non flavored (plain) pectin from the canning section of the grocery store works perfect for wrapper repairs. Watch for flavoring agents (e.g., read the ingredients list).

I find glue sticks work great for about 2-3 weeks for me, so I tend to add a very small piece of transparent tape as well. Harder to get off, but I don't make the bands especially tight so that I can tear them off easier.
