Oriented polypropylene film technologies
1. Tomsk Polytechnic University
Today consumers expect product to have good protection. Flexible packaging materials play a great role in many industries. BOPP film is one of the most popular materials that is in demand in almost any field where flexible packaging is required. Most oriented plastic films have a biaxial orientation, the characteristics of which perfectly correspond to the requirements of modern flexible packaging. General improved barrier properties are achieved due to the orientation of the chains of molecules. Tension in the longitudinal direction is usually performed using the machine direction orientation (MDO) through the rollers with increasing speed. For all transversely oriented films, the stretching process occurs using a transverse directional orientation (TDO), where the film is fixed at both ends and, after passing through the oven at different temperatures and it is stretched in the transverse direction.
