After removing the plastic carrier sheet i like to flip my project upside down or inside out and apply some more heat to the backside to ensure a really good application.
Heat transfer vinyl coming off.
So all you need to do is increase the temperature 5 f to 10 f.
It is likely that your heat transfer vinyl is peeling off due to the temperature of your heat press.
Or maybe you could tell that your htv was barely sticking after the press so you weren t all that surprised to notice the heat transfer vinyl coming off but you really wish you understood what went wrong.
I would like to add that you can effectively use a vinyl letter removing solvent in case you want to remove the vinyl from your garment.
Now you should have an idea how to handle heat transfer vinyl peeling off issue.
You are trying to apply your decal to your favorite water bottle and after rubbing it down on your cup for 5 minutes the vinyl will not come off the transfer tape and release onto the cup.
Some types of heat transfer vinyl are cold peel which means you must allow the vinyl to cool completely before removing the clear plastic sheet.
For heat transfer vinyl to work correctly it must be melted into the fabric.
