If you've ever shopped for packaging, you've probably thought that boxes are made from the same material. While “cardboard” is often used as a general term for paper-based packaging, you'll also come across corrugated board and paperboard. These materials are made differently and offer distinct advantages for different packaging needs.
So, what does all this mean when you’re choosing packaging? This NextDayFlyers guide walks you through the key differences, explains how each material’s features affect packaging performance, and highlights the best uses for each type. By the end, you’ll know which material best suits shipping, retail packaging, or your unique product needs.
What is Corrugated Board?
Corrugated board, also known as corrugated fiberboard, is a durable paper-based packaging material made from flat sheets called linerboards and a central fluted layer known as the corrugating medium. The corrugating medium is shaped into arches and bonded between the linerboards, forming a sandwich structure. This design creates air pockets that enhance the board’s rigidity, provide cushioning, and improve stacking strength.
How Corrugated Board is Made
Corrugated board comes in various types:
- Single-wall – One fluted medium between two liner sheets.
- Double-wall – Two fluted mediums between three liner sheets.
- Triple-wall – Three fluted mediums between four liner sheets.
How Flute Type Affects Box Performance
The flutes in corrugated boards affect the board's thickness, cushioning, strength, and surface appearance. These are classified into different types: A, B, C, E, and F. "A" flutes are larger and generally provide more cushioning and vertical compression strength, while smaller flutes like "E" and "F" have a thinner, smoother surface ideal for retail packaging and detailed graphics.
Here are some common flute types and their typical applications:
| Flute Type | Approx. Thickness | Flutes per Foot | Best For |
|---|---|---|---|
| A Flute | ~4.8 mm (3/16") | ~33 | Fragile products, heavy items, and applications where cushioning and stacking strength are priorities |
| C Flute | ~4.0 mm (5/32") | ~39 | General shipping boxes, e-commerce packaging, and applications that need a balance of cushioning and strength |
| B Flute | ~3.0 mm (1/8") | ~47 | Die-cut boxes, retail packaging, canned goods, and applications where crush resistance and a flatter surface are important |
| E Flute | ~1.6 mm (1/16") | ~90 | Retail boxes, product packaging, displays, and packaging that needs better print quality and a thinner profile |
| F Flute | ~0.8 mm | ~125 | Small retail boxes, premium product packaging, and applications where a smooth print surface and compact design are important |
Note: Thickness and flute counts can still vary by manufacturer, paper grade, and board construction.
As a simple rule of thumb:
- A flute: More cushioning and stacking strength
- C flute: A good all-purpose option for shipping
- B flute: More compact with good crush resistance
- E flute: Thin and print-friendly for retail packaging
- F flute: Very thin and suited to small, presentation-focused packaging
Common Uses for Corrugated Board
Because of its strength and versatility, a corrugated board is used in various types of packaging. They are commonly used for:
- Shipping boxes
- Mailer boxes
- Product boxes
- Subscription boxes
- Protective packaging
- Retail displays
What is Paperboard?
Paperboard is a thick, paper-based material that is generally flat and compact, without a fluted middle layer. You can print, cut, score, fold, coat, and finish it in many ways, making it a popular option for retail and product packaging.
Paperboards come in several types. These are:
| Paperboard Type | Description | Common Uses |
|---|---|---|
| Folding Boxboard (FBB) | Lightweight, stiff, and designed for high-quality printing and folding | Cosmetics, food, pharmaceuticals, and consumer products |
| Solid Bleached Sulfate (SBS) | Bright white paperboard with a smooth surface that works well for detailed printing and finishing | Premium retail packaging, cosmetics, food, and electronics |
| Solid Unbleached Sulfate (SUS) | Strong, brown or natural-colored paperboard made from unbleached fibers | Beverage carriers, food packaging, and heavier retail products |
| Coated Recycled Board (CRB) | Made largely from recycled fibers and typically has a coated printing surface | Cereal boxes, dry food packaging, and general consumer packaging |
| Uncoated Recycled Board | Recycled paperboard without a coated surface, giving it a more natural appearance | Shipping inserts, dividers, backing cards, and basic packaging |
The differences between each type come down to strength, appearance, printability, and intended use. For example, SBS is often used for premium packaging, while recycled boards are suitable for recycled content.
Paperboard vs. Cardboard
Is paperboard the same as cardboard?
The quick answer: No.
Cardboard is a generic term used casually to describe thick, paper-based packaging. In the packaging industry, it's more appropriate to identify specific materials, such as corrugated board or paperboard.
Common Uses for Paperboard
Paperboard is commonly used for folding cartons and other lightweight packaging. Folding cartons are designed to fold flat before assembly, making them convenient to transport and store. They also provide a smooth surface for detailed graphics, coatings, embossing, and other finishing options.
Common paperboard applications include:
- Folding cartons
- Product boxes
- Food packaging
- Cosmetic packaging
- Retail packaging
- Promotional packaging
Corrugated vs. Paperboard: Key Differences
Corrugated board and paperboard differ primarily in their construction. Below is a side-by-side comparison to highlight what makes each material unique:
| Feature | Corrugated Board | Paperboard |
|---|---|---|
| Construction | Flat liners with a fluted middle layer | Thick, flat paper-based board |
| Strength | Designed for strength, cushioning, and stacking | Better suited to lightweight packaging |
| Protection | Provides greater protection for shipping and handling | Provides basic product protection |
| Appearance | Available in different surfaces and printing options | Smooth surface is well suited to detailed graphics |
| Common Formats | Shipping boxes, mailers, product boxes | Folding cartons and retail packaging |
| Storage | Boxes can be stored flat before use | Folding cartons can also be stored flat |
| Cost | Varies by construction, size, printing, quantity, and production | Varies by grade, thickness, printing, quantity, and production |
| Recyclability | Widely recovered through paper recycling systems, subject to local requirements | Often recyclable, depending on construction, coatings, contamination, and local programs |
| Best Suited For | Shipping, transport, and protective packaging | Retail, product presentation, and lightweight packaging |
Structure and Strength
Corrugated board is a more durable packaging option because its fluted layer creates rigid columns while also providing cushioning for frequent handling, stacking, and transportation. Its performance is also measured through the Edge Crush Test (ECT), a standardized method used by organizations such as the International Safe Transit Association (ISTA) and the American Society for Testing and Materials (ASTM), which applies increasing force to the board's edge until it buckles or collapses.
On the other hand, paperboard is made of a flat sheet that can be folded into different shapes. This makes it useful when you're prioritizing presentation, compact storage, and easy customization instead of heavy-duty protection during shipping.
Weight and Storage
Both materials are lightweight, but paperboard folding cartons are easier to store and ship than corrugated board. When deciding between the two, consider both the weight and the level of protection your product requires during storage and transit.
Printing and Appearance
While both materials can be customized to fit your branding needs, paperboard offers more flexibility for detailed graphics and finishing options. Paperboard is typically thinner, so it can be scored, folded, die-cut, embossed, coated, and foil-stamped for retail packages.
Meanwhile, printing on corrugated board depends on the construction and printing method. It can also support branded shipping boxes, mailers, displays, and other packaging formats.
Cost and Production
Packaging costs depend on more than just the material — they’re influenced by size, quantity, construction, finishing, and other factors. For example, a paperboard carton may be cheaper, but if it requires an additional shipping box or protective packaging, then it adds more to the real cost.
In terms of production, paperboard folding cartons might have a lower cost because they can be stored and shipped flat. As for corrugated board, it can be designed around the size and protection requirements of the product — making it more customized and possibly more expensive.
Recycling and Sustainability
According to industry reports, more than 96% of corrugated cardboard boxes are recycled. On average, each corrugated box contains about 50% recycled content, and its fibers are reused 7–10 times to manufacture new boxes and other paper products.
While both corrugated board and paperboard are fiber-based materials, it’s important to note that recyclability depends on more than just the material name. Factors such as the amount of material used, the inclusion of recycled fiber, transportation and usage methods, and post-consumer disposal all play a role.
Which Material Is Best for Shipping?
If your products need to travel through a delivery network, corrugated board is often the best choice because its fluted construction provides strong structural support and cushioning. Still, the ideal box will depend on your specific product and the conditions it will face during transit.
Which Material Is Best for Retail Packaging?
If your products are displayed on shelves or handed directly to customers, paperboard is your go-to option. It strikes a nice balance between visual appeal and practicality, making it perfect for retail displays.
Choosing Between Folding Cartons, Rigid Boxes, and Corrugated Mailers
Can't decide which type of packaging suits your product? Use our quick guide below:
| Packaging Type | Best Suited For | Main Advantage |
|---|---|---|
| Folding Carton | Retail products and lightweight packaging | Printable, foldable, and efficient to store |
| Rigid Box | Premium and gift packaging | Substantial structure and elevated presentation |
| Corrugated Mailer | E-commerce and direct-to-consumer orders | Combines shipping protection with branding |
| Corrugated Shipping Material | Products that need transportation protection | Strong, versatile, and available in different constructions |
Folding cartons provide a smooth printable surface and can be customized with structural features and finishes that help products stand out. They can also fold flat, which makes it convenient to store and transport them before assembly.
On the other hand, corrugated packaging isn’t just for shipping — it can work well for retail too, especially if your packaging needs to double as protection during delivery. This is a big plus for e-commerce brands shipping directly to customers’ doors.
Finally, if you want your product to really stand out, rigid boxes are a great pick. With their sturdy build and premium feel, they’re a favorite for gifts, luxury items, or anything that needs to make a strong first impression.
How to Choose the Right Packaging Material
Instead of choosing based on the material alone, think about how the packaging will be used.
- Start by looking at your product itself: its size, weight, shape, and fragility all matter. For instance, if you’ve got a lightweight item meant for a retail shelf, a simple paperboard carton should do the trick. But if your product is bulkier or will be shipped, corrugated board adds that extra layer of protection.
- Next, think about how the package will be used. Will it be shipped, stacked, or handled a lot? In those cases, durability and protection come first. But if you’re going for an eye-catching presentation, focus on materials that help your product stand out.
- Branding is also key. How do you want the product to look and feel in your customers’ hands? Maybe you prefer a smooth surface and crisp graphics, or you may want the packaging itself — like branded shipping boxes — to be part of the unboxing experience.
- Don’t forget your budget. Be sure to factor in everything: packaging size, order quantity, printing, finishing touches, storage, shipping, and any extra inserts or protective materials.
- Finally, consider sustainability. If eco-friendliness matters to you, take a close look at recycled content, recyclability, coatings, construction, and whether there are recycling programs available for your material.
Corrugated vs. Paperboard: Which Should You Choose?
Choosing the right packaging material depends on your product’s requirements and intended use.
Choose corrugated board when:
- Your product needs protection during shipping.
- The package needs to withstand stacking and handling.
- You need a shipping box or mailer.
- Your product is heavy, fragile, or sensitive to impact.
Choose paperboard when:
- Your product needs retail packaging.
- Detailed graphics and finishing are important.
- You want a lightweight folding carton.
- The package needs to fold flat for storage and transport.
Choose the Material That Fits the Job
Knowing the difference between corrugated and cardboard takes the guesswork out of picking the right packaging. Corrugated board provides strength and cushioning, perfect for shipping and keeping things safe. On the other hand, paperboard is lightweight, easy to print on, and works great for retail packaging or when you want your product to look polished and presentable.
At the end of the day, the best material is the one that matches your product and the vibe you want for your customers. Think about protection, looks, cost, and sustainability as a package deal. When you pick what works best for your needs, your packaging will keep your products safe and help show off your brand.
