Duplex Board White Back vs. Duplex Board Grey Back: A Comprehensive Comparison
When selecting packaging materials, choosing the right type of duplex board is crucial for both functionality and aesthetics. Two of the most commonly used variants are Duplex Board White Back (WB) and Duplex Board Grey Back (GB). While both offer excellent rigidity and printability, they differ in appearance, composition, and typical applications. This article provides a detailed comparison to help you make an informed decision.
What Is Duplex Board?
Duplex board is a type of paperboard composed of multiple layers, typically with a bleached or coated top surface and an uncoated back. It is widely used in packaging due to its strength, smooth printing surface, and cost-effectiveness.
