I use newspaper with my BP and have the same issue with him crumpling it up. I don't really worry about it... it still does the job of absorbing waste, which is the reason it's there at all. No adhesives at all... I am unaware of any that will not cause damage as above.
TBH, if that were my animal, I'd be making an appointment with my herp vet. Just mainly to make sure that I was caring for the wound properly. It's a pretty big open wound area... may just look worse than it is, but
I would want a veterinary professional's opinion in case. Poor snakey.
