Functional thin film clear plastic box materials import substitution has become increasingly evidentPVC 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. 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 as the main raw material of the optical film , diffusion film, a brightness enhancement film are processed on the basis of the slice from the PET . Due to the high levels of optical thin-film technology , a technology-intensive industries, high barriers clamshell boxes to 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 , plastic packaging box will boost demand optical PET film. Optical PET film production is mainly concentrated in the Japanese and Korean companies , domestic enterprises have yet packaging boxes wholesale to achieve large-scale production . East wood science and technology , Nanyang Technological breakthrough is expected to take the lead .Solar films including film and EVA film backplane backplane film clear plastic box packagingblister packs packaging mainly made ??of a fluorine -based film and a polyester film. Fluorinated membranes highest technical barriers , China is still not industrial enterprises, the relative maturity of the polyester film is slightly higher domestic clam shells for sale 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.
