The fluted paper is then adhered to flat linerboards to create a single, double, or triple wall corrugated sheet, depending on the desired product.

The adhesive used, typically a starch-based glue, is applied precisely to ensure a strong bond. Once the glue has set, the corrugated sheet is cut and scored to the required size and shape. The result is a robust, flexible, and lightweight material that is ready for use in a variety of packaging applications.

The Role of Flutes in Corrugated Pads & Sheets

Flutes are the wavy, arch-shaped paper that makes up the middle layer of corrugated sheets. They play a crucial role in the performance of these materials. The flutes provide rigidity and strength, resisting pressure and impact from various directions. They also create an insulating layer that protects products from sudden temperature changes.

Different flute profiles, identified by letters (A, B, C, E, and F), are used to achieve different performance characteristics. For instance, A-flute offers excellent cushioning and stacking strength, while B-flute provides high resistance to puncture and crushing. E and F flutes, being smaller and denser, are commonly used in retail packaging where a smooth and high-quality print finish is required.

The science behind corrugated pads and sheets is a testament to the ingenuity of packaging engineering. By understanding the manufacturing process and the role of flutes, you can better appreciate the remarkable properties of these humble packaging materials.
