This tape sticks very well to poly sheeting used for vapor barrier. I recommend sharp scissors as this product is thick/strong. I bought another brand to finish the project and it did not compare in durability or adhesion.

Sticky and a bit stretchy (not quite as stretchy as electrical tape, and definitely a bit thinner). Worked great for my crawl space encapsulation. I would highly recommend this tape!

This adhered cleanly and is surprisingly strong. We were impressed with how good it was compared to the Tuck tape that we usually use. This tape is very wide, even wider than we needed it to be, which makes it very easy to use if a little excessive at times.
