Multi-layer reflective plastic composite rainbow film made

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

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 together with Zhejiang Yiwu Wanhe Packaging Material Co., Ltd., successfully solved the related technologies in the implementation of the industrialization of rainbow film, and built up to six varieties with a width of 800mm and 1100mm. 20-50 micron rainbow film production line.

Relevant experts stated that the multi-layer plastic composite rainbow film project completed by Beijing Technology and Business University and Zhejiang Yiwu Wanhe Packaging Materials Co., Ltd. fills the blank of domestic rainbow film production technology, and the process technology reaches the advanced level of similar international technologies. It contains no toxic or hazardous chemicals, no waste water, no exhaust gas, and recycling of waste materials. It complies with national industrial policies and environmental protection policies, and has good economic, social and environmental benefits.
