中文摘要：

多糖类可食用膜是多糖类大分子物质溶于溶剂中，通过分子内和分子间作用力形成的具有网状结构的薄膜。多糖类可食用膜主要特点是生物可降解性和可食性，可以作为传统包装膜的替代品。文章介绍多糖可食用膜的性能特点、成膜材料、增塑剂及其应用现状，提出未来多糖类可食用膜的商业化发展趋势。

英文摘要：

Polysaccharide edible film, an layer of mesh structural film, is formed through intramolecular and intermolecular force of polymers. The main feature of polysaccharide based edible film is the biodegradability and edibility, and it can be as an alternative to traditional packaging film. The performances, film forming materials, plasticizers and the application of polysaccharides based films have been introduced, moreover, the trend of commercial development in the future have been put forward.
