HMPSA for Hygiene Care: Construction, Elastic & Positioning Adhesives

At the core of every reliable disposable hygiene product lies an invisible champion—the adhesive. Our Hot Melt Pressure Sensitive Adhesive (HMPSA) for Hygiene Products is engineered to meet the stringent demands of high-speed manufacturing while providing ultimate comfort, safety, and performance for end users.

From ultra-thin baby diapers and feminine pads to high-absorbency adult incontinence products, our HMPSA portfolio delivers exceptional bond strength, zero odor, and total peace of mind.

Product Overview

This HMPSA is formulated using carefully selected base polymers, tackifying resins, and stabilizers to ensure a balanced combination of tack, cohesion, and thermal stability. It is designed to provide instant adhesion upon application while maintaining flexibility after cooling, making it suitable for complex multi-layer hygiene structures.

Unlike solvent-based adhesives, hot melt pressure sensitive adhesive contains 100% solid content, which eliminates solvent emissions and improves production safety and environmental performance.

Key Application Areas

Our hygiene adhesives are specifically tailored to excel across four core application modules:

• Construction Bonding (Structural Lamination): Ensures strong, permanent lamination between non-woven fabric, absorbent core (SAP/fluff pulp), and breathable PE backsheets without compromising product softness or flexibility.

• Elastic Strand Attachment: Engineered with superior creep resistance to securely lock elastomeric spandex threads in place at leg cuffs and waistbands, preventing leakage while ensuring a snug, comfortable fit.

• Positioning & Garment Attachment: Formulated for feminine sanitary pads and panty liners. Delivers reliable grip on various underwear fabrics during use, followed by clean, residue-free removal upon disposal.

• Packaging & Auxiliary Sealing: Provides quick, clean sealing for individual product wrappers and landing zone tapes on baby diapers.

FAQ

Q: What is a hot melt pressure sensitive adhesive (HMPSA)?

A: Hot Melt Pressure Sensitive Adhesive (HMPSA) is a solvent-free adhesive that is applied in a molten state and develops permanent tack after cooling. Unlike reactive adhesives, HMPSA does not require curing. It provides instant bonding with light pressure, making it ideal for high-speed hygiene product manufacturing.

Q: Can you provide free samples?

A: Yes.

Q: How can stringing during application be reduced?

A: Stringing may result from inappropriate application conditions rather than the adhesive itself. 

Possible solutions include:

• Lower the application temperature slightly.
• Optimize spray pressure and nozzle settings.
• Reduce the distance between the nozzle and substrate.
• Increase production speed if applicable.
• Select an adhesive grade with lower stringing characteristics.
