2011年公司经过日本昭和电工株式会社的严格审查，成为日本昭和电工集团(SHOWA DENKO K.K)在华液态锂电和聚合物锂电材料在中国大陆区域的正式代理商，在中国国内销售高科技聚合物锂电池铝塑包装膜。日本昭和铝塑膜是全球最早运用于聚合物锂离子电池的铝塑复合膜，产品早在90年代末由昭和电工和SONY公司共同协作研发并批量生产，技术和质量成熟稳定，目前市场份额占了全球的75%-80%，现主要提供C4，C8两种型号铝塑膜，C4厚度为（113μ），C8厚度为（152μ），动深延展好、热封强度高，不易导致弯角部分的隐性龟裂,保障电池不易胀气。
晋佳股份有限公司本着“发展、和谐、互惠、诚信”的理念，愿与广大客户精诚合作，为锂离子电池绿色能源产业共谋发展。
