Power/volume buttons tape over disk

While replacing the battery on a Samsung Galaxy Note 10.1 2014 Edition the disk fell off the power contacts. I held it in place with a corner of tape from over the battery plug. This worked well. My question, The factory style tape over the buttons has to be available somewhere. I'm unsure of what the proper name may be and as it is not specific to certain models of phones or tablets where would I search.

Thanks for the info in advance.

Here is a photo from an ifixit teardown that shows the buttons.
