Well, first of all we call them "snap" bags here in Virginia but it's the same thing. I bought a 3/4" tape in the Dollar Store and it was so flimsy that I had to double it. So I guess it's up to you as to how strong you want it to be and how much money you want to spend on your tape measure. If your tape is so stiff that you can hardly open your bag, perhaps you bought a tape that is "too good" to be used in bags - like a carpenter quality tape?
