CORRUGATED BOARD PROCESS
Corrugated Board Lamination Process
The image illustrates how a coated surface and an offset printed liner are laminated onto a single-face corrugated sheet to create a strong, durable, and visually appealing packaging material. This process is widely used for premium corrugated boxes, retail packaging, and e-commerce shipping cartons.
Coated Surface (Top Layer)
The top layer adds a smooth, protective finish that enhances print quality and improves resistance to moisture, scratches, and handling. It gives the box a premium, branded appearance
Offset Printed Liner (Middle Layer)
This sheet carries high-quality printed graphics, logos, and designs. Offset printing ensures sharp details, consistent colors, and a professional finish—ideal for custom packaging.
Single-Face Corrugated Layer (Bottom Structure)
Made of a fluted medium and inner liner, this layer provides strength and cushioning. It helps the box withstand pressure, stacking, and shipping impacts.
Why It Matters
This process combines structural durability with high-quality print presentation, creating packaging that is strong, protective, and visually impressive. It is essential for brands that require both performance and premium aesthetics in their corrugated packaging.

Corrugated Strength Tests
Understanding Corrugated Strength Tests
Corrugated packaging strength is measured using two key tests: Edge Crush Test (ECT) and Mullen Burst Test. Each evaluates a different performance aspect of corrugated board.
Edge Crush Test – Measuring Stacking & Compression Strength
Measures stacking and compression strength by applying force to the board’s edge.
Higher ECT means better load-bearing and stacking durability.
Common rating: 32 ECT
Mullen Burst Test – Measuring Resistance to Puncture
Measures resistance to puncture by applying pressure to the board’s surface until it bursts.
Indicates linerboard durability and impact resistance.
Example: 200# burst = 200 psi before failure
Why It Matters
ECT is best for stacking strength; Mullen is best for impact resistance—ensuring the right board is chosen for safe shipping.
Color Appearance On Kraft Board
Colors Printing on Natural Kraft Board
When inks are applied directly onto unbleached kraft paper, the natural brown surface absorbs some of the pigment. This can make colors look softer, deeper, and slightly subdued compared to printing on white paper. The result is a warm, organic look that complements eco-friendly or rustic packaging styles.
Color Printing with a White Base Layer
Applying a layer of white ink beneath the printed colors helps them appear brighter and more saturated on kraft material. This method keeps the natural kraft texture visible while dramatically improving color accuracy, offering the best combination of vibrant design and authentic kraft appeal.
White Ink Printing on Kraft Paper
Printing with white ink on kraft paper produces bold, high-contrast graphics that highlight the natural texture of the material. This technique is often used for minimalistic or premium designs, creating a striking visual effect without the need for full-color printing.
