Adult Incontinence Underpad Construction Hot Melt PSA Adhesive for Nonwoven SAP Core Lamination
Adult Incontinence Underpad Construction Hot Melt PSA Adhesive
JCC WSD5001J is a hot melt pressure sensitive adhesive (HMPSA) specially formulated for the construction and lamination of disposable adult incontinence underpads. It delivers strong, consistent bonding between nonwoven topsheet, tissue layers, SAP absorbent core and PE film backsheet, ensuring the multi-layer structure stays intact during use and removal.
Engineered for high-speed production lines, WSD5001J offers excellent wetting, fast setting and low stringing, which keeps converting machines running smoothly with minimal downtime and waste.
Key Features & Advantages
- Multi-layer bonding: firmly bonds nonwoven, tissue, SAP core and PE film in one pass.
- Anti-migration: low oil migration prevents adhesive bleed-through to the pad surface.
- High-speed compatibility: fast setting and low stringing for continuous production lines.
- Low odor & no fluorescence: meets hygiene product safety requirements.
- Good thermal stability: stable viscosity during prolonged heating, reducing char and gel formation.
- Non-toxic: skin-contact safe for disposable medical and care products.
Main Applications
- Adult incontinence underpads (construction & lamination)
- Disposable bed protection pads
- Multi-layer nonwoven / tissue / film composite structures
- Absorbent core fixation in hygiene products

Frequently Asked Questions
Q1: Can WSD6001J be used on high-speed underpad converting lines?
A: Yes. It is formulated with fast setting and low stringing behaviour to support line speeds typical of adult underpad production.
Q2: Will the adhesive migrate or bleed through the pad?
A: No. The low-migration formulation keeps oil and tackifier from penetrating the topsheet, leaving a clean surface.
Q3: Is it safe for skin contact?
A: Yes. It is non-toxic, low odor and free of fluorescence, complying with hygiene product safety standards.
Q4: What packaging is available?
A: 25kg per carton, or customized packaging upon request.
