Corrugated Packaging 101: Strength, Sustainability, and Customization

Corrugated Packaging 101: The Backbone of Food, Beverage & Nutraceutical Shipping

Corrugated packaging isn’t just a shipping box; it’s an important part of your product’s journey from production to shelf. As industries evolve to meet sustainability goals and customer expectations, corrugated packaging continues to lead in performance, customization, and environmental responsibility.

Whether you're a food producer, beverage brand, or nutraceutical company, understanding the benefits of corrugated packaging can help you make smarter, greener decisions. In this blog, we’ll cover what corrugated packaging is, why it matters, and how to leverage it for success.

What is Corrugated Packaging?

Corrugated packaging consists of a fluted corrugated sheet sandwiched between two linerboards. This layered structure provides exceptional strength, shock absorption, and durability. It’s not to be confused with cardboard, which is typically a single-layer paperboard.

Corrugated materials are used in:

• Shipping boxes

• Retail displays

• Product trays

• Custom-fit packaging inserts

They come in various flute sizes and wall types (single, double, or triple wall), offering flexibility based on your product’s weight and fragility.

Why Corrugated is the Packaging Industry Standard

There are several reasons why corrugated packaging continues to set the benchmark for strength, versatility, and eco-conscious performance across a wide range of industries.

1. Strength & Durability

Corrugated boxes are built to withstand compression, moisture, and impact. This makes them ideal for heavy, perishable, or fragile products.

2. Sustainability

Corrugated packaging is made from renewable resources and is 100% recyclable. Many boxes also contain recycled content, making them an environmentally friendly choice.

3. Cost-Effective Protection

They offer superior product protection at a low material cost, reducing damage-related returns or spoilage during transport.

4. Customization & Branding

Corrugate is easy to print on and shape to fit your product perfectly. With print options ranging from high-end litho to flexo to full-colour digital, the opportunities to brand your boxes and trays are vast.

5. Lightweight & Efficient

Compared to wood or rigid plastics, corrugate is lighter, which can lower your shipping costs and carbon footprint.

Industry-Specific Uses for Corrugated Packaging

Corrugated packaging adapts to the unique needs of each industry, offering tailored solutions that balance protection, presentation, and sustainability.

Design Options for Corrugated Boxes

Customization doesn’t stop at the box size. You can customize your corrugated packaging with:

• Printing Methods: Flexographic, digital, or lithographic printing

• Coatings & Laminates: For moisture resistance or a premium look

• Die-Cut Windows & Handles: Added function and shelf appeal

• Sustainability Certifications: FSC-certified or post-consumer content

This flexibility allows brands to align packaging with their image, product needs, and environmental goals.

Common Corrugated Box Styles

Choosing the right box style ensures your product is protected, presented well, and delivered efficiently at every stage of the supply chain.

• Regular Slotted Container (RSC): Standard shipping box

• Full Overlap (FOL): Extra strength for heavy items

• Tray & Lid Sets: Great for in-store displays or promotional items

• Die-Cut Boxes: Custom shapes and opening styles

Selecting the right style depends on how your product is shipped, displayed, and handled by the end user.

Sustainability Spotlight: Corrugated’s Green Advantage

Corrugated packaging stands out as a leader in sustainable materials, offering brands a responsible solution that aligns with environmental initiatives and consumer expectations.

• Renewable Material: Made mostly from trees harvested responsibly

• Recyclability: Easily recyclable through curbside programs

• Recycled Content: Many boxes are produced with up to 100% recycled fibre

Using corrugated packaging helps businesses meet environmental goals without sacrificing strength or design.
