Breathable Cast PE backsheets are not "better" than non-breathable ones. They're different — engineered for different absorbent systems, different wearer durations, and different price points.
When breathable wins
- Long-wear products (overnight diapers, adult pant-style).
- Premium SKUs where "cloth-like" feel is the brand cue.
- Hot, humid climates where wearer comfort is the leading complaint.
- Products with low-to-medium SAP loading that benefit from vapor release.
When non-breathable wins
- Short-duration single-use products (hospital underpads, light bladder pads).
- Value-tier SKUs where price-to-perform is the priority.
- Products whose absorbent core is engineered to retain moisture inside.
- Outer-wrap and packaging-grade applications.
When you need both
- Most converters run both — premium SKUs use breathable, value SKUs use non-breathable, sometimes on the same line with a quick changeover.
