Elastic adhesive is a type of hot melt adhesive specifically engineered for elastic bonding in disposable hygiene products. It maintains stable adhesion while allowing materials to stretch and recover repeatedly without bond failure.
It is widely used in high-speed hygiene manufacturing lines where both flexibility and bonding strength are required.
Working Principle
Elastic hot melt adhesive is applied in molten state and quickly solidifies after cooling.
During use, it forms a flexible bonding layer that can:
Stretch together with elastic fibers
Recover its original structure after deformation
Maintain adhesion under continuous stress
Main Application Areas
Baby diaper leg cuffs and waistbands
Adult incontinence product elastic zones
Sanitary napkin side elastic structures
Underpads and absorbent hygiene composites
Elastic hot melt adhesive is commonly compatible with:
Polyethylene (PE) film
Polypropylene (PP) nonwoven fabric
Spandex / Lycra elastic fibers
Natural or synthetic rubber bands
