中国聚乙烯醇改性薄膜近20年来发展现状及前景

Recent Development and Prospect of Polyvinyl Alcohol Modified Membrane in China in Recent 20 Years

聚乙烯醇改性水溶膜进入中国市场已经有近20年历史,由于各种限制在中国市场还没有完全推广使用,相反国外一些国家已经在某些应用上采取强制推广,如美国洗衣袋、巴西农药内包装。本文介绍聚乙烯醇改性水溶膜生产工艺的各种划分、发展进程及现状,希望推进中国环保包装材料的发展与推广。

Polyvinyl alcohol modified water soluble membrane has been in the Chinese market for nearly 20 years, because various restrictions have not been fully implemented in the Chinese market. On the contrary, some foreign countries have taken compulsory promotion in some applications, such as the United States laundry bag and Brazil pesticide internal packaging. In this paper, the development, process and present situation of PVA modified water soluble membrane technology are discussed, hoping to promote the development and promotion of China＇s environmental protection packaging materials.
