Breathable Film Applications

– Sanitary Products: As a core functional material, breathable film is widely used in disposable hygiene products such as baby diapers, adult incontinence pads, and feminine hygiene products. It enables the rapid discharge of moisture and heat generated by the human body while preventing the reverse penetration of liquid, effectively maintaining the dryness and comfort of the user’s skin and reducing the risk of skin irritation.

– Protective Products: It is an essential component in protective clothing, medical surgical gowns, and disposable protective masks. The breathable film ensures that the wearer can breathe smoothly by allowing air circulation, while blocking the invasion of dust, droplets, and microorganisms, achieving a balance between protection performance and wearing comfort, which is particularly critical for medical staff and personnel working in dusty or hazardous environments.

– Roofing Membrane: Applied in the field of building waterproofing, breathable film is used as a roofing underlayment membrane. It can discharge the water vapor trapped in the roof structure to avoid mold growth, structural corrosion, and damage to the waterproof layer caused by long-term moisture accumulation. 与此同时, it enhances the thermal insulation performance of the roof and improves the overall durability and service life of the building envelope.

– Packing Products: Suitable for packaging materials that require breathability, such as fresh food packaging (e.g., fruits, vegetables, and fresh meat), agricultural product packaging (e.g., seeds, flowers), 和工业产品包装 (e.g., electronic components, mechanical parts). The breathable film regulates the gas composition inside the package, slows down the spoilage of fresh products, prevents moisture accumulation in industrial products, and ensures the quality and safety of the packaged items during storage and transportation.
