Transparency question

Hi, have what's probably a very basic question about transparency

In the image below, I need the transparent section of the packaging to be a perfectly clear, glossy plastic -- not blurred/foggy as it appears now.

I currently have "Thin-walled" checked -- without it, the bread appears blurred AND distorted. Moving the IOR value down reduces the blur, but then I also lose the glossy highlights.

Any advice would be appreciated, been trying to figure this out for a long time.

The Arnold Standard Material comes with a stock setting that blurs all reflective and refractive rays.

Lowering Roughness from 0.2 to 0.0 will make it sharp.

what shader are you using, and what are the parameter values?
