The "multilayer reflective plastic composite rainbow film research and industrialization" project jointly completed by Beijing Technology and Business University and Zhejiang Yiwu Wanhe Packaging Materials Co., Ltd. was recently organized by China Light Industry Federation in Yiwu, Zhejiang Province. Identification of scientific and technological achievements.

Multi-layer reflective plastic composite rainbow film is a popular high-end decoration and decorating material in recent years, widely used in packaging, printing and other fields, the domestic market has been dependent on imports. After several years of research and development, the Institute of Plastics of Beijing Technology and Business University has completed experimental research and industrial scale-up, successfully solved a series of key technologies such as design, processing, formula design, and process control of key components in the preparation of rainbow film, and formed an autonomous system. Rainbow film processing technology of intellectual property rights, and with Zhejiang Yiwu Wanhe Packaging Materials Co., Ltd. successfully solved the related technology in the implementation of rainbow film industrialization, and built up to six varieties, width 800 mm, 1100 mm, thickness 20 to 50 micron rainbow film production line.

Beijing Technology and Business University and Zhejiang Yiwu Wanhe Packaging Materials Co., Ltd. multi-layer plastic composite rainbow film project fills the blank of domestic rainbow film production technology, and the process technology reaches the advanced level of international similar technologies, and the production process does not contain toxic and hazardous chemicals. Products, no waste water, exhaust emissions, recycling scrap, in line with national industrial policies and environmental protection policies, with good economic, social and environmental benefits.
