Are you exhausting this shed or using an AC. If your exhausting the shed there will be negative pressure and therefore needs to hold better. I have used Ferring strips, painted white, in several rooms to hold up the panda film when negative pressure is present with no issue.
if you don’t have exhaust fans I guess tape might work, but I’d be afraid of it falling down mid run, not all places are easy to get to and fix while plants are in a room. Also you don’t want the plastic to potentially pull lose and land on either something hot (grow light) or on your plants.
