随着市场经济的不断发展,国内厚型双向拉伸聚酯薄膜也越来越被整个市场所青睐,但是由于这种技术在我国刚刚起步,尽管受到了市场的青睐,但是相比国际上来说,仍然存在着较大的差距。基于此,一种新型的技术应运而生,就是在线涂布技术,通过对这种技术的应用,制造出一种新型的聚脂薄膜。本文通过对国内厚型在线涂布聚酯薄膜主要市场进行相关阐述,并结合国内聚酯薄膜在线涂布技术的生产及发展情况,对在线涂布聚酯薄膜进行了相关分析与探讨。 With the continuous development of the market economy, the domestic thick biaxially oriented polyester film is also increasingly favored by the entire market, but due to this technology has just started in China, despite the favor of the market, but compared to the international , There is still a big gap. Based on this, a new type of technology came into being, that is, online coating technology, through the application of this technology to create a new type of polyester film. In this paper, the main market of domestic thick-coated on-line polyester film is described, and the production and development of the domestic on-line coating technology of polyester film are combined to analyze and discuss on-line coated polyester film.
