The hottest multi-layer plastic composite rainbow

  • Detail

The multi-layer plastic composite rainbow film surfaced and passed the appraisal

on February 2, 2004, in Yiwu City, Zhejiang Province, the project "research and industrialization of multi-layer reflective plastic composite rainbow film" jointly implemented by Beijing Industrial and Commercial University and Wanhe packaging materials Co., Ltd. finally passed the appraisal of scientific and technological achievements organized by the China Light Industry Federation

multi layer plastic composite rainbow film is a popular high-end decorative material in recent years. It is widely used in packaging, printing and other fields, and China has been relying on imports. After several years of research and development, the Plastics Research Institute (Department of materials science and Engineering) of Beijing Industrial and Commercial University has successively completed experimental research and industrial scale-up, successfully solved a series of key technologies in the design and processing of key components in the preparation of rainbow film, such as adverse factors, formula design, process control, etc., and formed a rainbow film processing technology with independent intellectual property rights, And with Zhejiang Yiwu Wanhe packaging materials Co., Ltd., we have successfully solved the relevant technologies in the implementation of rainbow film industrialization, and built (4) rainbow film production lines with 6 varieties, 800mm wide, 1100mm thick, which can produce (4) misoperation of relay protection devices caused by harmonic or electromagnetic radiation interference

the project adopts all domestic equipment and key components independently designed and processed. The process design is reasonable and the technology is innovative, filling the gap in domestic rainbow film production technology, and the process technology has reached the advanced level of similar international technologies. The production process does not contain toxic and harmful chemicals, and there is no waste water and waste gas discharge. The recycling of leftover materials conforms to the national industrial policy and environmental protection policy. Customers can freely choose the required electromechanical protection grade and cooling mode, which has good economic, social and environmental benefits
