Grey board, also called grey chipboard, is a rigid, uncoated paperboard widely used in packaging and binding. Made mainly from 80–100% recycled waste paper pulp, it gets its natural grey color from raw materials and is produced by pressing multiple pulp layers-distinguishing it from coated boards like white cardboard or blister board (note: grey board has no blister adhesion properties).
Common types include single grey (grey on one side), double grey (grey on both sides), and full grey (uniform grey), each for different uses. Its core advantages make it a top choice for global manufacturers and buyers.
First, it boasts excellent stiffness and compression resistance. The multi-layer pressing process gives it high rigidity, so it won't bend or break easily-perfect for hardcover book covers, gift box frames, shoe box liners, and photo frame backings, protecting products during transport.
Second, it's eco-friendly and cost-effective. Recycled pulp reduces waste and production costs, aligning with global sustainability trends while offering a budget-friendly solution for bulk buyers.
Third, it's versatile. Available in grammages from 200 to 1500 g/m² and thicknesses from 0.3 to 5 mm, it can be customized. Its smooth, uniform surface suits simple printing or laminating for various packaging needs.
Finally, it's easy to process-cut, fold, glue, or punch with basic equipment, adapting to custom sizes and designs. Proper moisture-proof packaging ensures it maintains quality in humid conditions or during rainy weather.
In short, grey board is a reliable, sustainable, and cost-effective material for structural support and packaging. For businesses seeking a versatile, budget-friendly option, it's an unbeatable choice.
