10. FAQ — Duplex Board Technical FAQ

Q1: What is the typical composition of duplex board?
A: Duplex board consists of two layers: a bleached (white) top layer for printing and a grey/white recycled fiber backside, often enhanced with kaolin or calcium carbonate coatings for sheet smoothness.

Q2: How is grammage (GSM) different from caliper?
A: Grammage (GSM) measures the mass per square meter (bulk/density), while caliper refers to the actual thickness. Higher GSM generally increases stiffness but caliper impacts feel.

Q3: What are the recommended moisture control standards?
A: For duplex board, moisture content should remain at 7.5% ±1% to avoid curling. Standards: ISO 287, TAPPI T412.

Q4: Can duplex board be used for direct food contact?
A: Only food-grade, FDA/EC-certified grades may be used for direct contact; most are for secondary/outer packaging with functional coatings.

Q5: What printing techniques perform best?
A: Offset, digital, and flexo printing are preferred, especially with double coated duplex board for high-resolution graphics.

Q6: How does duplex board compare to virgin SBS board?
A: SBS (Solid Bleached Sulphate) is fully virgin fiber with higher brightness and purity; duplex board is more eco-friendly, cost-effective, and offers sufficient print quality for most packaging.

Q7: What is the typical sheet size for industrial orders?
A: Standard: 787x1092mm, 889x1194mm; custom: up to 1200x1200mm. Rolls also available for converting.
