In a significant collaboration from May 20th to 22nd, the team from Shiner Functional Films National and Local Joint Engineering Research Center joined forces with technical experts from Zhejiang Hisun Biopharmaceutical Co., Ltd., product development engineers from Natureworks, and technical staff from Guilin Electronic Science Institute to conduct pilot production of BOPLA films. The primary objective of this pilot was to produce high-quality tape base films and single-sided heat-sealable films.

Through precise equipment tuning and formulation optimization, the team successfully manufactured a 28-micrometer thick tape base film and a 25-micrometer thick single-sided heat-sealable film. The success of this pilot not only demonstrated the reliability and stability of Hisun's polylactic acid raw materials but also provided empirical support for the process conditions required to produce various biaxially stretched polylactic acid films.

The pilot production line at Guilin Electronic Science Institute provided a crucial experimental environment for this trial, showcasing the breakthroughs achievable in materials science through interdisciplinary teamwork. This collaboration has further strengthened the ties between industry and research institutions, laying a solid foundation for larger-scale industrial production in the future.
