Polyethylene plastic .055 gauge license plate blanks accept vinyl lettering and graphics well. They are corona treated on both sides for excellent screen printability. These blanks will not accept dye-sublimation. Corona treated means the plastic is treated with a very high electric charge at low voltage. This charge “pits" the surface of the plastic so that it isn’t super smooth. Because of this, it is more receptive to the vinyl adhesive. It is also more receptive to screen printing ink. 10" Round White. Holes are 1/2" from top and 1/2" from bottom.
