2. Lightweight and Efficient
- Corrugated packaging considerably reduces shipping weight, which saves on freight costs.
- Easy to handle and assemble, making it a favorite for both warehouses and consumers.
3. Environmentally Friendly
- Made primarily from renewable resources and recycled content (typically 70%–100% recycled fibers).
- Fully recyclable; with a recovery rate over 90%, it’s one of the most recycled materials on the planet.
- Many box styles are reusable—for storage, moving, or crafts—before finally being recycled.
4. Cost-Effective
- Lower raw material and production costs versus plastic or wood alternatives.
- Custom sizing minimizes material waste and optimizes shipping space, further saving money.
5. Highly Customizable
- Manufacturers offer custom sizes, flute types, graphics, and coatings to match nearly any product’s needs.
- Cutting-edge printing technologies can create high-quality branding that reinforces your message at the point of sale.
How to Choose the Right Corrugated Fiberboard
Selecting the best corrugated fiberboard depends on understanding your product’s protection needs, intended use, and cost considerations. Here’s a step-by-step guide:
1. Assess the Purpose
- Shipping: Choose strength and protection (consider double or triple wall for heavy/bulky items).
- Display / Retail: Prioritize a smoother surface and printability (E or F flute for high-res graphics).
- Storage: A balance between stacking strength and weight.
- Food Packaging: Opt for food-grade board and moisture-resistant coatings if necessary.
2. Select the Right Structure
- Single Face: Ideal as cushioning or wrapping around individual products inside a box.
- Single Wall: Most common for standard shipping; offers good balance of strength and affordability.
- Double Wall: Needed for heavier, bulkier, or fragile products requiring extra protection.
- Triple Wall: Choose for industrial shipping, export containers, or exceptionally heavy items.
3. Pick the Suitable Flute Type
Flute type impacts cushioning, stacking strength, and surface for printing:
- A Flute (≈4.7 mm): Excellent cushioning; bulkier boxes.
- B Flute (≈2.5 mm): Good puncture resistance, compact size.
- C Flute (≈3.6 mm): General-purpose; most common for shipping cartons.
- E Flute (≈1.5 mm): Thinner, better for printing, used in retail and food service packaging.
- F Flute (≈0.8 mm): Very thin; ideal for small boxes with detailed graphics.
Double wall can combine flute types (like BC or EB) for tailored performance.
4. Consider Performance Testing
- Edge Crush Test (ECT): Measures stacking strength. The higher the value (e.g., 32 ECT), the more weight the box can support stacked.
- Mullen Burst Test: Measures resistance against bursting. Important for protecting heavy or point-loaded items.
5. Determine Additional Features
- Coatings: Wax for moisture resistance, flame-retardant for extra protection, or anti-static for electronics.
- Custom Inserts/Partitions: For separating multiple items or adding support.
- Printing Choices: Important for branded retail packaging. Options include flexographic, lithographic, and digital printing.
Tips and Best Practices for Using Corrugated Fiberboard
For Buyers and End Users
- Order the Right Size. Custom dimensions avoid excess material, reduce shipping costs, and better protect your goods.
- Check Box Construction. Match wall type and flute size to your product’s weight and fragility.
- Know Your Testing Standards. Choose boxes rated by ECT for stacking or Mullen for burst resistance, according to your requirements.
- Choose Proper Coatings. If contents are moisture-sensitive or perishable, request wax or polymer coatings.
- Ask About Recycled Content. For sustainable sourcing, seek high post-consumer recycled content.
- Reuse Before Recycling. Many boxes can be collapsed and reused several times for storage, moving, or donation.
- Store Boxes in Dry, Flat Spaces. Prevent warping or weakening from excessive humidity or stacking.
For Businesses
- Work With a Knowledgeable Supplier. They can advise on optimum board grade, flute, and design for your specific products.
- Invest in Quality Printing. High-quality graphics improve perceived brand value and shelf impact.
- Leverage Modular Designs. Use standardized box sizes to streamline inventory, shipping, and warehousing.
