Fundamental knowledge about corrugated board construction and properties.

Corrugated board is the structural foundation of modern shipping and retail
packaging, composed of three essential layers that combine rigidity with
lightweight properties. The medium, also called the fluting, is the wavy
central layer that provides cushioning and stacking strength. The linerboards
are the flat outer layers that sandwich the medium, offering printable surfaces
and protection.

**Single Face vs. Single Wall vs. Double Wall:** Single face board has one
liner adhered to the corrugated medium, typically used for inner protective
wrapping. Single wall, the most common form, has two liners with one medium
between them — standard for shipping boxes. Double wall combines three liners
with two mediums, creating exceptional stacking strength for heavy or high-value
products.

**Manufacturing Process:** Corrugated board begins as rolls of Kraft paper.
The medium passes through heated corrugating rolls that shape the characteristic
flutes. Starch adhesive is applied to the flute tips, and the medium is pressed
against the linerboard in a single facer. For single wall and double wall
constructions, additional adhesive stations bond subsequent layers.

**Key Performance Metrics:** Burst strength measures resistance to puncture
and is critical for handling durability. Edge Crush Test (ECT) evaluates
stacking performance and determines how much weight a box can bear when stored
in a warehouse. These metrics guide specification decisions based on product
weight, storage conditions, and supply chain handling intensity.
