Corrugated Cardboard Packaging: A Revolution in the Packaging Industry and Its Impact on Modern Logistics

Corrugated cardboard is one of the most important packaging materials in the modern world, revolutionizing the way we produce, transport, and store goods. Since its invention in the 19th century, corrugated packaging has become an indispensable element of the global supply chain, influencing nearly every sector of the economy. In this article, we take a comprehensive look at this fascinating material—its properties, applications, environmental impact, and the future of the packaging industry.

History and Evolution of Corrugated Cardboard

Technological Origins

The history of corrugated cardboard dates back to 1856, when British inventors Edward Healey and Edward Ellis patented the first process for producing paper with a corrugated structure. Initially, this material was used as a hat liner to provide better ventilation and comfort. A breakthrough came when it was applied in the packaging industry.

In 1871, Albert Jones of New York patented the use of corrugated cardboard as protective packaging for glass and other fragile items. This marked the beginning of the modern era of cardboard packaging. Further innovations, such as Robert Gair’s introduction of a multi-layered structure in 1890, gradually transformed simple corrugated paper into a sophisticated engineering material.

Technological Development in the 20th Century

The 20th century brought dynamic advances in corrugated cardboard production technology. The introduction of mass production machinery in the 1920s significantly reduced costs and increased availability. Advances in packaging chemistry led to the development of various adhesives and coatings that improved mechanical and barrier properties.

The post-WWII period was particularly significant, as the rapid expansion of international trade and the rise of supermarkets created enormous demand for efficient packaging solutions. Corrugated cardboard met these needs perfectly, offering an optimal balance of cost and functionality.

Structure and Technical Properties

Structure of Corrugated Cardboard

Corrugated cardboard features a unique layered structure that gives it exceptional mechanical properties. The basic structure consists of:

Outer layers (liners) – Flat sheets of paper or board forming the external surfaces. They can be made from recycled paper or high-quality virgin kraftliner.
Corrugated layer (medium) – The core, made of paper shaped into a regular fluted pattern. This layer provides most of the material’s mechanical strength, including compression resistance and shock absorption.
Adhesives – Starch-based glues bond the layers together, ensuring structural integrity.

Construction Types

The packaging industry has developed several standard types of corrugated board:

Single Face – One fluted layer bonded to one flat layer. Mainly used as cushioning or inner packaging.
Single Wall – The most common type, with one fluted layer between two flat liners. Typically 3–4 mm thick.
Double Wall – Two fluted layers separated by three flat liners for greater strength. Thickness: 6–7 mm.
Triple Wall – The strongest type with three fluted and four flat layers. At 15 mm thick, it’s an alternative to wooden packaging.

Technical Parameters

Mechanical properties are defined by standardized metrics such as:

Edge Crush Test (ECT) – Measures vertical load-bearing capacity, critical for stacking stability.
Burst Strength – Indicates resistance to sudden point loads during handling.
Bending resistance – Important for folding and usability.
Barrier properties – Includes permeability to water vapor, gases, and contaminants.

Production Process

Raw Material Preparation

The process begins with preparing suitable paper grades. Modern facilities use both virgin fibers (mainly from softwood trees) and recycled materials. Recovered paper accounts for about 90% of raw materials, making corrugated cardboard one of the most eco-friendly packaging materials.

Preparation includes shredding, decontamination, de-inking, and refining the pulp for strength parameters.

Forming the Corrugated Structure

A key stage is forming the fluted layer using a corrugator machine. The medium paper is steamed for plasticity and passed between a fluting roll and a pressure roll to create the wave pattern.

Simultaneously, modified starch adhesive is applied to the flute peaks for optimal bonding and drying time.

Laminating and Drying

The fluted layer is laminated with the flat liners under heat and pressure to ensure adhesion. Modern machines run at speeds up to 300 meters per minute and widths up to 2.8 meters.

Finishing and Conversion

After cooling and conditioning, the board is rolled or cut into sheets per customer specifications.
