保鮮膜(mo)在生(sheng)產(chan)過程中普(pu)遍添(tian)加了塑化劑，保鮮膜(mo)對人(ren)體(ti)健(jian)康(kang)的影(ying)響也受到了人(ren)們的關注(zhu)。

市場上的保(bao)鮮(xian)(xian)膜(mo)大體分為兩類，一類是普通保(bao)鮮(xian)(xian)膜(mo)，適用(yong)(yong)于冰(bing)(bing)箱保(bao)鮮(xian)(xian)；一類是微波(bo)爐(lu)保(bao)鮮(xian)(xian)膜(mo)，既可用(yong)(yong)于冰(bing)(bing)箱保(bao)鮮(xian)(xian)，也(ye)可用(yong)(yong)于微波(bo)爐(lu)。后一種保(bao)鮮(xian)(xian)膜(mo)在耐熱、無(wu)毒性等方面遠(yuan)遠(yuan)優于普通保(bao)鮮(xian)(xian)膜(mo)。因(yin)此(ci)，消費(fei)者在使用(yong)(yong)選擇(ze)上要(yao)特別注意，分項使用(yong)(yong)。

購(gou)(gou)買保(bao)(bao)(bao)鮮(xian)(xian)(xian)(xian)(xian)膜(mo)時，首先建議(yi)購(gou)(gou)買聚(ju)(ju)乙烯(xi)（PE）材(cai)(cai)質(zhi)(zhi)制成(cheng)的(de)自(zi)粘保(bao)(bao)(bao)鮮(xian)(xian)(xian)(xian)(xian)膜(mo)，尤其是在為肉(rou)食(shi)、水果等進行保(bao)(bao)(bao)鮮(xian)(xian)(xian)(xian)(xian)時，因(yin)為從安(an)(an)全性(xing)(xing)上來講(jiang)，PE材(cai)(cai)質(zhi)(zhi)的(de)保(bao)(bao)(bao)鮮(xian)(xian)(xian)(xian)(xian)膜(mo)是最(zui)安(an)(an)全的(de)。如果希望保(bao)(bao)(bao)鮮(xian)(xian)(xian)(xian)(xian)期較(jiao)長，建議(yi)選(xuan)擇聚(ju)(ju)偏二氯乙烯(xi)（PVDC），因(yin)為這種材(cai)(cai)質(zhi)(zhi)的(de)保(bao)(bao)(bao)鮮(xian)(xian)(xian)(xian)(xian)膜(mo)保(bao)(bao)(bao)濕性(xing)(xing)能比較(jiao)好(hao)，在三種材(cai)(cai)質(zhi)(zhi)的(de)保(bao)(bao)(bao)鮮(xian)(xian)(xian)(xian)(xian)膜(mo)中保(bao)(bao)(bao)鮮(xian)(xian)(xian)(xian)(xian)期最(zui)長。聚(ju)(ju)氯乙烯(xi)（PVC）材(cai)(cai)質(zhi)(zhi)的(de)保(bao)(bao)(bao)鮮(xian)(xian)(xian)(xian)(xian)膜(mo)由于透(tou)明度(du)好(hao)、粘度(du)好(hao)、彈(dan)性(xing)(xing)好(hao)，價(jia)格較(jiao)為便宜，所以也成(cheng)為很多人的(de)選(xuan)擇，但一定要注意不能用來做油脂食(shi)品的(de)保(bao)(bao)(bao)鮮(xian)(xian)(xian)(xian)(xian)
