Abstract

本发明公开了一种可降解气调的包装袋，该包装袋由包括以下组分和重量比组成的可降解膜制成：聚乙烯醇(PVA)10‑15份：二氧化硅0.1‑0.2份：甘油2‑3份：碳酸钙0.05‑0.2份混合制成的。保鲜时，将新鲜果蔬先放入袋中，扎紧袋口(或热封袋口)，然后置于冷链温度(0‑4℃)下贮藏。该包装袋具有选择性O2/CO2透过性能及透湿性，包装果蔬时，具有自发气调和适度的维持袋内湿度的特性，能够延长果蔬的保鲜期；并且能够在露天自然条件下快速(6个月内)降解，具有环境友好的特点。

Description

一种可降解气调的农产品包装袋
技术领域
本发明涉及一种可降解气调的农产品包装袋。
背景技术
目前的农产品包装袋的种类较多，比如，聚乙烯(PE)袋、聚丙烯(PP)袋、聚对苯二甲酸乙二醇酯(PET)袋等。所有的这些包装袋都很难自然降解，严重污染环境。也有的可降解包装袋但却无气调功能，不适合包装农产品。因此，研发既有气调保鲜功能、又能够自然降解的包装袋是大势所趋。
发明内容
本发明所要解决的技术问题，就是提供一种可以自然降解的可降解气调的农产品包装袋。
解决上述技术问题，本发明所采用的技术方案如下：
一种可降解气调的农产品包装袋，其特征是：所述的包装袋由包括以下组分和重量比的可降解膜制成：聚乙烯醇(PVA)10-15份：二氧化硅0.1-0.2份：甘油2-3份：碳酸钙0.05-0.2份混合制成的。
优选地，所述的包装袋由包括以下组分和重量比的可降解膜制作而成：聚乙烯醇(PVA)15份：二氧化硅0.2份：甘油3份：碳酸钙0.1份混合制成的。
所述的新型可降解气调包装袋使用时，将新鲜果蔬先放入袋中，扎紧袋口；然后放置冷链温度(0-4℃)下贮藏。
有益效果：采用本发明的新型可降解气调包装袋去进行果蔬保鲜，既能使得O2/CO2透过性好也可实现透湿性好，对果蔬会起到更好的保鲜效果，同时也能够在露天自然条件下快速(6个月内)降解，具有环境友好的特点。
具体实施方式
下面结合具体实施例对本发明做进一步的详细说明。
本发明的新型可降解气调包装袋实施例，采用的包装袋由可降解膜制作而成，所述的可降解膜包括以下组分和重量比的：
聚乙烯醇(PVA)15份：二氧化硅0.2份：甘油3份：碳酸钙0.1份混合制成的。
使用所述包装袋的果蔬保鲜方法实施例如下。
实施例1，步骤如下：
1)将5kg火龙果放入“长×宽＝50cm×30cm”袋中，袋口扎紧；
2)将装有火龙果的保鲜袋置于4℃下贮藏。
实施例2，步骤如下：
1)将3kg菜心放入“长×宽＝50cm×30cm”袋中，袋口扎紧；
2)将装有菜心的保鲜袋置于4℃下贮藏。
采用的包装袋由可降解膜制作而成，可降解膜包括以下组分和重量比的：
聚乙烯醇(PVA)12份：二氧化硅0.15份：甘油2.5份：碳酸钙0.15份混合制成的。
