    INFINITY® is a clean, recyclable, 100% styrene foamboard with 2.5x more density, 22% less weight and 3D cold bend capability.

    INFINITY® features a super-smooth styrene surface eliminating pre-production cleaning and preparation which increases printing speed and efficiency.

  • Insite® Reveal®

    Insite® Reveal® features smooth, bright white paper manufactured with a moisture resistant clay-coating for superior ink coverage and exceptional color gloss. For mounting applications, the coating also acts as a barrier that minimizes adhesive absorption while maximizing mounting and laminating speeds when using a roll laminator.

  • MountCor®

    MountCor® offers the lowest bonding temperature of any heat activated board available. Its specially formulated neutral pH adhesive is stable, inert and has revolutionized the industry with its dependable 130°F (54°C) low temperature/short dwell bond time in mount presses.


    EAGLECELL™ is a recyclable, all-paper honeycomb graphics board with triple-thick bright white clay coated liners manufactured with 100% fully recyclable paper core and surface papers.
