What is the heat resistance of Shrink-Art Films? Well, it’s fairly low, compared with other films like our DuraLar TM films. It’s even a little less heat resistant than our ClearLay TM Rigid PVC and our acetate film. But that’s a good thing! The whole point of Shrink-Art film is to bake it in an oven and watch it shrink. For more information on using our Shrink-Art film, please review the usage instructions on the product page.
