保(bao)鮮膜在生(sheng)產過程(cheng)中普遍添加了塑化劑,保(bao)鮮膜對人體健康的(de)影(ying)響也(ye)受到了人們的(de)關注(zhu)。
市場上的保(bao)鮮(xian)膜大體分為兩類(lei),一類(lei)是普通(tong)保(bao)鮮(xian)膜,適用(yong)(yong)于(yu)冰箱(xiang)保(bao)鮮(xian);一類(lei)是微波爐保(bao)鮮(xian)膜,既可(ke)用(yong)(yong)于(yu)冰箱(xiang)保(bao)鮮(xian),也可(ke)用(yong)(yong)于(yu)微波爐。后(hou)一種保(bao)鮮(xian)膜在耐熱、無毒性等方面遠遠優于(yu)普通(tong)保(bao)鮮(xian)膜。因此(ci),消費者在使用(yong)(yong)選擇上要特(te)別注(zhu)意(yi),分項使用(yong)(yong)。
購(gou)買(mai)保(bao)(bao)(bao)鮮(xian)膜(mo)(mo)時(shi),首(shou)先建議購(gou)買(mai)聚乙(yi)烯(PE)材質制成的(de)(de)自粘保(bao)(bao)(bao)鮮(xian)膜(mo)(mo),尤其是(shi)在為(wei)肉(rou)食、水(shui)果(guo)(guo)等(deng)進行(xing)保(bao)(bao)(bao)鮮(xian)時(shi),因為(wei)從安全性(xing)上來講,PE材質的(de)(de)保(bao)(bao)(bao)鮮(xian)膜(mo)(mo)是(shi)最安全的(de)(de)。如果(guo)(guo)希望保(bao)(bao)(bao)鮮(xian)期(qi)較長,建議選擇聚偏二(er)氯(lv)乙(yi)烯(PVDC),因為(wei)這(zhe)種(zhong)材質的(de)(de)保(bao)(bao)(bao)鮮(xian)膜(mo)(mo)保(bao)(bao)(bao)濕(shi)性(xing)能比較好(hao),在三種(zhong)材質的(de)(de)保(bao)(bao)(bao)鮮(xian)膜(mo)(mo)中保(bao)(bao)(bao)鮮(xian)期(qi)最長。聚氯(lv)乙(yi)烯(PVC)材質的(de)(de)保(bao)(bao)(bao)鮮(xian)膜(mo)(mo)由(you)于透明度(du)好(hao)、粘度(du)好(hao)、彈性(xing)好(hao),價格(ge)較為(wei)便宜,所(suo)以也成為(wei)很多人的(de)(de)選擇,但一(yi)定要注意不(bu)能用來做油脂食品的(de)(de)保(bao)(bao)(bao)鮮(xian)
