These days, corrugated plastic is referred to by several registered tradenames, one of which is Corflute. It is a twin-wall plastic sheet product made from polypropylene. The Corflute designation is a registered trademark of Corex Plastics, a manufacturer and supplier of multi-wall and solid sheet products based in Dandenong, a suburb of Melbourne, Australia.
Corflute sheets have several functions. Perhaps the most ubiquitous applications are temporary signage, products exhibits, and point-of-sale displays. However, they are also found at building sites, where they protect floors; as composite boxes in automotive components; as pharmaceutical and glass packaging; and as containers for produce to absorb moisture and provide wet strength. Moreover, electronics manufactures use Corflute for anti-static purposes — particularly for packaging sensitive components. Other common uses include home insulation applications, tree and vine guards, root barriers, water separators, solar panel protective sleeves, and temporary security windows.
Manufactured as lightweight material, Corflute has a make-up similar to corrugated fiberboard. It can be easily cut with a utility knife. Any equipment used to cut it, however, has to be very sharp with low hold-down pressure for precision and smooth edge finish. An utility knife is best suited for smaller job runs or craftwork, while conventional paper guillotining equipment is required for larger, more sophisticated projects. Corflute manufacturers usually offer a wide variety of thicknesses, the most common of which are 3, 4, and 5 millimeters. Common Corflute colors include blue, grey, black, yellow, red, green, and white.
The lightness of Corflute belies its strength and durability. Plus, they are impact- and water resistant, very flexible, non-toxic and resistant to chemicals, and are 100 percent recyclable. They are ideal for short-term outdoor applications, especially considering that they have a resistance to ultraviolet rays or other potentially harmful elements. Corflute is available in flame retardant version.
