  • Patent number: 5720384
    Abstract: An improvement of laser record protection folder over U.S. Pat. No. 5,501,326. There is a rectangular shape bag element for holding either a laser record or an index printing. A "Y"-shape dividing line and a slot opening are formed in one of the two pieces of the bag element to facilitate the insertion or removal of the laser record or index printing. The dividing line forms a sealed envelope on the bag element and thus can prevent the recording surface of the laser record from smearing by user's hand or ambient dust and dirt.
