Does the breathable film maintain its performance during converting and lamination?
Yes. One of the biggest challenges in functional film use is maintaining the microporous structure under the stress of secondary processing. Kae Hwa films are specifically engineered for high-tension converting environments.
Thermal Resistance
Our films are designed to withstand the heat of thermal lamination without collapsing the micro-pores, ensuring that your final composite maintains the exact WVTR you designed for.
Dimensional Stability
High-speed converting machines apply significant tension. Our precision casting ensures uniform molecular orientation, preventing the film from “necking” during winding.
Adhesion Compatibility
Whether using ultrasonic welding or hot-melt adhesives, our film surfaces are optimized for high peel strength, ensuring no delamination in the finished product.
Quality Assurance: Every roll is tested for consistent tensile strength and thickness tolerance (within 10um), meeting ISO 9001 standards to guarantee hassle-free converting for Type 4B/5B/6B industrial applications.
