Corrugated plastic is usually made from polypropylene which is capable of being recycled. Fluted (corrugated) Polypropylene (PP) sheet, a polyolefin product, is a lightweight, material known for its versatility across many industries and applications. Fluted PP is used in Graphic Arts, Packaging, Agriculture, Automotive and Industrial markets. Common applications include signage, trade show and retail display, binding/stationary, crates, as separators or liners in packaging, vehicle trunk liners, and more. Sturdy, reusable, recyclable, returnable, waterproof fluted polypropylene shipping containers are superior to corrugated paper. Polypropylene offers good resistance to chemical or acid attacks and has low moisture absorption and superior electrical insulation.
