Canon Clear Backcoat Film

I notice a lot of Canons inkjet supplies are basically repackaged product from other manufacturers. Has anyone seen their Clear Backcoat Film to see how it compares to OHP?

They also have a 'white glossy film' - wonder how this might stack up against the pictorico PGHG White Film?
