Corrugated plastic

From Plastics Wiki, free encyclopedia

Corrugated plastic, also known under the tradenames of Coroplast, Corriflute 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 cardboard. It is a light weight tough material which can easily be cut with a craft knife.

Chemically, the sheet is inert, with a nil 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 commercial signs and for constructing plastic containers and packaging. It is widely used in the packaging of automotive and electronic parts as well as agricultural produce.

It has recently found a use among guinea pig and other small pet enthusiasts as a component of a type of DIY cages. Additionally, it is used by members of the r/c aircraft community to build nearly indestructible SPAD (simple plastic airpane designs) model aircraft.

Corrugated sheet is recyclable and therefore considered environmentally friendly.
