Corrugated cardboard is composed of a flat, thick liner layers of paper adhered to alternating fluted layers.


Corrugated cardboard varies in paper thickness, the width of the flutes and the amount of liner-flute layers, providing many solutions for various packaging demands.



Corrugated cardboard can also vary in the maximum weight that it supports, in the adhesives used to glue layers together, in the amount of additional layers and in what protective treatment is applied to the corrugated cardboard.



Because of its paper surface, corrugated cardboard can easily receive direct image and letter printing from silk screening, flexography and lithography.



The design of corrugated cardboard also makes it able to absorb impact and resist damage from accidental drops. It is designed for stacking and storing products to protect them from damage.



Corrugated cardboard is a renewable environmental product. It is made from eco-friendly fibers that come from recycled paper products, wood manufacturing by-products and straw.
