Premium Hot Melt Pressure Sensitive Adhesive (HMPSA) for Female Care

Product Overview

Our specialized Hot Melt Pressure Sensitive Adhesive (HMPSA) series is engineered specifically for modern feminine hygiene products, including sanitary napkins, panty liners, and feminine care pads. Formulated with high-grade synthetic rubbers and hydrogenated resins, our adhesives deliver superior bonding performance, excellent thermal stability, and maximum comfort for end users.

Whether applied as a positioning adhesive (wing and backsheet attachment to garments) or a construction adhesive (multi-layer pad lamination), this HMPSA ensures consistent adhesion without residue, skin irritation, or bleed-through.

Core Applications in Female Care

Our HMPSA series covers all critical application zones across feminine care product manufacturing:

1. Positioning Adhesive (Back & Wing Glue)

• Function: Anchors the sanitary pad securely to undergarments during movement.

• Key Feature: Optimal balance of high initial tack and clean peelability. Leaves zero sticky residue on cotton or synthetic fabrics when removed.

2. Construction Adhesive (Layer Lamination)

• Function: Bonds non-woven topsheets, acquisition distribution layers (ADL), absorbent cores, and PE backsheets together.

• Key Feature: Excellent penetration and creep resistance, keeping the pad intact even under moisture or mechanical stress.

Key Performance Features & Benefits

• Skin-Friendly & Odor-Free: Formulated to meet strict toxicological and dermatological safety standards (low VOCs, non-irritating, hypoallergenic).

• Excellent High-Speed Runnability: Works smoothly on ultra-fast continuous manufacturing lines without stringing, tailing, or nozzle clogging.

• Fabric-Safe Adhesion: Delivers strong shear resistance during wear while offering smooth, quiet, and residue-free removal.

• Superior Thermal & Color Stability: High resistance to thermal degradation during melting, maintaining a water-white or light-yellow appearance and stable viscosity in glue tanks.

• Versatile Application Coating: Compatible with slot die, spiral spray, fine fiberization, and multi-bead coating equipment.

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: Can the adhesive withstand storage and transportation in hot climates?

A: Yes. Our adhesives are formulated to maintain stable performance under a wide range of environmental conditions. We can also recommend climate-specific grades for tropical or high-temperature regions.
