保(bao)鮮(xian)膜在(zai)生(sheng)產(chan)過程中普遍添加了(le)塑化劑，保(bao)鮮(xian)膜對人體(ti)健(jian)康的影響也(ye)受到了(le)人們(men)的關注(zhu)。

市(shi)場上(shang)的保鮮(xian)膜大(da)體分為兩類(lei)，一類(lei)是普通(tong)保鮮(xian)膜，適用(yong)(yong)于(yu)冰(bing)箱(xiang)(xiang)保鮮(xian)；一類(lei)是微波爐(lu)保鮮(xian)膜，既可(ke)(ke)用(yong)(yong)于(yu)冰(bing)箱(xiang)(xiang)保鮮(xian)，也(ye)可(ke)(ke)用(yong)(yong)于(yu)微波爐(lu)。后一種保鮮(xian)膜在(zai)耐熱、無(wu)毒性等(deng)方面(mian)遠遠優于(yu)普通(tong)保鮮(xian)膜。因此(ci)，消費者(zhe)在(zai)使用(yong)(yong)選擇上(shang)要特別注意，分項使用(yong)(yong)。

購(gou)買(mai)保(bao)(bao)(bao)(bao)鮮(xian)膜(mo)時，首先建(jian)議(yi)購(gou)買(mai)聚(ju)(ju)乙烯(xi)（PE）材(cai)(cai)質(zhi)制(zhi)成的(de)自粘保(bao)(bao)(bao)(bao)鮮(xian)膜(mo)，尤其是在為(wei)(wei)肉食(shi)、水果等(deng)進(jin)行保(bao)(bao)(bao)(bao)鮮(xian)時，因為(wei)(wei)從安全(quan)性(xing)(xing)(xing)上來講，PE材(cai)(cai)質(zhi)的(de)保(bao)(bao)(bao)(bao)鮮(xian)膜(mo)是最安全(quan)的(de)。如果希望(wang)保(bao)(bao)(bao)(bao)鮮(xian)期較(jiao)長，建(jian)議(yi)選(xuan)擇(ze)(ze)聚(ju)(ju)偏(pian)二氯(lv)(lv)乙烯(xi)（PVDC），因為(wei)(wei)這種(zhong)材(cai)(cai)質(zhi)的(de)保(bao)(bao)(bao)(bao)鮮(xian)膜(mo)保(bao)(bao)(bao)(bao)濕性(xing)(xing)(xing)能(neng)比較(jiao)好(hao)(hao)，在三(san)種(zhong)材(cai)(cai)質(zhi)的(de)保(bao)(bao)(bao)(bao)鮮(xian)膜(mo)中保(bao)(bao)(bao)(bao)鮮(xian)期最長。聚(ju)(ju)氯(lv)(lv)乙烯(xi)（PVC）材(cai)(cai)質(zhi)的(de)保(bao)(bao)(bao)(bao)鮮(xian)膜(mo)由于透(tou)明度好(hao)(hao)、粘度好(hao)(hao)、彈性(xing)(xing)(xing)好(hao)(hao)，價格較(jiao)為(wei)(wei)便宜，所以也成為(wei)(wei)很多人的(de)選(xuan)擇(ze)(ze)，但(dan)一定要注意不能(neng)用來做油脂食(shi)品的(de)保(bao)(bao)(bao)(bao)鮮(xian)
