保鮮膜在生產過程(cheng)中普遍(bian)添加了塑化劑，保鮮膜對人體健康的影響(xiang)也受到了人們的關注。

市(shi)場上的保(bao)鮮膜(mo)大體分為兩(liang)類(lei)，一(yi)類(lei)是普通保(bao)鮮膜(mo)，適用于冰箱(xiang)保(bao)鮮；一(yi)類(lei)是微波(bo)爐(lu)保(bao)鮮膜(mo)，既(ji)可(ke)(ke)用于冰箱(xiang)保(bao)鮮，也可(ke)(ke)用于微波(bo)爐(lu)。后一(yi)種保(bao)鮮膜(mo)在耐熱、無毒(du)性等方面遠遠優(you)于普通保(bao)鮮膜(mo)。因此，消費者在使(shi)用選擇上要特別注意，分項使(shi)用。

購買保(bao)(bao)(bao)鮮(xian)(xian)(xian)(xian)膜時，首先建議購買聚(ju)(ju)乙烯（PE）材(cai)(cai)質(zhi)制成(cheng)(cheng)的(de)自粘(zhan)(zhan)保(bao)(bao)(bao)鮮(xian)(xian)(xian)(xian)膜，尤(you)其是在為(wei)(wei)肉食(shi)(shi)、水果等(deng)進(jin)行保(bao)(bao)(bao)鮮(xian)(xian)(xian)(xian)時，因為(wei)(wei)從安(an)(an)全(quan)性(xing)上(shang)來講，PE材(cai)(cai)質(zhi)的(de)保(bao)(bao)(bao)鮮(xian)(xian)(xian)(xian)膜是最安(an)(an)全(quan)的(de)。如(ru)果希望保(bao)(bao)(bao)鮮(xian)(xian)(xian)(xian)期(qi)較長，建議選(xuan)擇聚(ju)(ju)偏二氯乙烯（PVDC），因為(wei)(wei)這(zhe)種材(cai)(cai)質(zhi)的(de)保(bao)(bao)(bao)鮮(xian)(xian)(xian)(xian)膜保(bao)(bao)(bao)濕性(xing)能(neng)(neng)比較好(hao)，在三種材(cai)(cai)質(zhi)的(de)保(bao)(bao)(bao)鮮(xian)(xian)(xian)(xian)膜中保(bao)(bao)(bao)鮮(xian)(xian)(xian)(xian)期(qi)最長。聚(ju)(ju)氯乙烯（PVC）材(cai)(cai)質(zhi)的(de)保(bao)(bao)(bao)鮮(xian)(xian)(xian)(xian)膜由于透明度好(hao)、粘(zhan)(zhan)度好(hao)、彈性(xing)好(hao)，價格較為(wei)(wei)便宜，所以也成(cheng)(cheng)為(wei)(wei)很多人(ren)的(de)選(xuan)擇，但一定要注意不能(neng)(neng)用來做(zuo)油脂食(shi)(shi)品(pin)的(de)保(bao)(bao)(bao)鮮(xian)(xian)(xian)(xian)
