Greyboard Packaging in Bridgeport, CT

Greyboard is high-density compressed paperboard manufactured specifically for luxury rigid set-up box construction -- the premium specification within the chipboard family that delivers the weight, rigidity, and dimensional consistency that luxury packaging requires. Produced from compressed recycled paper fiber at densities typically ranging from 900 to 1400 kg/m3, greyboard at standard rigid box thicknesses (1.5mm to 3.0mm) creates boxes with the substantial physical presence that communicates premium quality through the sense of touch before any visual element is evaluated.

Greyboard vs. Standard Chipboard

The distinction between greyboard and standard chipboard in packaging specifications is density and quality control. Greyboard is manufactured to tighter density tolerances, tighter caliper tolerances (typically plus or minus 0.1mm versus plus or minus 0.3mm for standard chipboard), and with more consistent internal structure that minimizes the surface irregularities that can telegraph through thin wrap papers. These tighter specifications produce boxes whose surface is flat enough for even thin specialty wrap papers (Japanese tissue, fine linen texture) to adhere and display without surface imperfections appearing through the wrap.

Greyboard Thickness Standards

Standard greyboard thicknesses for luxury rigid box construction are 1.5mm, 2.0mm, 2.5mm, and 3.0mm. The appropriate thickness is selected based on the box dimensions, product weight, and the premium tier the brand requires. Larger boxes require thicker greyboard to maintain adequate corner rigidity at the extended wall lengths. Heavier products require thicker base panels to maintain flatness under product weight. Premium tier brands specify thicker greyboard to communicate quality through the box's weight and rigidity.
