China's First 9.1m BOPP Film Production Line Achieves Dual Breakthroughs in Zero Waste Film and High Production Capacity

The article is excerpted from "Insulation Materials".

        On December 29,2025, Guilin Grace Technology Co., Ltd. (a subsidiary of Guilin Electric Apparatus Research Institute Co., Ltd., abbreviated as "Guilin Electric Apparatus Research Institute") successfully launched China's first 9.1-meter-wide BOPP biaxially oriented film production line. This milestone not only expanded domestic equipment width from 8.7 meters to 9.1 meters but also achieved dual breakthroughs in energy efficiency and productivity through "zero waste film" and "high production capacity". It signifies China's successful resolution of core technical challenges in high-end film equipment, significantly advancing the development of independently controllable advanced film equipment in the country.

Automatic Four-Side Chamfering Machine

        This machine is designed for simultaneous chamfering of all four longitudinal edges on workpieces such as laminated wood, laminated paperboard, spacers, and wooden semi-finished products.

        The domestically developed 9.1-meter-wide BOPP production line represents a dual breakthrough in both technological advancement and environmental sustainability for film manufacturing. This innovation not only delivers core advantages of low consumption, high efficiency, and eco-friendliness, but also addresses persistent industry challenges during pilot production phases, including raw material waste and environmental clutter. The system achieves "zero waste film output" and leads domestic standards in material input efficiency, while demonstrating exceptional production line precision and operational stability. The resulting BOPP films exhibit superior mechanical and electrical properties, along with outstanding cold resistance, gas tightness, and dimensional stability. These characteristics enable versatile applications across premium packaging sectors such as food, electronics, and medical supplies, offering a "domestic alternative" for downstream industrial upgrades.

        As one of China's few institutions with turnkey production capabilities for bidirectional stretch film manufacturing lines, Guilin Electric Power Research Institute (GEPRI) has consistently driven innovation through technological advancement. Addressing critical industry challenges like high-speed chain-rail systems and stretch synchronization control, the institute formed dedicated teams to tackle these bottlenecks. Their breakthroughs in key component localization have not only elevated production line stability, reliability, and cost efficiency to domestic leadership levels, but also narrowed the technological gap with foreign counterparts.

        The successful operation of this 9.1-meter-wide BOPP production line not only epitomizes the decades of technological accumulation by Guilin Electric Power Research Institute, but also accelerates the transformation of China's packaging materials industry toward high-end and green development. This achievement injects strong momentum into the self-reliance of high-end film equipment and the high-quality development of the industrial chain in China.
