保鮮膜在生(sheng)產過程中(zhong)普遍添加了(le)(le)塑化劑，保鮮膜對人體(ti)健(jian)康(kang)的(de)影響也受到了(le)(le)人們的(de)關注。

市場(chang)上的保(bao)(bao)鮮(xian)(xian)膜(mo)(mo)大體分(fen)為兩類，一類是普(pu)通保(bao)(bao)鮮(xian)(xian)膜(mo)(mo)，適用(yong)于冰箱(xiang)保(bao)(bao)鮮(xian)(xian)；一類是微波(bo)爐(lu)保(bao)(bao)鮮(xian)(xian)膜(mo)(mo)，既可用(yong)于冰箱(xiang)保(bao)(bao)鮮(xian)(xian)，也可用(yong)于微波(bo)爐(lu)。后一種(zhong)保(bao)(bao)鮮(xian)(xian)膜(mo)(mo)在(zai)耐熱、無毒(du)性等方面遠遠優于普(pu)通保(bao)(bao)鮮(xian)(xian)膜(mo)(mo)。因(yin)此，消(xiao)費者在(zai)使(shi)用(yong)選擇(ze)上要特(te)別(bie)注意，分(fen)項(xiang)使(shi)用(yong)。

購買保(bao)(bao)(bao)鮮(xian)(xian)(xian)膜(mo)時(shi)，首先建議(yi)購買聚乙烯(xi)（PE）材質(zhi)制(zhi)成的自粘保(bao)(bao)(bao)鮮(xian)(xian)(xian)膜(mo)，尤其是在(zai)為肉食(shi)、水果等進行保(bao)(bao)(bao)鮮(xian)(xian)(xian)時(shi)，因(yin)為從安全性(xing)上來講，PE材質(zhi)的保(bao)(bao)(bao)鮮(xian)(xian)(xian)膜(mo)是最(zui)(zui)安全的。如果希望保(bao)(bao)(bao)鮮(xian)(xian)(xian)期較(jiao)(jiao)長(chang)，建議(yi)選擇聚偏二氯乙烯(xi)（PVDC），因(yin)為這(zhe)種材質(zhi)的保(bao)(bao)(bao)鮮(xian)(xian)(xian)膜(mo)保(bao)(bao)(bao)濕性(xing)能(neng)比較(jiao)(jiao)好(hao)，在(zai)三(san)種材質(zhi)的保(bao)(bao)(bao)鮮(xian)(xian)(xian)膜(mo)中保(bao)(bao)(bao)鮮(xian)(xian)(xian)期最(zui)(zui)長(chang)。聚氯乙烯(xi)（PVC）材質(zhi)的保(bao)(bao)(bao)鮮(xian)(xian)(xian)膜(mo)由于(yu)透明度(du)好(hao)、粘度(du)好(hao)、彈性(xing)好(hao)，價格較(jiao)(jiao)為便(bian)宜，所以也(ye)成為很多(duo)人的選擇，但一定(ding)要(yao)注意不能(neng)用來做油脂食(shi)品的保(bao)(bao)(bao)鮮(xian)(xian)(xian)
