Abstract
The trade-off between breathability and strength properties has (grudgingly) been accepted by producers of microvoided film, such as for diaper backsheet. The key resin, additive, film fabrication, and film stretching parameters that impact moisture vapor transmission as well as the physical attributes of the film have been identified. The understanding of these complex interactions provided the basis for modification of the polyethylene (PE) molecular architecture that promotes both high MVTR and high-strength properties in microvoided films. This information has resulted in new polyethylene resins for the breathable film market.
