Definice<\/strong><\/strong><\/h2>\n\n\n\n

Cardboard is a general term for heavy paper-based products. It includes thin cardstock used for items like business cards and postcards, as well as thicker single-layer cardboard suitable for packaging materials. Even corrugated cardboard is a type of cardboard. However, in the packaging industry, the term “cardboard” is commonly used to refer to the thicker single-layer cardboard. In this article, we focus on this type of cardboard.<\/p>\n\n\n\n

Vlnit\u00e1 lepenka z\u00edskala sv\u016fj n\u00e1zev podle sv\u00e9 struktury.

Na str\u00e1nk\u00e1ch vlnit\u00e1 lepenka<\/mark><\/a> we commonly encounter consists of three layers \u2013 two layers of paper on top and bottom, with an intermediate layer of corrugated medium. In this structure, the corrugated medium, bent between the two layers of paper, forms numerous voids in the vertical direction between the layers of cardboard. This enables the cardboard to evenly distribute forces, thereby enhancing overall strength and making it less prone to damage. Additionally, the wave-like structure of corrugated cardboard effectively absorbs and slows down impacts, providing better protection for items inside the packaging. In terms of materials, corrugated cardboard doesn’t demand as high-quality pulp as cardboard. The pulp used for corrugated cardboard is often made from more affordable materials like recycled paper.<\/p>\n\n\n\n
