To the OP, I've wondered the same thing. The only thing that should be addressed is the punched hole. I'm sure that there are easier ways to do this, but my method is to cut a small piece of tin foil to cover the hole, then wrap tape around it all. This way, I don't have to worry about adhesive getting into the cargo (they can get pretty hot). Once the punched hole is "patched", the carto is no different than a non-punched one. If you have a hole puncher (for paper), use it to punch out a small circle of foil. Adhere the foil to tape of your choice, and wrap over the hole.
Problem solved. No juice leaking out of the punch, and no losing sleep over wondering if the tape is bad for the juice/ filler.
Just my method. Hope this helps!
