保(bao)鮮膜(mo)在(zai)生產(chan)過程中普遍添加了(le)塑化劑(ji)，保(bao)鮮膜(mo)對人體(ti)健康的(de)影響也(ye)受到(dao)了(le)人們的(de)關注。

市(shi)場上的保(bao)鮮(xian)(xian)(xian)膜大體分(fen)(fen)為兩類，一類是(shi)普通(tong)保(bao)鮮(xian)(xian)(xian)膜，適用(yong)(yong)于冰箱保(bao)鮮(xian)(xian)(xian)；一類是(shi)微波爐保(bao)鮮(xian)(xian)(xian)膜，既(ji)可(ke)用(yong)(yong)于冰箱保(bao)鮮(xian)(xian)(xian)，也(ye)可(ke)用(yong)(yong)于微波爐。后(hou)一種保(bao)鮮(xian)(xian)(xian)膜在(zai)耐熱、無毒性等方面遠遠優于普通(tong)保(bao)鮮(xian)(xian)(xian)膜。因此，消費者在(zai)使用(yong)(yong)選擇上要特別(bie)注意，分(fen)(fen)項(xiang)使用(yong)(yong)。

購買保(bao)(bao)(bao)(bao)鮮(xian)(xian)(xian)(xian)膜(mo)(mo)時(shi)，首先建議購買聚乙(yi)(yi)烯(xi)(xi)（PE）材(cai)質制成(cheng)的(de)自粘保(bao)(bao)(bao)(bao)鮮(xian)(xian)(xian)(xian)膜(mo)(mo)，尤(you)其是在(zai)為(wei)肉食、水果(guo)等進行(xing)保(bao)(bao)(bao)(bao)鮮(xian)(xian)(xian)(xian)時(shi)，因為(wei)從(cong)安(an)全性(xing)(xing)上(shang)來講，PE材(cai)質的(de)保(bao)(bao)(bao)(bao)鮮(xian)(xian)(xian)(xian)膜(mo)(mo)是最安(an)全的(de)。如果(guo)希望保(bao)(bao)(bao)(bao)鮮(xian)(xian)(xian)(xian)期較長，建議選(xuan)擇聚偏(pian)二氯乙(yi)(yi)烯(xi)(xi)（PVDC），因為(wei)這種材(cai)質的(de)保(bao)(bao)(bao)(bao)鮮(xian)(xian)(xian)(xian)膜(mo)(mo)保(bao)(bao)(bao)(bao)濕性(xing)(xing)能(neng)比較好(hao)(hao)，在(zai)三種材(cai)質的(de)保(bao)(bao)(bao)(bao)鮮(xian)(xian)(xian)(xian)膜(mo)(mo)中保(bao)(bao)(bao)(bao)鮮(xian)(xian)(xian)(xian)期最長。聚氯乙(yi)(yi)烯(xi)(xi)（PVC）材(cai)質的(de)保(bao)(bao)(bao)(bao)鮮(xian)(xian)(xian)(xian)膜(mo)(mo)由(you)于透明度好(hao)(hao)、粘度好(hao)(hao)、彈性(xing)(xing)好(hao)(hao)，價格較為(wei)便宜(yi)，所以也成(cheng)為(wei)很多人(ren)的(de)選(xuan)擇，但(dan)一(yi)定(ding)要注(zhu)意不(bu)能(neng)用來做油(you)脂(zhi)食品的(de)保(bao)(bao)(bao)(bao)鮮(xian)(xian)(xian)(xian)
