Corrugated cardboard is now the most widely used packaging material, thanks for its features of sturdiness,
versatility and lightness, in addition to its total recyclability and biodegradability.

Innova Group produces directly different types of corrugated sheets, with special characteristics. In its simplest form, corrugated cardboard consists of two surfaces of paper, called cover (avana-tobacco or white color), which contain internal paper undulation (wave) that sets the characteristics of stability and strength of the sheet.

The different types of corrugated cardboard are grouped together according to the thickness of the wave.
