What is a duplex business card?

A duplex business card is a thick card created by laminating two separate sheets of paper back-to-back. You typically use this method to achieve a specific total thickness that exceeds the standard single-stock limit, or to combine two different paper stocks in a single card. For example, you might pair a heavy uncoated stock with a lighter coated stock to create a distinct tactile difference between the front and back. This lamination process results in a card that feels substantial and durable in your hand. The final product remains flat and rigid, offering a premium alternative to standard single-sheet cards without requiring exotic paper weights.
