Creating a clear material with no refraction/caustics?

I have a shrink wrap on a bottle and I'd like to not have to create double sided geometry for. Also, being such thin material, it doesn't really need to refract light at all or introduce any caustics. Is there a way to do this in octane?

Specular with index of 1?

unfortunately that gets rid of reflections also. I'm looking for something like the AGS Glass in Maxwell

One trick is to make a Glossy Material (black diffuse, index 1, reflection 1 for a chrome look) then lower the opacity to about 0.2
If you need even more realism, apply a Falloff Map to the reflection/specular amount.
