PE Microporous Breathable Film – MicroBreath Series

Kae Hwa’s MicroBreath™ PE Microporous Breathable Film is engineered from high-quality polyethylene and refined through precise microporous technology to achieve an optimal balance of waterproof protection and vapor transmission. Designed for hygiene, medical, industrial, and multi-purpose packaging applications, this film delivers reliable breathability, softness, and barrier performance while remaining lightweight and adaptable for various converting processes.

As the most customizable membrane within the MicroBreath™ series, our PE breathable film can be tailored in color, surface texture, and printing. Through proprietary masterbatch formulation, the membrane can be colored to enhance product identity; embossing techniques introduce distinct tactile patterns; and advanced printing treatments ensure high-definition graphics with strong ink adhesion. This versatility allows the PE microporous film to combine functional protection with enhanced aesthetics—making it suitable for premium packaging, diaper backsheets, protective fabrics, and branded consumer materials.

With more than six decades of polymer expertise, Kae Hwa ensures every PE breathable membrane provides consistent WVTR performance, waterproof integrity, and compatibility with lamination, heat-sealing, and high-speed converting. Whether for performance, appearance, or branding needs, our PE microporous film offers a balanced and customizable solution for diverse industries.

WATERPROOF & BREATHABLE STRUCTURAL PERFORMANCE

The MicroBreath™ PE membrane features a dense microporous structure that physically prevents water droplets and contaminants from penetrating through the film. When laminated on nonwoven substrates, it delivers stable waterproof performance while maintaining high WVTR levels essential for comfort and moisture management.

Through consistent pore formation and uniform distribution, MicroBreath™ maintains a strong balance between liquid barrier function and vapor permeability—making it ideal for protective apparel, diaper back sheets, and moisture-regulating packaging.

CONSISTENT PERFORMANCE YOU CAN DEPEND ON

Every MicroBreath™ PE film undergoes strict in-line quality control, including pore-size consistency, basis-weight stability, and mechanical-strength monitoring.

This ensures that every batch meets the required WVTR, waterproofness, and tensile performance standards even after converting, heat exposure, or storage.

The membrane’s structural uniformity is the key to long-term durability. Whether under flexing, pressure, or repeated use, MicroBreath™ PE maintains stable protection and airflow.

SOFT, FLEXIBLE & PROCESS-FRIENDLY FOR HIGH-YIELD LAMINATION

MicroBreath™ PE films offer a soft, cloth-like handfeel with excellent thermal stability, making them suitable for various lamination processes—including hot-melt adhesive bonding, extrusion coating, and ultrasonic sealing.

The film is engineered to resist pin-holing, shrinkage, and deformation during converting, which results in:

  • Higher lamination efficiency
  • More stable roll-to-roll processability
  • Improved seam integrity
  • Reduced production waste

This makes MicroBreath™ PE especially advantageous for large-volume hygiene converters, medical fabric manufacturers, and industrial protective material producers.

CUSTOMIZABLE IN COLOR, TEXTURE & PRINTING

MicroBreath™ PE is also the most versatile membrane in the series, supporting:

  • Color masterbatch customization
  • Embossed textures
  • Multi-color rotogravure printing

Based on Kae Hwa’s six decades of polymer expertise, each visual variant is engineered to maintain its functional performance while enhancing product identity and aesthetics.
