Hollow board (also known as corrugated plastic sheet, twin-wall sheet, or fluted sheet) is a lightweight (due to its hollow structure), non-toxic, pollution-free, waterproof, shock-resistant, aging-resistant, and corrosion-resistant material available in a wide range of colors.
Compared to cardboard-based products, hollow board offers advantages such as moisture and corrosion resistance.
Compared to injection-molded products, hollow board offers benefits including shock resistance, design flexibility, and the elimination of the need for expensive injection molds. Furthermore, by controlling the raw materials-such as through the flexible addition of anti-static or conductive masterbatches-manufacturers can produce hollow boards with specific conductive or anti-static properties; the surface resistivity of anti-static boards can be controlled within the $10^6$ to $10^{11}$ ohm range, while that of conductive boards can be controlled within the $10^3$ to $10^5$ ohm range.
