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.
