Duplex cartons have become one of the most widely used packaging formats for FMCG, cosmetics, pharmaceuticals, household items, snacks, and retail goods. Offering a unique balance of strength, print quality, and cost efficiency, duplex packaging is the ideal choice for brands that need attractive yet budget-friendly packaging.
With advanced printing and converting capabilities, manufacturers like Kardboards deliver duplex cartons that support branding, product safety, and high-volume production needs.
What Are Duplex Cartons?
Duplex cartons are made from duplex board, a two-layer paperboard material featuring:
- Outer white-coated layer for high-quality printing
- Inner grey or recycled layer for added strength and affordability
They are lightweight, customizable, and ideal for packaging consumer goods that require strong visual presentation.
Why it matters: Duplex board offers premium print clarity at a fraction of the cost of solid bleached board (SBS).
