    Alternate names
    Cor-X®, PolyFlute®, Corulite®

    A tough, rigid, inert and chemically stable corrugated plastic made from a copolymer of polypropylene and polyethylene. Resistant to water, oils and solvents. Can be die cut, sawn, scored, folded, drilled, stapled, spot/heat welded, glued, or fixed with nails or screws. Unlike blueboard it will not provide hygroscopic buffering.

    Commonly available in 30 x 40, 40 x 60 and 48 x 96 sheets; 3mm, 4mm, 6mm and 10mm thicknesses. In museum applications either translucent "natural" colored or white is typically used. In thinner thicknesses it can be die cut to make folding tab boxes and trays. Also available in a variety of pre-fabricated storage boxes. Custom sizes (longer) available by special order.


    Often used in storage applications as an alternative to acid free corrugated cardboard (‘blueboard’). Can be formed into boxes suitable for storage and transit. It is an excellent backing material for paintings and framed works on paper providing a valuable alternative to conventional foam core or blueboard. Due to its water and puncture resistant qualities, is also used to cover the open space in transit frames and hybrid crates.
