The study investigates the stress-induced crystallization of biaxially oriented polypropylene (BOPP) during hot stretching at high temperatures. It was found that the stretching ratio significantly affects the crystalline structure, with an average increase in crystallinity of about 20% observed after stretching. The research confirms that β-crystal modification does not occur during the machine direction hot-stretching process, as indicated by differential scanning calorimetry and wide-angle X-ray diffract
