*We will consider processing the thickness of base films other than the above.


We manufacture in a Class 1000 clean environment from coater to finishing, and continuously supply products with reliable quality. The 3-head multi-coater at the Oji F-Tex Shiga Mill can  carry out static prevention and coloring processing at the same time as release processing (maximum product width: 1,600mm).

Release processing

In our ordinary release film using silicone as a release agent, we have a wide-ranging lineup available, from ultra-light release grade with very light release, to heavy release grade (release strength: 40 - 700mN / 30mm). Meanwhile, for purposes where silicone transfer should be avoided, we also provide products made with non silicone-based release agents.

We also handle coating other than release agents using clean coaters, and will consider individual requests. Besides release film, Oji F-Tex also has a full range of release papers based on glassine paper and wood-free paper, and would be glad to advise in response to your inquiry.
