Biaxially oriented polypropylene (BOPP) and Biaxially oriented polyester (BOPET) are commonly produced in tender-frame lines. In these lines material is melted through a flat extrusion die (T-die) and solidified onto a cooled roller. Material is then stretched in machine direction in an MDO. Thereafter material is stretched in transversal direction in a TDO. These processes deliver a molecule orientation in both axes, this enhances many of their properties, particularly the mechanical, impact, barrier and optical properties.
