PVC plastic film means a film , polyethylene, polypropylene, polystyrene and other resin, used for packaging, and as coating layer . “Twelve Five” period, especially plastic films feature film materials in emerging industries will play an important role , excellent functional properties of thin film materials , the downstream market segments targeted, broad application prospects. Water film solar cell membrane , a thin film flat panel display , semiconductor and microelectronics films will have a vast space. Functional film materials technology barriers, the main difficulty lies in its formulation, process and equipment. plastic packaging Among the many features of the film , the integrated market space and technical barriers , our most promising optical films and photovoltaic films. Optical grade PET plastic packaging box as the main raw material of the optical film , clear plastic packaging diffusion film, a brightness enhancement film are processed on the basis of the slice from plastic packaging design the PET . Due to the high levels of optical plastic trays thin-film technology , a technology-intensive industries, high barriers to pvc tray entry , is still mainly rely on imports. Now there are companies wishing to enter the domestic optical film field , the domestic enterprises to enter the field of optical films , will boost demand optical PET film. Optical PET film production is mainly concentrated in the Japanese and Korean companies , domestic enterprises have yet to achieve large-scale production plastic box design . East wood science and technology , Nanyang Technology ( 002389 ) is expected to lead a breakthrough. Solar films including film and EVA film backplane backplane film mainly made ??of a fluorine -based film and a polyester film. Fluorinated membranes highest technical barriers , China is still not industrial enterprises, the clamshell packaging relative maturity of the polyester film is slightly higher domestic East wood science and technology , Changzhou Yuxing ‘s products have been certified by the downstream large foreign clients , import substitution is increasingly obvious, large southeast , binary new material, Nanyang Technological also actively entered the field.
