Sticker backing

I love the quality of the clear sticker I ordered and maybe I was supposed to order a different one, the issue is the backing on the sticker. It's almost impossible to get off. Unless you get lucky and catch the corner. Do you have clear labels that come on a roll?? I am using these to label my coffee cups in my coffee shop and they do look adorable, however It's going to take me hours to get a task done that could have been very simple and quick.
