## Key takeaways

- MicroBreath™ PE is engineered for maximum cloth-like softness and flexibility, with a lower melting point that suits high-speed thermal lamination in hygiene production like diaper backsheets and incontinence products.
- MicroBreath™ PP offers superior mechanical strength, higher processing-temperature resistance, and greater tensile resistance under stress, making it better suited to industrial protective coveralls and demanding applications.
- Both PE and PP belong to the same MicroBreath™ microporous film series — the choice between them comes down to matching softness versus strength to the end-use environment.

## Frequently asked questions

### What is the difference between MicroBreath PE and PP breathable films?

MicroBreath PE is engineered for maximum cloth-like softness and flexibility, with a lower melting point that makes it highly compatible with high-speed thermal lamination in hygiene production, so it is ideal for baby diaper backsheets, adult incontinence products, and standard hygiene materials. MicroBreath PP instead offers superior mechanical strength and dimensional stability, withstanding higher processing temperatures and greater tensile resistance under heavy stress, making it better suited to industrial protective coveralls and other demanding applications.

### Which industries typically use MicroBreath™ PP over PE?

Industries that need extra mechanical durability under heat or stress — such as industrial protective coveralls — typically choose MicroBreath™ PP, while hygiene product manufacturers favor PE for its softness and low-temperature lamination bondability.
