Light weight venting tape
I bought this to use on the bottom openings on double walled poly sheets for my green house. Definitively wide enough. Seems to stick well even with being a light weight. I've seen some that aren't very breathable due to having so much adhesive, I don't think this will be a problem here. I don't think it will just come off either, it will keep bugs and dust out. Easy to work with.

seems to work well to seal bottom of polycarbonate (greenhouse) panels
Seems to work well to seal bottom of polycarbonate (greenhouse) panels. Can tear by hand. Sticks well and should keep out insects and dust from the channels as well as other polycarbonate panel tape.

Great solution to a unique problem.
This is a really neat product. I'm using it on my greenhouse panels to seal up the bottom edge, to keep bugs, dirt and stuff out of the panel. The tape is 1" wide which is just wide enough to leave about 3/8 inch on each side. The tape has enough stick to easy hold and re-position if necessary. The tape tears easily and seems to hold up well during installation. I don't know if it will hold up for the long term but its a great solution to seal up the bottom of the panels. For ease of installation I placed the tape on the open portion of the panel and then folded it over to the two sides. This allows you to lift the tape up and re-position if necessary so that the tape falls evenly on both sides.

shipped by USPS and lost
3M is good product but if you do not have it to use then it is useless. USPS fails at delivery too often!

3M product performs as specified to seal polycarbonate panels
Used this tape to seal the 10mm poly panels in my greenhouse. Product sticks very well and very easy to use on a needed project to prevent dust, bugs water from getting into your panels.

Wouldn’t stick
Purchased this tape to seal a leak around the roof vent in my travel trailer. Read manufacturer’s directions, applied it accordingly, and still leaked. Wouldn’t waste my money again.

Works. But you pay for it.
Needed it to vent my clear roof panels. So far it's working very well. No moisture, no bugs.Update: After a couple year the bugs, dirt and condensation are all there. Too bad it doesn’t last.
