保鮮膜(mo)在(zai)生產過程中普遍添(tian)加了塑化(hua)劑，保鮮膜(mo)對人(ren)體健康的(de)影響也受(shou)到了人(ren)們的(de)關(guan)注。

市(shi)場上(shang)的保(bao)鮮(xian)(xian)(xian)膜大(da)體(ti)分為兩類(lei)，一類(lei)是(shi)普(pu)(pu)通(tong)保(bao)鮮(xian)(xian)(xian)膜，適用(yong)(yong)于(yu)(yu)冰箱保(bao)鮮(xian)(xian)(xian)；一類(lei)是(shi)微(wei)波爐(lu)保(bao)鮮(xian)(xian)(xian)膜，既可用(yong)(yong)于(yu)(yu)冰箱保(bao)鮮(xian)(xian)(xian)，也可用(yong)(yong)于(yu)(yu)微(wei)波爐(lu)。后(hou)一種保(bao)鮮(xian)(xian)(xian)膜在耐熱、無毒性等方面(mian)遠遠優于(yu)(yu)普(pu)(pu)通(tong)保(bao)鮮(xian)(xian)(xian)膜。因此，消費者在使用(yong)(yong)選擇(ze)上(shang)要特別(bie)注(zhu)意(yi)，分項(xiang)使用(yong)(yong)。

購(gou)買(mai)保(bao)(bao)(bao)鮮(xian)(xian)膜時，首先建(jian)議購(gou)買(mai)聚(ju)乙烯（PE）材質(zhi)制成的(de)自粘(zhan)保(bao)(bao)(bao)鮮(xian)(xian)膜，尤(you)其是在為(wei)(wei)(wei)肉食、水果等進行保(bao)(bao)(bao)鮮(xian)(xian)時，因(yin)為(wei)(wei)(wei)從安(an)全性(xing)上(shang)來講，PE材質(zhi)的(de)保(bao)(bao)(bao)鮮(xian)(xian)膜是最(zui)安(an)全的(de)。如果希望保(bao)(bao)(bao)鮮(xian)(xian)期較長，建(jian)議選擇(ze)聚(ju)偏二氯(lv)乙烯（PVDC），因(yin)為(wei)(wei)(wei)這種(zhong)材質(zhi)的(de)保(bao)(bao)(bao)鮮(xian)(xian)膜保(bao)(bao)(bao)濕性(xing)能(neng)比較好，在三種(zhong)材質(zhi)的(de)保(bao)(bao)(bao)鮮(xian)(xian)膜中保(bao)(bao)(bao)鮮(xian)(xian)期最(zui)長。聚(ju)氯(lv)乙烯（PVC）材質(zhi)的(de)保(bao)(bao)(bao)鮮(xian)(xian)膜由(you)于(yu)透(tou)明(ming)度(du)好、粘(zhan)度(du)好、彈性(xing)好，價(jia)格較為(wei)(wei)(wei)便宜(yi)，所以也成為(wei)(wei)(wei)很多人的(de)選擇(ze)，但一定要注意不(bu)能(neng)用來做油(you)脂食品的(de)保(bao)(bao)(bao)鮮(xian)(xian)
