塑料包装材料的过度使用和处置对环境和生态系统造成的不利影响越来越引起社会的关注。聚乙烯（PE）薄膜是目前应用最广泛的水果包装材料，但由于其透气性较差，不适合芒果等热带水果的长期保鲜。纤维素基薄膜可以由可再生资源制成，并且是可生物降解和环境友好的，这使得它成为PE作为包装材料的有前途的替代品。本研究以香蕉茎纤维为原料，通过离子液体1-烯丙基-3-甲基咪唑氯化物（[AMIm][Cl]）合成纤维素膜，并将其作为芒果保鲜包装材料进行评价。合成的纤维素膜的水蒸气透过率和气体透过率分别为1，969.1 g/（m2·24 h）和10，015.4 ml/（m2·24 h），其显著高于商业PE膜。高透性有利于乙烯的释放，从而有助于延长果实的后熟期。结果表明，纤维素薄膜包装显著降低了芒果的病害和色泽指数，延长了商品果的贮藏和货架期。此外，纤维素膜在土壤中4周内分解，表明与PE塑料膜相比具有优异的生物降解性。
The excessive use and disposal of plastic packaging materials have drawn increasing concerns from the society because of the detrimental effect on environment and ecosystems. As the most widely used fruit packing material, polyethylene (PE) film is not suitable for long-term preservation of some tropical fruits, such as mangos, due to its inferior gas permeability. Cellulose based film can be made from renewable resources and is biodegradable and environmental-friendly, which makes it a promising alternative to PE as a packaging material. In this study, cellulose film synthesized from delignified banana stem fibers via an ionic liquid 1-Allyl-3-methylimidazolium chloride ([AMIm][Cl]) were evaluated as packing material for mangos preservation. The moisture vapor transmission rate and gas transmission rate of the synthesized cellulose film were 1,969.1 g/(m2⋅24 h) and 10,015.4 ml/(m2⋅24 h), respectively, which are significantly higher than those of commercial PE films. The high permeability is beneficial to the release of ethylene so that contribute to extend fruit ripening period. As a result, cellulose film packaging significantly decreased the disease and color indexes of mangos, while prolonged the storage and shelf life of marketable fruits. In addition, the cellulose film was decomposed in soils in 4 weeks, indicating an excellent biodegradability as compared to the PE plastic film.
