## Key takeaways

- Kae Hwa designs many of its PE and PP membranes for full recyclability using a mono-material strategy that pairs the film with a compatible nonwoven substrate into a single-polymer structure.
- This single-polymer structure can be recycled as a whole, eliminating the need for energy-intensive material separation required by mixed-material laminates.
- Kae Hwa's PP Non-Filler technology uses crystalline stretching instead of mineral additives for a powder-free, non-toxic film, and the company sources GRS-certified post-consumer recycled resins to close the loop.

## Frequently asked questions

### Can Kae Hwa's waterproof and breathable films be fully recycled?

Yes. Kae Hwa designs many of its PE and PP membranes for full recyclability using a mono-material strategy that pairs the film with a compatible nonwoven substrate, creating a single-polymer structure that can be recycled whole without energy-intensive separation. The company also uses PP Non-Filler technology, which relies on crystalline stretching instead of mineral additives for a powder-free, non-toxic film, and actively sources Global Recycle Standard (GRS) certified post-consumer recycled resins to close the loop from raw material to end-of-life repurposing.

### What makes PP Non-Filler technology more environmentally friendly than standard filled films?

Standard breathable PP films often rely on mineral additives (fillers) to create porosity, which can leave powder residue and complicate recycling. Kae Hwa's PP Non-Filler technology instead uses crystalline stretching to create the same breathable structure without mineral additives, resulting in a powder-free, non-toxic film that is easier to recycle.
