  • Patent number: 6126013
    Abstract: An embossed plastic sheet material is molded to have a relief image with a peripheral edge that is formed by a partial shearing of the material of the plastic sheet near or at the peripheral edge so that the image lasts longer and does not relax or deteriorate naturally or with repeated and prolonged use. Also disclosed is a protective container made from the embossed plastic sheet material that can be used in a carrying case and an album to safely store and transport valuable and collectible items including coins, bottle tops, pogs, optical disks, magnetic disks, audio and video disks and tapes, stamps, photographs, match books, and other similar items. An embossing roller assembly is also described that can be used to fabricate the embossed plastic sheet material.
