Standard A4 Size, Ready to Use

No measuring, no cutting. Every pad in the pack is pre-cut to exact 297 x 210mm (A4) — consistent sizing with clean edges and square corners. Use as rigid inserts inside A4 mailers, protective layers between stacked items, or backing boards behind prints and photographs.

4mm Kraft Brown Corrugated Board

4mm thickness provides medium rigidity — a step up in stiffness for heavier items and applications where the pad needs to hold its shape under load. Available across multiple thicknesses to match your application.
