ALPHANE

ALPHAN is a biaxially oriented polypropylene film from OJI F-Tex. The new ALPHAN High-Grade Types are based on capacitor OPP film technology and are ideal as release films for electric and electronic materials, which are rapidly evolving, and for such special industrial applications as cover films for manufacturing processes. Oji F-Tex provides OPP films with corona treatment, specially processed surfaces and other specifications to meet the needs of its customers.

アルファンハイグレードタイプの特徴

It's common for OPP films to include such additives as anti-blocking and anti-static agents in order to enhance functionality. In the electric materials field, owever, these additives can interfere with the electric materials’ functions.
For this reason, customers require functional films that offer low pollution risk for the electric materials.

Oji F-Tex has developed the ALPHAN High-Grade Types with a minimal amount of additives. Utilizing the surface inertness properties of polypropylene films, the High-Grade Types can be used as release films without the use of a release additive coating.

The new High-Grade Types include an ultra-thin type, a variable surface type (from highly smooth surfaces to high mat-tone surfaces), and a fish-eye less type which prevents defects caused by fine surface protrusions.

Ultra-thin type

↑Page Top

アルファンEM-501

This ultra-thin film maintains OPP qualities while pushing the bounds of thinness. The film has handling operties that make it applicable for capacitor manufacturing processes. Standard thickness ranges from 4~15μ m thinner grades are also available).

Highly smooth surface type

アルファンE-201F

This highly transparent OPP film has a highly smooth surface featuring minimal amount of anti-blocking agents and small protrusions causing fish-eye defects. The minimization of sm all protrusions not only prevents defects and problems with appearance, but also transfer-related problems.

Fish-eye less type

アルファンFG-201

Compared with previous High-Grade Types, this OPP film raises the standard for reducing fish-eye defects. This type is ideal for applications requiring high-quality appearance and surface properties.

Mat-tone type

アルファンMA411、MA-420、MAM-430

This OPP film features an uneven mat-tone surface produced without additives or secondary processing. The film comes in a wide range of specifications, from a fine roughness to ultra-high roughness. The range is differentiated by both appearance and function.
For example, the film surface qualities can be transferred to carrier surfaces, while the friction coefficients can also be controlled.
