Should I use an iron-on patch on a bag made out of polypropylene fibers?

My auntie gave me this tote bag for Christmas, and I want to put a iron-on patch on it. This is my first time owning a bag made out of polypropylene fibers, so will my bag burn/melt if I try to put the patch on, or is it safe for me to put it? Thanks in advance!
