Casting Film Process
PRECISION CASTING TECHNOLOGY

Where Precision
Begins at the Stage

At Kae Hwa Industrial Co., Ltd., precision begins at the film stage. Our casting lines achieve consistent film formation within ±0.01 mm tolerance.

From microporous PE to monolithic TPEE films, each layer is engineered for precise vapor permeability and barrier resistance, forming the foundation for reliable performance.

Core Advantages

•
Uniform Pore Structure: Consistent thickness for reliable MVTR performance.
•
Medical-Grade Surface: Smooth, defect-free surface ideal for hygiene and medical use.
•
High Stability: Chemical and thermal resilience under diverse conditions.
•
Sustainable Process: Solvent-free and low-emission production for a greener planet.

Exceeding global standards by mastering the microscopic details of functional film engineering.

IN-LINE LAMINATION TECHNOLOGY

Seamless Integration
Maximum Efficiency

Kae Hwa enhances its casting process with in-line lamination, enabling immediate bonding right after the film is formed.

This real-time technical approach eliminates intermediate storage and reheating, ensuring stronger adhesion and significantly lower production cost and energy use from film to final fabric.

FAQ

A: Our precision Casting Film Technology ensures consistent film formation with a ±0.01 mm tolerance. As a leading breathable membrane manufacturer, we guarantee uniform pore structure and stable MVTR (Moisture Vapor Transmission Rate) for microporous PE and TPEE films.

A: Yes. Our casting lines produce a smooth, defect-free surface that is ideal for medical and hygiene applications. This ensures that our waterproof breathable films offer high chemical and thermal resilience, fully complying with AAMI and EN medical standards.

A: In-Line Lamination bonds the extruded film directly to non-woven fabrics without intermediate storage or reheating. This “Seamless Integration” significantly lowers production costs and energy consumption while creating high-performance lamination films for industrial and medical use.

A: Absolutely. By bonding right after casting, we achieve stronger adhesion and improved dimensional stability without blocking the micropores. This results in a superior waterproof breathable membrane that remains highly permeable to vapor.

A: Yes. Our advanced 4-Color Printing Technology uses high-resolution rotary systems to apply custom graphics directly onto PE, PP, and TPEE films. We use specialized breathable inks that provide vibrant color consistency without reducing the membrane’s breathability or performance.

A: We integrate our 4-color printing directly with the casting or lamination process, ensuring cost efficiency and lower emissions. Combined with our GRS-certified and ISO 14064-1 carbon management practices, our printed functional films meet strict global sustainability requirements.
