Microporous Film: Breathable and Waterproof

What Is Microporous Film?

Microporous film is an advanced material engineered with countless microscopic pores that allow air and water vapor to pass through, while effectively blocking liquids, dust, and other external contaminants. This dual-function performance makes it essential in industries where breathability and barrier protection are both required.

Material Types & Properties

Microporous films are most commonly made from polyethylene (PE) or polypropylene (PP). Each material type delivers unique performance traits:

• PE Microporous Film
  Lightweight, flexible, and durable—ideal for hygiene products, construction membranes, and industrial packaging.

• PP Microporous Film
  Offers improved moisture-wicking and breathability, frequently used in medical-grade protective clothing and air-permeable packaging.

Specialty variants are also available for abrasion resistance, puncture prevention, and food-grade compliance, extending the utility of microporous film to customized applications.

Key Benefits

• Breathable Yet Waterproof
  Allows vapor to escape while blocking water droplets.

• Lightweight and Flexible
  Suitable for garments, masks, and wraparound surfaces.

• Durable and Tear-Resistant
  Withstands friction, bending, and demanding industrial conditions.

• Medical & Protective Use
  Widely used in face masks, surgical gowns, and isolation suits during the COVID-19 pandemic due to its barrier performance.

Applications Across Industries

• Medical textiles

• Disposable hygiene products

• Food and electronics packaging

• Waterproof construction membranes

• Protective apparel and rainwear
