保(bao)鮮(xian)(xian)膜(mo)在生產過程(cheng)中普遍添加了塑化劑，保(bao)鮮(xian)(xian)膜(mo)對人體健康的影響(xiang)也受(shou)到了人們的關注。

市場上(shang)的(de)保鮮(xian)(xian)膜大體分為兩類(lei)，一(yi)類(lei)是(shi)普通(tong)保鮮(xian)(xian)膜，適用(yong)(yong)于冰箱保鮮(xian)(xian)；一(yi)類(lei)是(shi)微波(bo)爐保鮮(xian)(xian)膜，既可用(yong)(yong)于冰箱保鮮(xian)(xian)，也可用(yong)(yong)于微波(bo)爐。后一(yi)種保鮮(xian)(xian)膜在耐熱、無毒性等方面遠(yuan)遠(yuan)優(you)于普通(tong)保鮮(xian)(xian)膜。因(yin)此，消費者在使用(yong)(yong)選擇上(shang)要特別注意，分項使用(yong)(yong)。

購(gou)買保(bao)(bao)(bao)(bao)(bao)鮮(xian)膜(mo)(mo)時，首先建(jian)議(yi)購(gou)買聚乙(yi)烯（PE）材(cai)質(zhi)制成的自粘(zhan)保(bao)(bao)(bao)(bao)(bao)鮮(xian)膜(mo)(mo)，尤其(qi)是在為(wei)肉食、水果等進行(xing)保(bao)(bao)(bao)(bao)(bao)鮮(xian)時，因為(wei)從安全性上來(lai)講，PE材(cai)質(zhi)的保(bao)(bao)(bao)(bao)(bao)鮮(xian)膜(mo)(mo)是最(zui)安全的。如果希望保(bao)(bao)(bao)(bao)(bao)鮮(xian)期(qi)較(jiao)長(chang)，建(jian)議(yi)選擇聚偏二氯乙(yi)烯（PVDC），因為(wei)這種(zhong)材(cai)質(zhi)的保(bao)(bao)(bao)(bao)(bao)鮮(xian)膜(mo)(mo)保(bao)(bao)(bao)(bao)(bao)濕性能比(bi)較(jiao)好(hao)，在三種(zhong)材(cai)質(zhi)的保(bao)(bao)(bao)(bao)(bao)鮮(xian)膜(mo)(mo)中保(bao)(bao)(bao)(bao)(bao)鮮(xian)期(qi)最(zui)長(chang)。聚氯乙(yi)烯（PVC）材(cai)質(zhi)的保(bao)(bao)(bao)(bao)(bao)鮮(xian)膜(mo)(mo)由于透明度好(hao)、粘(zhan)度好(hao)、彈(dan)性好(hao)，價格較(jiao)為(wei)便宜，所以(yi)也(ye)成為(wei)很(hen)多人的選擇，但(dan)一定(ding)要注意不能用來(lai)做油脂食品的保(bao)(bao)(bao)(bao)(bao)鮮(xian)
