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 *Reduction rate of 99% compared with general PP films (both figures based on comparison with company products) |
|
The number of fish-eyes was reduced by 90% compared with the ALPHAN E-201 series, and the average size of the fish-eyes also decreased (comparison with company products; reference figures). |

|
By not using anti-blocking and other additives, the ALPHAN E-201 series features superior surface properties with minimal unevenness.
|
Leveraging the surface inertness properties of polypropylene films, the product can be used as a release film with low pollution risk to the adherend.
