What is Breathable film

Breathable film, also known as breathable membrane or breathable fabric, is a material designed to separate air and other substances, allowing air to pass through while blocking the flow of liquid water. It can be applied in various fields such as the construction industry, the medical sector, and outdoor clothing, often with different material designs tailored to the specific application.

In the construction industry, breathable films are typically used as part of the building's exterior envelope. They are usually installed on the exterior of a building, placed beneath the cladding or roofing materials. These films aid in managing moisture within the structure, permitting water vapor generated inside the building to escape while preventing rainwater infiltration. This can help prevent issues like condensation and mold growth.

In the medical field, breathable films are utilized in the production of wound dressings, surgical drapes, and various other medical products. They allow for the exchange of air and moisture between wounds and the surrounding environment, facilitating wound healing and preventing excessive moisture buildup.

In outdoor clothing, breathable fabrics are employed to create waterproof and breathable garments. These fabrics are designed to resist rain and snow while enabling sweat and moisture produced by the body to pass through, keeping the wearer comfortable and dry.

Breathable films find application in countless areas, and in companies like Kae Hwa Industrial .CO.,LTD, they are used in over 30 different sectors.

Breathable films are typically made from materials like microporous polyethylene or polypropylene, which have micro-sized pores that permit water vapor molecules to pass while being small enough to block the flow of liquid water. The specific characteristics and applications of breathable films can vary depending on their intended use and the materials used in their design.
