Homogeneous type of Anti-Static transparent PVC film is made of anti-static compounded PVC not anti-static coated material. This homogeneous PVC film is all anti-static on both sides and ESD control properties rement perment. 

This shows volume resistivity as well as sureface resistivity because of homogeneous anti-static construction.

The surface resistivity is 10e8 - 10e10 ohms/sq and the volume resistivity is 10e7 - 10e8 ohms.
