## Key takeaways

- Lamination bonds the delicate breathable membrane to a soft nonwoven fabric, giving diapers and gowns the mechanical strength to withstand movement and stretching without tearing.
- Kae Hwa uses solvent-free thermal bonding or ultrasonic technology rather than chemical adhesives, leaving no toxic residues or VOCs that could irritate sensitive skin.
- Because the company controls the entire process from film extrusion onward, materials are tested and verified to be hypoallergenic and non-toxic before reaching a diaper or gown.

## Frequently asked questions

### Why is lamination necessary, and is the process safe for sensitive baby skin?

Lamination bonds the delicate breathable membrane to a soft nonwoven fabric, giving diapers and gowns the mechanical strength to withstand movement and stretching without tearing. It is safe for sensitive baby skin because Kae Hwa uses solvent-free thermal bonding or ultrasonic technology rather than chemical adhesives, leaving no toxic residues or VOCs, and because the company controls the entire process from film extrusion onward, materials are tested and verified to be hypoallergenic and non-toxic before reaching a diaper or gown.

### What would happen if a breathable film were used without lamination?

Pure breathable film on its own is extremely thin and delicate, so without lamination to a nonwoven fabric it would lack the mechanical strength needed to withstand movement and stretching, making it prone to tearing in products like diapers and gowns.
