摘要
水溶性聚乙烯醇薄膜是一种新型绿色包装材料,它在水溶性、阻隔性和环保性等方面的独特优点使其成为目前国内外包装业的研究热点。介绍了水溶性聚乙烯醇薄膜的主要成分和生产工艺,提出了由于大量分子内和分子间氢键导致聚乙烯醇薄膜的水溶性和热塑性问题,进而阐述了对聚乙烯醇薄膜水溶性和热塑性的改性技术,最后概述了聚乙烯醇薄膜的国内外研究进展,并展望了其广阔的应用前景。
Water-soluble polyvinyl alcohol film is a novel green packaging material. It is known as a research focus in package trade because of its special excellent characteristics in many aspects, such as water solubility, barrier and environment-friendly. The main ingredients and technological methods of the water-soluble polyvinyl alcohol films are introduced. Meanwhile, the problems of the water-soluble and thermoplastic ability of polyvinyl alcohol films are put forward and the modification methods are discussed in detail. At last, the development of polyvinyl alcohol films in and abroad is reviewed and the wild applying prospect is looked forward to.
