保鮮膜(mo)在(zai)生產過程(cheng)中普遍添加(jia)了塑化劑，保鮮膜(mo)對人體健康的影(ying)響也受到了人們的關(guan)注。

市(shi)場(chang)上的保(bao)(bao)(bao)鮮(xian)(xian)(xian)膜大體分為(wei)兩類，一類是普(pu)通保(bao)(bao)(bao)鮮(xian)(xian)(xian)膜，適用(yong)(yong)于冰箱保(bao)(bao)(bao)鮮(xian)(xian)(xian)；一類是微波爐保(bao)(bao)(bao)鮮(xian)(xian)(xian)膜，既可用(yong)(yong)于冰箱保(bao)(bao)(bao)鮮(xian)(xian)(xian)，也可用(yong)(yong)于微波爐。后一種(zhong)保(bao)(bao)(bao)鮮(xian)(xian)(xian)膜在耐熱、無毒(du)性等方(fang)面(mian)遠(yuan)遠(yuan)優于普(pu)通保(bao)(bao)(bao)鮮(xian)(xian)(xian)膜。因此(ci)，消(xiao)費者在使用(yong)(yong)選擇上要特(te)別注(zhu)意，分項使用(yong)(yong)。

購買(mai)保(bao)(bao)鮮(xian)膜(mo)時，首先建(jian)議(yi)(yi)購買(mai)聚乙烯（PE）材(cai)質制成的自粘保(bao)(bao)鮮(xian)膜(mo)，尤其(qi)是在為(wei)肉食(shi)、水果(guo)等(deng)進行保(bao)(bao)鮮(xian)時，因為(wei)從安全(quan)性上來講(jiang)，PE材(cai)質的保(bao)(bao)鮮(xian)膜(mo)是最安全(quan)的。如果(guo)希望保(bao)(bao)鮮(xian)期較長，建(jian)議(yi)(yi)選擇(ze)聚偏二氯乙烯（PVDC），因為(wei)這種材(cai)質的保(bao)(bao)鮮(xian)膜(mo)保(bao)(bao)濕性能比(bi)較好，在三(san)種材(cai)質的保(bao)(bao)鮮(xian)膜(mo)中保(bao)(bao)鮮(xian)期最長。聚氯乙烯（PVC）材(cai)質的保(bao)(bao)鮮(xian)膜(mo)由于透(tou)明度好、粘度好、彈性好，價格較為(wei)便宜(yi)，所以也成為(wei)很多人的選擇(ze)，但一定(ding)要(yao)注(zhu)意不(bu)能用來做油脂食(shi)品的保(bao)(bao)鮮(xian)
