What Is Greyboard?

What greyboard does

Greyboard is a dense recycled paperboard used as the structural core of many rigid boxes, slipcases and presentation packs. It is normally hidden beneath a printed wrap, specialty paper or lining.

Its role is stiffness and shape retention, not direct high-resolution printing.

Thickness and box engineering

The suitable board thickness depends on box size, product weight, opening style and the width of unsupported panels. More thickness is not automatically better because it also affects folds, wrapping and shipping weight.

Large lids, magnetic closures and heavy inserts should be evaluated as a complete structure rather than as isolated board specifications.

Wrapping and quality checks

The wrap paper determines most of the visible color, texture and print quality. Grain direction, corner wrapping and adhesive control affect whether the finished box stays flat and clean.

Approve board thickness, finished dimensions, corner appearance, lid fit, warping and wrapped-surface scuff resistance before mass production.

Sample and approval checkpoints

Use a structural sample to verify size and fit, then a printed sample when color, material and finishing need approval. Record the accepted specification so production is checked against the same reference.

• Confirm dimensions and product fit
• Approve material, print color and finishing
• Confirm packing method and master-carton details
• Keep one approved reference for production QC

Information to send for quotation

A useful inquiry gives the supplier enough information to recommend a realistic structure and production route.

• Product dimensions, weight and reference photos
• Target quantity and expected reorder plan
• Artwork status, colors and required finishes
• Delivery country, target date and confirmed compliance notes
