Corrugated Plastic started to be used as alternative for corrugated paper boxes in Europe in the late 1970’s. The United States began producing corrugated plastic in the mid 80’s. It also known under the tradenames of Corriboard, Polyflute, Coroplast, FlutePlast, InterPro, Proplex, Correx, Twinplast, Corriflute or Corflute - refers to a wide range of extruded twin-wall plastic-sheet products produced from high-impact polypropylene resin(PP). PP extruded corrugated plastic profile sheet is produced in I-Beam(also known as H-Beam) structure. This material is widely used to commercial, political signs and for constructing plastic containers, reusable packaging, pet cages and so on. It is made by an extrusion process through a die and when resin is pressed through the die it creates a sheet that has flat surfaces to both sides and an I-beam structure between the two flat surfaces.
