How flute types shape effective and sustainable displays
Corrugated board is a key material in Point of Sale (POS) communication. Its internal wavy layer—the flute—provides structure, strength, and versatility. The choice of flute type determines how a display performs in terms of durability, load capacity, and visual quality.
Why Corrugated Flute?
Corrugated flute is recyclable, lightweight, and cost-efficient. It offers reliable surfaces for printing, can be flat-packed for transport, and provides the durability needed for retail environments.
Main Flute Types in POS
E-Flute – Fine and Printable
Thin and smooth, perfect for detailed graphics. Used in countertop displays, smaller packaging, and decorative parts.
B-Flute – Versatile Standard
Balanced strength and material efficiency. Common in mid-size floorstands, stackable units, and lighter product displays.
EB-Flute – Reinforced Strength
A double wall combining E and B layers. Provides stability and load-bearing capacity for large floorstands, pallet displays, and durable multi-shelf units.
Special Flutes
Customized solutions developed to meet specific Edge Crush Test (ECT) performance, depending on load and campaign duration.
Stronger Variants and E–E Flute
For especially demanding retail environments, stronger corrugated structures are required. These include:
E–E Flute (Double E-Flute)
- Two E layers combined for extra rigidity while keeping the profile thin.
- Advantages: compact but strong, ideal for displays that require fine printing and additional durability without bulk.
- Applications: premium product displays, long-term countertop units, and packaging where appearance and strength must work together.
Heavy-Duty Double or Triple Wall Boards
- Designed for products with very high weight or for long-lasting installations.
- Applications: beverage or household product displays, POS structures in DIY or warehouse-style retail.
These stronger variants ensure that displays can safely carry heavy loads, remain stable over extended campaigns, and still offer the surface quality needed for branding.
Advantages in POS
- Supports vibrant graphics or eco-natural looks
- Provides reliable load capacity across product categories
- Easy transport and quick in-store assembly
- Fully recyclable and eco-compliant
- Adaptable from short-term promotions to long-term campaigns
Conclusion
Flute type is a strategic factor in POS design. From fine E-flute for premium graphics to heavy-duty EB or E–E for demanding campaigns, corrugated board combines sustainability with performance. By selecting the right material, brands achieve both strong in-store visibility and reliable durability.
