Types of cardboard
The difference between cardboard and paper lies primarily in their load-bearing capacity. Cardboard is multi-layered and usually coated only on one side (most commonly matte), whereas paper is coated on both sides (matte or glossy) and consists of a single layer. Their intended use also differs: paper is used for commercial purposes such as brochures, folders, catalogues and magazines, while cardboard is mainly used for packaging.
At Jamnik, we manufacture packaging from solid and corrugated cardboard. Solid cardboard is significantly sturdier than corrugated cardboard. Due to its density and single-layer structure, it has a high load capacity and resistance to various stresses. Therefore, it is used for packaging, folders, covers, and other products that require greater strength.
Solid cardboard has a smooth and flat surface, allowing for easy printing, drawing or gluing. Its rigid structure provides high stability and stiffness. This means it retains its shape and does not easily deform under loads or under pressure. It is generally less sensitive to moisture than corrugated cardboard. Its density and smooth surface make it less prone to moisture absorption, helping to preserve its properties and strength.
Corrugated cardboard consists of at least two layers and can go up to five or even seven layers. The first outer layer is smooth, while the inner layer is corrugated, which is where its name comes from.
