Corrugated plastic
From Wikipedia, the free encyclopedia
Corrugated plastic or corriboard, also known under the tradenames of Coroplast, Correx, Corriflute, Corflute, Polyflute or Twinplast, refers to a wide range of extruded twinwall 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 craft knife. Manufacturers typically offer a wide variety of colors and thicknesses (quite commonly 4 mm).
Corrugated plastic is also referred to as Twinwall plastic.
Chemically, the sheet is inert, with a neutral pH factor. At regular temperatures most oils, solvents and water have no effect, allowing it to perform under adverse weather conditions or as a product component exposed to harsh chemicals. Standard sheets can be modified with additives, which are melt-blended into the sheet to meet specific needs of the end user. Special products that require additives include: ultra violet protection, anti-stat, flame retardant, custom colors, corrosive inhibitors, static-dissipative, among others.
This material is commonly used to create political signs, campaign signs, and election signs and for constructing plastic containers and reusable packaging. It is widely used in the packaging of automotive and electronic parts as well as agricultural produce.
