Polypropylene Bags

[Johnellisimages]

Hi,
I'm trying to find out if it's possible to sublimate on Non Woven Polypropylene shopper/tote bags? I Can't seem to find anything on here about them. Just wondering if it's pretty much the same as polyester or is it going to melt in my press. I'll call the supplier tomorrow for info but thought I would ask in case anyone has experience with these.

Thank you in advance
