保鮮膜(mo)在生產過程中普(pu)遍添加了塑化劑(ji)，保鮮膜(mo)對人體健康的影響也受到(dao)了人們的關注。

市場上的保(bao)鮮(xian)膜(mo)大體(ti)分為兩類(lei)，一(yi)(yi)類(lei)是普(pu)通(tong)保(bao)鮮(xian)膜(mo)，適用(yong)(yong)于冰箱(xiang)保(bao)鮮(xian)；一(yi)(yi)類(lei)是微波(bo)爐(lu)保(bao)鮮(xian)膜(mo)，既可(ke)用(yong)(yong)于冰箱(xiang)保(bao)鮮(xian)，也可(ke)用(yong)(yong)于微波(bo)爐(lu)。后一(yi)(yi)種(zhong)保(bao)鮮(xian)膜(mo)在(zai)耐熱、無毒性等方(fang)面(mian)遠遠優于普(pu)通(tong)保(bao)鮮(xian)膜(mo)。因此，消費者在(zai)使用(yong)(yong)選(xuan)擇上要(yao)特別(bie)注意(yi)，分項使用(yong)(yong)。

購買(mai)保(bao)(bao)(bao)(bao)鮮(xian)(xian)(xian)膜時(shi)，首先(xian)建(jian)議購買(mai)聚(ju)乙(yi)(yi)烯(xi)（PE）材質(zhi)制成的(de)自粘保(bao)(bao)(bao)(bao)鮮(xian)(xian)(xian)膜，尤(you)其是在(zai)為(wei)(wei)肉(rou)食、水果等進(jin)行(xing)保(bao)(bao)(bao)(bao)鮮(xian)(xian)(xian)時(shi)，因為(wei)(wei)從(cong)安(an)全性上來(lai)講，PE材質(zhi)的(de)保(bao)(bao)(bao)(bao)鮮(xian)(xian)(xian)膜是最安(an)全的(de)。如果希望保(bao)(bao)(bao)(bao)鮮(xian)(xian)(xian)期較長(chang)，建(jian)議選擇聚(ju)偏(pian)二氯乙(yi)(yi)烯(xi)（PVDC），因為(wei)(wei)這種材質(zhi)的(de)保(bao)(bao)(bao)(bao)鮮(xian)(xian)(xian)膜保(bao)(bao)(bao)(bao)濕性能(neng)比較好，在(zai)三種材質(zhi)的(de)保(bao)(bao)(bao)(bao)鮮(xian)(xian)(xian)膜中保(bao)(bao)(bao)(bao)鮮(xian)(xian)(xian)期最長(chang)。聚(ju)氯乙(yi)(yi)烯(xi)（PVC）材質(zhi)的(de)保(bao)(bao)(bao)(bao)鮮(xian)(xian)(xian)膜由(you)于透明度好、粘度好、彈性好，價(jia)格較為(wei)(wei)便宜(yi)，所以也成為(wei)(wei)很多人的(de)選擇，但(dan)一(yi)定要注意(yi)不能(neng)用來(lai)做油脂食品的(de)保(bao)(bao)(bao)(bao)鮮(xian)(xian)(xian)
