Fluting is a technique commonly used to increase a material’s performance characteristics by incorporating a wavy, tubular, or ridged structure, usually in the middle layer. It offers a range of advantages across various applications.
Enhanced Strength-to-Weight Ratio
The fluted structure significantly increases the material’s strength while maintaining a low weight. With its hollow spaces, a fluted design reduces the overall weight of the material without compromising strength. This provides the ability to support substantial loads without adding excessive bulk, making it ideal for packaging, construction, and transport. Lightweight materials are easier to transport, install, and handle, reducing transportation costs and labour.
Additionally, flute ridges provide additional rigidity and allow the material to resist bending, folding, or crushing under pressure. This is ideal for applications where the material needs to be stiff and maintain its shape, such as in signage or construction panels. The lightweight yet rigid quality of some fluted materials makes them easy to stack without bending or compressing under weight, making them ideal for storage, pick bins, transport, and retail display purposes.
Impact and Shock Absorption
Fluting has a cushioning effect as its structure disperses impact forces across the ridges. This is a valuable attribute for protecting fragile items during shipping and handling, reducing the risk of damage.
Material Efficiency and Sustainability
The fluting process uses less raw material to achieve strength, making it a resource-efficient option. This reduces production costs and waste, which is important in industries focused on cost-efficiency and sustainability. Many fluted materials, such as corrugated cardboard or polypropylene, are recyclable, providing sustainable solutions for industries focusing on reducing environmental impact, particularly in packaging and manufacturing.
Reduced Material Fatigue
The fluted structure offers excellent flexibility and resilience, allowing for slight bending without breaking. This reduces the likelihood of material fatigue over repeated use, especially in applications requiring repeated bending or handling. By prolonging the lifespan of the material, fluting reduces cost, waste, and carbon emissions.
Thermal Insulation
Air pockets within the fluted structure can trap air, providing a degree of insulation that helps regulate temperature. This is useful in packaging sensitive items or creating temporary shelters.
Sound Insulation
The structure can also dampen sound and vibration by dispersing sound waves within the flutes. This is useful for creating sound-insulating barriers or packaging materials that protect noise-sensitive items.
Environmental Benefits
Many fluted materials, such as corrugated cardboard or polypropylene, are recyclable, offering sustainable solutions for industries focused on reducing environmental impact, particularly in packaging and manufacturing.
Customisability
Fluting can be designed in different sizes and shapes to achieve varying levels of strength and flexibility. This enables customisation for specific needs, whether for heavy-duty applications or lightweight protection.
What is the Best Material to Use in Fluted Applications?
Fluting can be applied to a range of materials, including cardboard, metal, and wood. Cardboard is popular for fluting, but its vulnerability to moisture and harsh environments compromises the qualities provided by fluting – it quickly loses its rigidity and resilience. When stacked, cardboard solutions don’t always have the same strength and weight-bearing capability in the long-term; over time, it will start to sag when containing heavier items, especially in damp environments.
Polypropylene is ideal for the production of fluted sheets. Twinplast clients utilise our fluted polypropylene products for a host of purposes. We supply corrugated polypropylene to meet bespoke designs and specifications, making maximum use of the versatility of fluted construction. We can design the thickness and structure of the flutes to determine the strength and flexibility required for the product. Our fluted sheets are especially useful for packaging and storage, including warehouse pick bins, but they can be applied to a multitude of uses. Our bespoke design and manufacturing offer countless possibilities.
