How to Choose the Right GSM Duplex Board for Cosmetic Boxes
Introduction
Packaging is one of the most crucial elements in the cosmetic industry. A well-designed box not only protects the product but also reflects your brand’s identity and quality. Consumers often make purchasing decisions based on the first impression of a product, and cosmetic boxes play a key role in this perception.
Duplex board is a preferred material for cosmetic packaging due to its versatility, durability, and premium appearance. However, the GSM (grams per square meter) of the board directly influences its strength, rigidity, and cost-effectiveness. Choosing the right GSM ensures that your boxes provide adequate protection while maintaining visual appeal.
With the rising demand for premium cosmetic packaging, understanding the properties, types, and specifications of duplex board for cosmetic boxes is essential. This guide provides a comprehensive overview, selection criteria, and best practices for choosing the perfect board for your products.
What Is a Duplex Board?

A duplex board is a multi-layered paperboard featuring a white-coated front for printing and a natural or grey back for strength. Its name “duplex” comes from its two distinct surfaces: a printable face and a sturdy back.
The manufacturing process involves combining layers of pulp with specific coatings applied to achieve smoothness, rigidity, and printability. Common types include:
• Coated duplex board white back: Both sides coated, ideal for high-end packaging.
• Duplex board grey back: Economical option with a white coated front and grey interior.
• Grey back board: Uncoated grey back with basic printing surface.
• Coated duplex board grey back: Balanced solution offering durability and quality print.
• Kraft back duplex board: Features a brown kraft paper back with a white-coated front and excellent for sustainable or organic cosmetic packaging.
Key properties include:
• Rigidity and stiffness for structural integrity
• Smooth surface for superior printing
• Excellent folding quality for box manufacturing
• Compatibility with embossing, foiling, and die-cutting
Duplex board is widely used not only in cosmetics but also in food packaging, confectionery, and luxury retail products. Adherence to industry standards and certifications ensures consistent quality.
What Does GSM Mean in Duplex Board?
GSM stands for grams per square meter and measures the weight of the paperboard. It directly correlates with thickness, rigidity, and strength.
Typical GSM ranges for duplex board:
• Lightweight: 200–250 GSM, suitable for lipsticks and small products
• Medium weight: 250–350 GSM, ideal for creams and powders
• Heavy weight: 350–450 GSM, best for perfumes and gift sets
• Extra heavy: 450+ GSM, used for premium or multi-product boxes
Choosing the correct GSM is vital to:
• Protect the product from damage
• Maintain structural integrity
• Create a premium feel
• Balance cost and performance
Manufacturers test GSM through calibrated weighing methods, ensuring consistency across batches. Standard tolerance levels maintain reliability and performance.
