Bubble Guard Sheet

Corrugated plastic or corriboard – also known under the trade names of Biplex, Cartonplast, Polyflute, Coroplast, FlutePlast, IntePro, Proplex, Correx, Twinplast, Corriflute and Corflute – refers to a wide range of extruded twin-wall plastic-sheet products produced from high-impact polypropylene resin with a similar make-up to corrugated fiberboard. It is a light-weight tough material which can easily be cut with a utility knife. Manufacturers typically offer a wide variety of colors, thicknesses (quite commonly 3, 4, 5 mm), and weight (measured in grams per square meter, or GSM).
