Duplex vs Kraft Corrugated Box
Difference, Uses & Cost Comparison
Published by ProPac Tools | Packaging Solutions Blog
When it comes to packaging, choosing the right type of corrugated box can make a significant difference — in product protection, brand presentation, shipping costs, and sustainability. Two of the most commonly used options are Duplex Board Corrugated Boxes and Brown Paper (Kraft) Corrugated Boxes.
While they may look similar at first glance, they serve different purposes and perform differently under various conditions. In this guide, we break down everything you need to know — difference, uses, and cost comparison — to make the right choice for your business.
What Is a Duplex Board Corrugated Box?

A Duplex Board Corrugated Box is made using duplex board — a two-layered paperboard that features a white or grey coated surface combined with a corrugated flute inner layer for structural strength. The smooth outer surface is ideal for printing high-quality graphics, logos, and brand designs.
✓ Key Characteristics:
- Smooth white or grey coated outer surface
- Excellent printability — vibrant colors, logos, and custom designs
- Lightweight yet sturdy construction
- Ideal for retail-ready or consumer-facing packaging
- Available in single-wall and double-wall corrugated structures
- Superior print quality
- High brand visibility
- Premium look & feel
- Great unboxing experience
- More expensive than Kraft
- Less tough for very heavy loads
- Requires coating process
What Is a Brown Paper (Kraft) Corrugated Box?

A Brown Paper Corrugated Box — also called a Kraft corrugated box — is the classic packaging workhorse. Made from unbleached Kraft paper, these boxes are known for their raw strength, durability, and cost-effectiveness. They are the standard choice for shipping, warehousing, and industrial applications worldwide.
✓ Key Characteristics:
- Natural brown Kraft paper surface
- High tensile strength and tear resistance
- Widely available and cost-effective
- Suitable for heavy-duty shipping and storage
- Available in single, double, and triple-wall flutes
- Very high burst strength
- Budget-friendly at scale
- Great for heavy & bulk goods
- Most eco-friendly option
- Limited print quality
- No premium retail look
- Less suited for D2C branding

Common Uses & Applications
Duplex Board Box — Best Uses:
- Retail & E-commerce Packaging — When the box goes directly to the customer
- Food & Beverage — Attractive packaging that makes products look premium
- Cosmetics & Personal Care — Stunning unboxing experience for beauty brands
- Electronics Consumer Packaging — Smartphones, accessories, gadgets
- Gift Boxes & Premium Packaging — Special occasions and luxury products
Brown Kraft Box — Best Uses:
- Industrial Shipping & Logistics — Long-distance, heavy shipments
- Warehousing & Storage — Durable solution for bulk storage
- Appliances & Heavy Goods — Where high burst strength is needed
- Agricultural Produce — Farm to market packaging
- Wholesale & Bulk Distribution — Cost-efficient large-scale packaging
Cost Comparison
Duplex Board Box: Generally more expensive due to the white coated surface and printing-ready finish. The added cost is fully justified when brand visibility and premium unboxing experience are priorities for your business.
Brown Kraft Box: More economical and widely available. For businesses focused on bulk shipping, warehousing, and operational efficiency, brown corrugated boxes offer excellent value for money — especially at large scale.
Environmental Considerations
Both types are recyclable and can be manufactured from recycled content — far more sustainable than plastic alternatives. Brown Kraft is generally seen as the greener option due to its unbleached natural composition. Duplex board, while recyclable, goes through additional coating and bleaching processes.
Which Box Should You Choose?
- ✓ Choose Duplex Board Box if: brand presentation matters, you sell directly to consumers, need high-quality printing, or want a premium unboxing experience.
- ✓ Choose Brown Kraft Box if: you prioritize shipping strength, cost savings, heavy-load capacity, or packaging for industrial/bulk distribution.
- ✓ Use Both: Duplex board for outer retail packaging + Brown Kraft for inner shipping cartons — the smartest approach!
