LOOKING FOR THICK FLEXIBLE PLASTIC SHEETING?

I NEED TO MAKE A TORSO MANNEQUIN FORM FOR A POLE MOUNT APPLICATION TO DRAPE A MILITARY JACKET OVER AND WAS CONSIDERING AN UNKNOWN FLEXIBLE PLASTIC SHEET THAT I COULD ROLL AND WOULD HOLD ITS OWN SHAPE WHEN RIVETED. IT WOULD BE NICE IF IT DID NOT GIVE OFF A VAPOR THAT WOULD HARM THE FABRIC OVER TIMELOOKING FOR THICK FLEXIBLE PLASTIC SHEETING?
Have you tried Home Depot or JoAnn Fabric? Both sell different mil thicknesses of sheeting.
