What Kinda Bike Is That?
If you haven't already done this, I suggest removing the center, "molding point", (is this called a 'sprue riser'?), inside your luggage. By leaving it, you will risk that it will chafe a hole in something. I have cut mine off with a hacksaw blade after I found some "rubbing" marks on some map books I was carrying and a small hole in my tent stuff sack.
