Anime-Beta TNG

Lately, I can't find bags large enough for backgrounds and have had to resort to piecing together bags for odd sized items. Has anyone used polypropylene tape to piece together cel bags or anything artwork related?

I generally try to stay away from taping bags because I've seen the damage it can do to douga and genga. I know that cellophane tape (scotch tape) is acidic, and would likely, over time, have some sort of reaction with the bags. I'm hoping since both the bags and the tape are the same material that that will no longer be an issue.

For oversized arts that can't fit the bag standards, I use a 60" width polypropylen roll. Tape is one of the restaurator enemies !

I use "Scrapbooking tape" by Scotch to baste together cel bags. It is rated acid-free, and it goes on the outside, not the inside just in case.

For repairs directly to sketches or backgrounds, I use Neschen Filmoplast P mending tape, which is buffered with CaCO3 and is rated archivally stable for long-term storage of paper products. It's expensive but as I use tiny strips the 50m roll will last nearly as long as I do.
