Description

一种果蔬保鲜膜及其制备方法
技术领域
本发明涉及薄膜领域，具体涉及一种果蔬保鲜膜及其制备方法。
背景技术
目前市场上水果和蔬菜包装用聚丙烯薄膜容易受到温度、湿度的激烈变化和包装物品含有水分的蒸发(散发)，很容易在薄膜的表面形成结雾状(水滴)，这种形成的雾状，会影响到包装物的外观进而影响到商品的价值，还有落下的水滴会造成新鲜果蔬的变色乃至腐烂变质。随着科学技术的进步，对果蔬保鲜膜的要求越来越高，各种新型保鲜膜不断出现。
发明内容
本发明的目的在于提供一种防雾性能好、抗静电高的果蔬保鲜膜及其制备方法。
上述目的通过以下技术方案实现：
一种果蔬保鲜膜，由下列重量份的原料制得：改性聚乙烯树脂70-85、防雾母粒10-12、乙烯-醋酸乙烯树脂30-45、抗静电剂5-8、抗氧剂3-4、石蜡2-3。
一种果蔬保鲜膜的制备方法，包括如下步骤：采用上述配比取改性聚乙烯树脂、防雾母粒、乙烯-醋酸乙烯树脂、抗静电剂、抗氧剂、石蜡，通过挤出或挤出吹塑工艺进行熔融、混炼、挤出、冷却、干燥、切粒后，吹膜即得果蔬保鲜膜。
采取上述技术方案后，由于本发明使用了改性聚乙烯树脂，与其他原料相容性好，所得薄膜防雾性能好、抗静电高。采用该薄膜对水果和蔬菜贮藏保鲜膜时，其气调指标稳定，对Ｏ2和ＣＯ2的双向调节能力强，对有害气体置换能力强，透湿性好，不易内结露，使用其贮藏果蔬保鲜的时间长，保鲜效果好。
以下通过实施例形式的具体实施方式，对本发明的上述内容再作进一步的详细说明，但不应理解为本发明上述主题的范围仅限于以下的实施例，凡基于本发明上述内容所实现的技术均属于本发明的范围。
具体实施方式
下面结合具体实施例对本发明一种果蔬保鲜膜及其制备方法作进一行说明：
一种果蔬保鲜膜，由下述重量（kg）的原料制得：改性聚乙烯树脂70、防雾母粒10、乙烯-醋酸乙烯树脂30、抗静电剂5、抗氧剂3、石蜡2。
一种果蔬保鲜膜的制备方法，包括如下步骤：
采用上述配比取改性聚乙烯树脂、防雾母粒、乙烯-醋酸乙烯树脂、抗静电剂、抗氧剂、石蜡，通过挤出或挤出吹塑工艺进行熔融、混炼、挤出、冷却、干燥、切粒后，吹膜即得果蔬保鲜膜。

Claims (2)

1.一种果蔬保鲜膜，由下列重量份原料组成：改性聚乙烯树脂70-85、防雾母粒10-12、乙烯-醋酸乙烯树脂30-45、抗静电剂5-8、抗氧剂3-4、石蜡2-3。
2.根据权利要求1所述的果蔬保鲜膜的制备方法，其制备方法为：采用上述配比取改性聚乙烯树脂、防雾母粒、乙烯-醋酸乙烯树脂、抗静电剂、抗氧剂、石蜡，通过挤出或挤出吹塑工艺进行熔融、混炼、挤出、冷却、干燥、切粒后，吹膜即得果蔬保鲜膜。
