the diaper securely
Typically made from PP film or woven/nonwoven laminated with adhesive
6️⃣ ADL (Acquisition Distribution Layer)
Sits between the top sheet and core
Spreads liquid evenly and improves rewet performance
7️⃣ Hot Melt Adhesive
Used to bond different layers
Applied via spray, stripe, or slot nozzle glue guns
8️⃣ Release Paper (Optional)
For diapers with reusable closure systems
Protects the adhesive until use
