優勢效果

密封的好壞直接影響(xiang)包(bao)(bao)裝效果(guo)、包(bao)(bao)裝物(wu)的貯存和壽命(ming)，甚至還(huan)影響(xiang)包(bao)(bao)裝物(wu)的信譽。為(wei)此，密封膠水(shui)成為(wei)了包(bao)(bao)裝領域的重要組(zu)成部分。

按照密(mi)封(feng)(feng)材(cai)料的(de)形態(tai)和使用方式，大致可分為墊圈密(mi)封(feng)(feng)、膠帶密(mi)封(feng)(feng)和膠體密(mi)封(feng)(feng)等三類，均能達到(dao)防止液(ye)體泄漏、阻隔(ge)氧氣(qi)、濕氣(qi)、異味進入，防偽造、偽劣產品的(de)目的(de)。

防(fang)(fang)偽密封(feng)，一(yi)般以熱熔膠點(dian)封(feng)或壓敏(min)膠帶(dai)粘封(feng)，包裝一(yi)旦折除將無法恢復原狀，從而可防(fang)(fang)止偽劣(lie)產品出(chu)現，保護消費者(zhe)利益。
