Re: strong tape of 0.15 to 0.20 mm thickness

Ryuji,

You might try aluminum tape. I don't know the thickness, but it's very 
strong and the surface is both flat and low friction. It also adheres to 
itself if you need a second layer.

About ten years ago, I decided to insulate my heater ducts. This is the 
tape I was instructed to use. It's still there. You can buy it at any of 
the big box home improvement places.
