Key Features and Benefits
1. Strong and Stable Adhesion
The adhesive provides reliable bonding to commonly used hygiene substrates such as: Nonwoven fabrics, PE breathable films, Tissue and absorbent cores, Elastic components.
It maintains adhesion under tension, bending, and long-term wear conditions.
2. Excellent Skin-Friendly Performance
Formulated for hygiene-grade applications, the adhesive is designed with Low odor formulation, Reduced volatile components (low VOC), Clean application performance.
This makes it suitable for products that come into close contact with human skin.
3. High-Speed Production Compatibility
Modern hygiene manufacturing requires adhesives that perform consistently under high line speeds. This HMPSA offers Stable melt viscosity, Smooth spray or slot coating performance, Low stringing and clean machining, Fast setting time for efficient production
4. Balanced Tack and Cohesion
The product is engineered to ensure Immediate tack for reliable positioning, Strong internal cohesion to prevent adhesive transfer or leakage,Controlled open time for flexible processing windows
5. Thermal Stability and Processing Safety
The adhesive maintains stable performance under continuous heating conditions, reducing Carbonization risk, Equipment clogging, Downtime caused by residue buildup
Typical Applications in Baby Diapers
1. Diaper Construction Bonding
Used for assembling multiple diaper layers, including:
- Top sheet bonding
- Back sheet lamination
- Core fixation
- Nonwoven fabric attachment
2. Elastic Attachment
Provides secure bonding for:
- Leg elastics
- Waistband elastics
