Recently, Shaanxi Yanchang China Coal Yulin Energy and Chemical Co., Ltd. (hereinafter referred to as: Yanchang China Coal) upgraded its thin-wall injection molding polypropylene K1870-E. With the help of Milliken's innovative additive solutions, the upgraded new generation product has excellent stiffness-toughness balance and good dimensional stability. It also has good processing performance and is not prone to warping and deformation. It is mainly used in the production of various specifications. Disposable food packaging boxes and containers.
K1870-E uses Milliken’s Hyperform® HPN™ high-performance additives, the upgraded additive formula optimizes the crystallization temperature and semi-crystallization cycle of the product in the injection molding process, improves the production efficiency of injection molded packaging box products, and thus significantly saves energy consumption. In addition, food packaging products produced using K1870-E have high toughness and transparency, which not only ensures that food packaging boxes are not easy to turn yellow after high-temperature processing, but also greatly improves the stiffness and heating stability of the box body, and through optimization The injection molding process reduces the unit weight of food packaging products, achieving the effect of reducing plastic and cost.
In terms of production technology, the upgraded product of K1870-E adopts advanced The spherizone multi-zone circulation reactor is used for production, which not only achieves a substantial increase in production capacity, but also significantly improves product performance. In 2022, Yanchang China Coal's thin-wall injection molding polypropylene special material production capacity will reach 300,000 tons, and it will have a large market share in the country. In addition, through catalyst optimization and process adjustment, Yanchang China Coal has the ability to continuously and stably produce phthalate-free thin-wall injection molded polypropylene to meet higher requirements for food contact packaging materials.
"With its stable quality and excellent performance, extended thin-wall injection molded polypropylene has always been favored by customers and has become one of the company's star products. We believe that with the recovery of market consumption, the food packaging industry will be more interested in thin-wall injection molded polypropylene. The demand for propylene will also maintain steady growth." The relevant person in charge of Shaanxi Yanchang China Coal Yulin Energy and Chemical Co., Ltd. said, "In the future, we will further expand the research and development of thin-wall injection molding polypropylene series grades, through the improvement of polymerization process and additive formula. Adjust, optimize, develop and upgrade products to help customers reduce costs and increase efficiency."
Under the guidance of the goal of building a "domestic first-class, world-renowned" modern energy and chemical enterprise, Yanchang China Coal has actively built a product research and development center and a polyolefin research and development team, and has developed and reserved nearly 100 new polypropylene grades.
At the same time, the company also owns Innovene, Sinopec ST-2 Environmental Pipe and Basell Spherizone's three production units cover the main domestic polypropylene production processes, bringing the polypropylene production capacity to 1 million tons. Since 2019, Yanchang Zhongmei Yuneng Chemical has been rated as "The Most Influential Enterprise in China's Polyolefin Industry" for four consecutive years.
