Corrugated plastic is an extruded material similar in appearance to corrugated paper. Both upper and lower surfaces are supported by fluted ribs. Several thicknesses are available, 2mm to 10mm. The material is available in polypropylene. Amerisource Custom Packaging stocks only polypropylene because it is preferred for most applications. Thicknesses available are from 2mm to 10mm. The stock material is treated for UV resistance; flame retardant, anti-static and conductive sheet are available. The sheet is corona treated, which provides an excellent surface for screen printing and other decoration methods. Fluted plastic sheet offers several advantages over corrugated paper, solid plastic sheet, and other sheet materials. It is light weight, yet tough and abrasion resistant. Polypropylene has excellent chemical resistance and is unaffected by water.
