Release Films

Kern Release Films are engineered by applying single or dual-sided release coatings, including silicone, fluorine-based, and silicone-free release agents, onto a variety of substrates such as PET, PO, and PI. These films are widely used in the production, manufacturing, and die-cutting processes of various adhesive tapes and labels.
With our ability to ensure stable release force and high residual adhesion rate control, Kern leads the technological trends in release film solutions. From release formulation to full-process coating production, every step is strictly monitored to guarantee consistent release force, cleanliness, and performance across every roll of film.
Our products comply with RoHS, REACH, and other regulatory standards, offering eco-friendly options such as halogen-free alternatives.

Silicone Release Film
Utilizing silicone release agents, these films can be produced with a wide range of release forces (1–1500 gf/in) and are available on various substrates. They exhibit excellent UV resistance and durability against atmospheric exposure, making them ideal for the production and die-cutting of electronic tapes and labels. Notably, ultra-light release force variants maintain high residual adhesion while ensuring easy release.

Fluorine-Based Release Film
These films employ fluorine-based release agents and are primarily used in the production and die-cutting of silicone tape products. Kern has developed high-performance fluorine-based release films specifically for direct coating applications involving high-adhesion silicone materials (such as silicone gels and silicone OCA).

Silicone-Free Release Film
These films use specialized fluorine-free and silicone-free release agents. For instance, the release force for tesa 7475 tape can be tailored to 40–2000 g. They are mainly applied in industries sensitive to fluorine and silicone, such as semiconductor packaging and electronic components.

Embossed Release Film
Kern’s ultra-fine UV embossed release films feature stable texture structures and are suitable for direct coating tape applications. Their ultra-light release force variants offer excellent air release properties, making them ideal for production processes involving OLED screen SCF structural tapes, as well as highly sensitive materials like copper/aluminum foils and graphite sheets.
