Laminating: High-Quality Graphics on Corrugated Packaging

What Is Laminating in Corrugated Packaging?

Laminating is the process of bonding a pre-printed litho sheet — typically produced on an offset press — to the surface of corrugated board. The result is packaging that combines the structural strength of corrugated with the vibrant, photo-quality graphics consumers associate with premium brands. Unlike standard flexographic printing, which prints ink directly onto the corrugated surface, laminating starts with a smooth, coated paper stock that can reproduce fine detail, rich color gradients, and specialty finishes with exceptional clarity.

The lamination adhesive, usually a starch-based or PVA glue, is applied to the corrugated liner before the printed sheet is pressed and bonded under controlled heat and pressure. Proper adhesion is critical: the bond must hold through converting operations like die-cutting, scoring, folding, and gluing without delamination or bubbling.

When Is Laminated Packaging the Right Choice?

Laminating is the go-to solution whenever packaging needs to make a strong visual impression at retail. Common applications include:

• Point-of-purchase displays: Floor stands, counter displays, and endcap units that need to grab shopper attention from a distance. PCG’s PIP division specializes in these high-impact retail solutions.
• Premium product packaging: Electronics, cosmetics, spirits, and gourmet food brands that demand packaging consistent with their brand positioning.
• Club store packaging: Large-format retail-ready trays and shippers sold at warehouse clubs, where the package itself functions as the shelf display.
• Seasonal and promotional packaging: Limited-edition designs where the visual wow factor drives impulse purchases.

If your packaging only needs simple text, barcodes, or single-color branding, direct flexographic printing is more economical. But when your product competes on shelf presence, laminating delivers a level of graphic fidelity that flexo cannot match.

The Laminating Process: Step by Step

Understanding the production sequence helps brands and buyers plan for lead times and design requirements:

1. Litho printing: The graphic design is printed on a flat sheet using offset lithography. This step allows for CMYK process color, spot colors, coatings, and even foil stamping before the sheet ever touches corrugated board.
2. Sheet preparation: Printed sheets are cut to size and inspected for color accuracy and registration.
3. Adhesive application: Glue is applied evenly to the corrugated board’s top liner using a roller system on the laminator.
4. Bonding: The litho sheet is aligned and pressed onto the glued corrugated surface. Precision registration ensures the printed image aligns correctly with the die-cut outline.
5. Curing: The bonded board passes through a drying or curing section to set the adhesive before further converting.
6. Converting: The laminated board is then die-cut, scored, folded, and glued into its final box or display form.

At President Container Group, our integrated manufacturing capabilities mean we control every step — from prototyping through final pack-out — ensuring color consistency and structural integrity across the entire production run.

Laminating vs. Direct Print: Key Differences

Brands often ask us when laminating justifies its additional cost over standard corrugated printing. Here is a straightforward comparison:

• Print quality: Laminating reproduces photographic images, fine gradients, and metallic effects. Flexo printing works best for solid colors, line art, and simpler graphics.
• Surface finish: Laminated packaging can feature gloss, matte, soft-touch, or spot UV coatings. Flexo-printed corrugated has a more utilitarian appearance.
• Cost: Laminating involves an additional litho print run and the lamination step itself, increasing per-unit cost. For high-volume commodity shipping boxes, direct print is more economical.
• Lead time: The extra production steps add time. Planning ahead with your packaging partner is important.

Our team at President Container helps customers evaluate these trade-offs early in the design process so that every project hits the right balance of visual impact and budget.
