Mylar - The stuff that makes your buttons shiny! February 22 2013
Side view of a stack of Mylar for button making. That stack will make about 1000 pin-back buttons. Mylar is available in 2ml & 3ml
The plastic glossy cover on a button is actually made from mylar. Mylar is quite durable, strong, has a high tensile strength so it is ideal for holding buttons together. The mylar goes over the image to seal the button.
