Abstract
A method of making an identification card by advancing a continuous web having a first side and a second side along a predetermined path and coating a first portion of the first side with a release agent. The first portion and a second portion of the first side are then coated with a pressure sensitive adhesive, the second portion being adjacent to the first portion and about the same size as the first portion. Next, a sheet of clear plastic is adhered to the adhesive so that the plastic overlays the first and second portions. The plastic sheet and the web are then perforated or die cut around the outer periphery of the first and second portions. The web is also perforated or die cut between the first and second portions. Next, only the first portion of the web is then removed from the plastic sheet and the second portion of the web to expose one-half of the plastic sheet and the adhesive thereon while maintaining the entire second portion with the plastic sheet. The exposed half of the plastic sheet is then folded over the second portion and adhered to the second side of the second portion.
