ALPHAN High-Grade Types（Industrial Use）Biaxially Oriented

Even Higher Purity— the Advanced Alphan
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.
Characteristics of
ALPHAN High-Grade Types
ALPHAN High-Grade Type Series
It’ s common for OPP films to include such additives as
anti-blocking and anti-static agents in order to enhance
E-201F
functionality. In the electric materials field, however, 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. With their

properties, and there are also new easy-release types with
improved releasability available to meet diverse customer
requirements.

General packaging film
Ultra-thin type
ALPHAN EM-501
This ultra-thin film maintains OPP qualities while pushing the bounds of thinness. The film has handling properties that make
it applicable for capacitor manufacturing processes. Standard thickness ranges from 4~15µｍ (thinner grades are also
available).
Highly smooth surface type
ALPHAN 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 small protrusions not only prevents defects and problems with
appearance, but also transfer-related problems.
Fish-eye less type
ALPHAN FG-201
NEW
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
ALPHAN MA-411, 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.
Easy-release type
ALPHAN ER-440
NEW
Although OPP films are designed to have release properties, this film further improves releasability. This new film reduces the
peel force of the adherend by about 20% compared with ALPHAN E-201F, expanding the possible combined applications with
adhesive materials.

Biaxially Oriented Polypropylene Films
Fish - eye less OPP Film
ALPHAN FG - 201
With their high smoothness, Oji F-Tex’s ALPHAN
E-201 series polypropylene films have become
popular with a large number of customers. The
fish-eye less OPP film ALPHAN FG-201 was
developed and commercialized as an advanced series
to meet customer requirements for polypropylene
films with reduced optical defects and higher surface
smoothness. Compared with the ALPHAN E-201
series, the ALPHAN FG-201 reduces fish-eye defects
by about 90%* through advanced screening
technology to reduce minute contamination,
enhanced purity of resin raw materials, and improved
process cleaning.
*Reduction rate of 99% compared with general
PP films (both figures based on comparison
with company products)

customers as release films for various applications. Oji F-Tex has
responded to customer requirements for light peel force films with
the development of easy-release type film* ALPHAN ER-440 series.

When the adhesive force of the adherend is strong, the easy-release layer is rarely destroyed.
2 Non-pollutive
Since the ALPHAN ER-440 does not use anti-blocking agents, the amount of unevenness is low. Additionally, since there
are no release agents coated on the film, the ALPHAN ER-440 can be used as a low pollution risk film in terms of
transferring release additives.
