Product Overview: A White Film with Medium Transparency
Our TPU Breathable Membrane is a white film with medium transparency. Its transparency level sits between our low-transparency white and high-transparency white films. We refer to it as medium-transparency white matte PH.
The white color of this film is very pure. It is neither greyish nor bluish, but a clean and consistent white tone. This helps light-colored garments achieve a more refined and high-end appearance.
This TPU Breathable Membrane provides both strong waterproof performance and excellent breathability. It is an ideal choice for light-colored outdoor apparel that requires both protection and comfort.

Why Choose This Film: Blocks Backing Color for Clean Looks
Our TPU Breathable Membrane effectively blocks the color of backing fabrics. When producing light-colored down jackets, dark backing materials can show through and negatively affect appearance. This white film prevents that issue, ensuring a clean and uniform final look.
It is widely used in white, beige, and light grey garments. Our white masterbatch is developed in-house and is not available on the open market. We control the formulation in our laboratory to ensure consistent color quality, with no black specks or color variation.
Customers who place large-volume orders consistently report excellent color stability, with strong consistency between different production batches.
