ALPHANE

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)
