What Is Greyboard? A Complete Guide to This Sustainable Packaging Material
Greyboard is a rigid paperboard produced from 100% recycled fibres without bleaching or dyes. It ranges from 0.8–4 mm thick, with strength determined by board density and layer lamination using starch-based glue. The material’s stability and recyclability make it common in rigid boxes, bookbinding, and premium packaging. Automated pasting and die-cutting provide consistent tolerances for precise assembly. Its low energy production and full recyclability support FSC and ISO environmental compliance.
