Types of Corrugated Material
Corrugated material is defined by its structure: layers of flat paper (linerboard) glued to a wavy, fluted sheet (the medium), forming a strong, rigid board. The main variables are:
1. Single Wall Corrugated
- Composition: Two linerboards with a single fluted medium in between.
- Use Cases: Standard shipping boxes, mailers, retail cartons.
- Benefits: Lightweight, cost-effective, easy to print.
2. Double Wall Corrugated
- Composition: Three linerboards and two mediums (one inside, one outside).
- Use Cases: Heavy goods, products that need stacking or extra protection.
- Benefits: Improved crush resistance, enhanced durability.
3. Triple Wall Corrugated
- Composition: Four linerboards with three fluted cores.
- Use Cases: Industrial shipping, hazardous materials, export, bulk bins.
- Benefits: Maximum strength, equivalent to small wooden crates.
4. Single Face Corrugated
- Composition: One linerboard attached to an exposed fluted medium.
- Use Cases: Wrapping, cushioning, interleaving layers inside packages.
- Benefits: Flexible, excellent for protective inner layers, low cost.
Board Flute Types
Flutes refer to the shape and size of the arch created by the corrugated medium. Each size offers unique properties:
- A Flute: Largest (about 5 mm thick), best cushioning and stacking strength, ideal for fragile items.
- B Flute: Thin and stiff, excellent puncture and crush resistance, often used for canned goods.
- C Flute: Most common, all-purpose cushioning and strength.
- E Flute: Thin (about 1.5 mm), ideal for retail displays and cartons with excellent print surfaces.
- F Flute: Very thin, often used for small retail boxes, good print quality.
Different wall structures can also combine flutes (e.g., BC or BE double wall) to optimize strength or performance.
Comfort, Handling, and Usability
When considering corrugated material, comfort becomes important from handling and end-use perspectives, especially if you’re managing inventory, packaging products, or unpacking goods.
Comfort and Handling
- Lightweight: Even heavy-duty triple wall is easier to handle than wood or metal.
- Smooth Edges: Quality corrugated is die-cut for safety and ease of folding or taping.
- Easy Assembly: Designed for quick folding, slotting, and closure—with no tools needed.
User-Friendly Features
- Custom Sizing: Corrugated sheets and boxes can be ordered to fit any product, reducing wasted space and risk of damage.
- Opening and Resealing: Many boxes are designed for repeated opening/closing—vital for e-commerce, returns, and retail displays.
Aesthetics and Printability
- Kraft/Brown: Classic, eco-friendly, and hides dirt during transit.
- White/Mottled White: Better for printing logos or bright graphics.
- Premium Clay-Coated: Vibrant, high-saturation colors for strong shelf presence.
Caring for Corrugated Material
Corrugated is durable, but good care extends its lifespan and performance.
Basic Care Tips
- Keep Dry: Corrugated is made from paper and loses strength if it gets wet. Store in dry locations, and choose water-resistant coatings for humid environments.
- Avoid Overloading: Even strong corrugated has safe weight limits. Stack within manufacturer’s guidelines to prevent crushing.
- Flat Storage: Stack unused sheets flat, not on edges, to avoid bending or warping.
- Reusing: Gently flatten after use for storage or recycling. Avoid creasing or tearing the structure.
Cleaning
For re-use or storage, brush off dust and wipe with a dry cloth. Never wipe with wet rags; for stubborn stains, use a barely damp sponge and dry immediately.
Choosing Corrugated Material for Different Needs
Selecting the best corrugated option depends on what you’re packaging, shipping, or displaying.
For Shipping
- Single Wall: Good for most everyday parcels, light-to-medium loads.
- Double Wall: Use if shipping heavy, dense, or fragile items, especially for stacking.
- Triple Wall: Reserve for extra-heavy, hazardous, or export goods.
For Retail Display and Product Packaging
- E or F Flute: Crisp, smooth surfaces allow high-quality printing and attractive visuals.
- White or Coated Liners: Prefer for branding and aesthetics.
For Storage or Moving
- Single or Double Wall: Balance needed between lightweight handling and box strength.
- Easy Fold Styles: Look for regular slotted containers (RSC) for quick assembly and closure.
For Inner Packaging and Cushioning
- Single Face or Pads: Flexible and ideal for wrapping or separating delicate items.
For Custom Applications
- Die Cut Boxes: Custom-molded to fit specific products—great for electronics, medical, or promotional kits.
- Special Liners: Opt for premium, coated, or moisture-resistant liners based on your environment.
Practical Tips & Best Practices
- Measure Carefully: Choose box size based on internal dimensions, making sure there’s enough space for products and any internal padding, but not so much that contents shift.
- Pick the Right Flute: For retail visuals, choose smaller flutes (E/F); for cushioning, pick larger (A/C).
- Consider the Closure: Tape provides moisture and tamper protection, while staples offer security for heavy loads.
- Maximize Pallet Use: Choose box sizes that optimize pallet layouts, reducing shipping costs.
- Custom Printing: Promotional and retail packaging benefits from high-quality graphics—select higher-grade white liners or coated stock for these applications.
- Think about Recycling: Corrugated is among the most recycled packaging materials—flatten boxes for curbside pickup or business recycling.

FAQ
-
What exactly is corrugated material?
Corrugated material is made from layers of paperboard—two flat linerboards bonded to a fluted (wavy) medium. This structure gives it strength, rigidity, and cushioning, making it ideal for boxes and packaging. -
How is corrugated material different from cardboard?
Cardboard is a general term for thick paper or paperboard. Corrugated material specifically refers to the layered structure with a central fluted medium, making it stronger and more protective than plain cardboard. -
What are the main types of corrugated material?
The primary types are single wall, double wall, triple wall, and single face. Each varies in the number of liners and mediums (fluted layers), which affects strength and durability. -
What does ‘flute’ mean in corrugated material?
A flute is the wave-shaped layer between the linerboards. Different flute sizes change the cushioning, stacking strength, and print quality. Common flute sizes include A, B, C, E, and F. -
How do I choose the right corrugated material for my product?
Consider your item’s weight, fragility, shipping conditions, and branding needs. For heavier or fragile items, pick double or triple wall with larger flutes. For lightweight or display products, single wall with smaller flutes (E or F) works well. -
Is corrugated material recyclable?
Yes! Corrugated material is highly recyclable and often made from recycled content. Just flatten boxes after use and add them to your recycling bin. -
Can corrugated boxes be reused?
Absolutely. If boxes remain in good condition after use, they can be easily broken down, stored flat, and reused for shipping, storage, or moving. -
What printing options are available for corrugated packaging?
Corrugated can be printed using flexographic, lithographic, or digital methods. Options range from simple logos or text to vibrant full-color graphics—especially on white or coated liners. -
What are the common box styles made from corrugated material?
Popular styles include Regular Slotted Containers (RSC), Full Overlap (FOL), Telescoping boxes, Five-Panel Folders (FPF), and custom die-cut forms for unique products. -
Are there moisture-resistant or food-safe corrugated materials?
Yes. Custom coatings and liners can be applied for water resistance, grease resistance, or direct food contact, making corrugated suitable for produce, frozen foods, and more.
