保(bao)鮮膜在生產過程(cheng)中普遍添加了塑化劑，保(bao)鮮膜對人(ren)體健康的影響也(ye)受(shou)到(dao)了人(ren)們(men)的關注。

市場上的保(bao)(bao)(bao)鮮(xian)膜大體(ti)分(fen)為兩類(lei)，一(yi)(yi)類(lei)是(shi)普(pu)通保(bao)(bao)(bao)鮮(xian)膜，適用于(yu)冰(bing)箱保(bao)(bao)(bao)鮮(xian)；一(yi)(yi)類(lei)是(shi)微波(bo)爐保(bao)(bao)(bao)鮮(xian)膜，既可用于(yu)冰(bing)箱保(bao)(bao)(bao)鮮(xian)，也可用于(yu)微波(bo)爐。后一(yi)(yi)種保(bao)(bao)(bao)鮮(xian)膜在耐(nai)熱、無毒性等方(fang)面遠(yuan)遠(yuan)優于(yu)普(pu)通保(bao)(bao)(bao)鮮(xian)膜。因此，消費者(zhe)在使用選擇上要特別注意，分(fen)項使用。

購(gou)買保(bao)(bao)(bao)鮮(xian)(xian)(xian)膜時，首先建(jian)議購(gou)買聚乙烯(xi)（PE）材(cai)質制成(cheng)(cheng)的(de)(de)(de)(de)自(zi)粘(zhan)保(bao)(bao)(bao)鮮(xian)(xian)(xian)膜，尤其(qi)是在(zai)為(wei)肉食(shi)、水果等進行保(bao)(bao)(bao)鮮(xian)(xian)(xian)時，因為(wei)從安全性(xing)(xing)上來(lai)講(jiang)，PE材(cai)質的(de)(de)(de)(de)保(bao)(bao)(bao)鮮(xian)(xian)(xian)膜是最安全的(de)(de)(de)(de)。如果希望保(bao)(bao)(bao)鮮(xian)(xian)(xian)期(qi)較長(chang)，建(jian)議選擇(ze)聚偏二氯(lv)乙烯(xi)（PVDC），因為(wei)這(zhe)種材(cai)質的(de)(de)(de)(de)保(bao)(bao)(bao)鮮(xian)(xian)(xian)膜保(bao)(bao)(bao)濕性(xing)(xing)能比較好(hao)，在(zai)三種材(cai)質的(de)(de)(de)(de)保(bao)(bao)(bao)鮮(xian)(xian)(xian)膜中保(bao)(bao)(bao)鮮(xian)(xian)(xian)期(qi)最長(chang)。聚氯(lv)乙烯(xi)（PVC）材(cai)質的(de)(de)(de)(de)保(bao)(bao)(bao)鮮(xian)(xian)(xian)膜由于透(tou)明度(du)(du)好(hao)、粘(zhan)度(du)(du)好(hao)、彈(dan)性(xing)(xing)好(hao)，價格較為(wei)便(bian)宜，所以也(ye)成(cheng)(cheng)為(wei)很多人的(de)(de)(de)(de)選擇(ze)，但一定(ding)要注意不能用(yong)來(lai)做油脂(zhi)食(shi)品(pin)的(de)(de)(de)(de)保(bao)(bao)(bao)鮮(xian)(xian)(xian)
