Fresh-cut fruits and vegetables are highly perishable commodities. Packaging forms an important tool to maintain the shelf life of packed fresh-cut agricultural produce. Petroleum-based films are conventionally used for fresh fruits and vegetables. However, being nonbiodegradable and derivability from nonrenewable resources, these films lead towards serious ecological problems. To address this issue, various efforts have been focused on renewable and biodegradable films obtained from biopolymers. Widely studied biopolymers for film preparation are derived from biomass (gelatin, starch, cellulose, etc.), microbes (polyhydroxyalkanoates), and bio-derived monomers (polylactic acid). However, such films possess poor mechanical and barrier properties as compared to their commercial counterparts. Incorporation of various additives has been proposed to improve the film characteristics. In the present review, comprehensive information has been provided on different methodologies for film fabrication, properties, and applications of stand-alone bio-based films for packaging of fresh-cut produce. Furthermore, successful commercial implementation of such film is also summarized.

鲜切水果和蔬菜是极易腐烂的商品。包装是保持包装的鲜切农产品的保质期的重要工具。石油基薄膜通常用于新鲜水果和蔬菜。然而，由于这些膜不可生物降解并且可源自不可再生资源，因此导致严重的生态问题。为了解决这个问题，已经将各种努力集中在从生物聚合物获得的可再生和可生物降解的薄膜上。广泛研究的用于薄膜制备的生物聚合物衍生自生物质（明胶，淀粉，纤维素等），微生物（聚羟基链烷酸酯）和生物来源的单体（聚乳酸）。然而，与它们的商业对应物相比，这样的膜具有差的机械和阻挡性能。已提出掺入各种添加剂以改善膜的特性。在本综述中，已提供了有关薄膜制造，特性以及用于包装鲜切农产品的独立生物基薄膜的应用的不同方法的全面信息。此外，还总结了这种膜的成功商业应用。
