Heat Resistant Tape 10mm & 20mm
 
B's Glitter World heat resistant tape is temperature rated for 300+degrees.
It’s main purpose is to secure the sublimation paper on the blank while in a press or oven/air fryer. 
It also keeps the sublimation paper from moving when the blank is removed and cooled. If the printed sublimation paper was to move or slide during any part of the process, it will cause a ghost image and your product would be non saleable.
