真空(kong)包裝機廠的(de)真(zhen)空包(bao)裝機增加充(chong)(chong)氣(qi)(qi)功能是(shi)(shi)有兩種(zhong)(zhong)方(fang)(fang)式，一(yi)種(zhong)(zhong)是(shi)(shi)氣(qi)(qi)嘴(zui)直接伸到(dao)(dao)產(chan)(chan)品袋子(zi)里面進行充(chong)(chong)氣(qi)(qi)的(de)，另一(yi)種(zhong)(zhong)是(shi)(shi)把要(yao)充(chong)(chong)的(de)氣(qi)(qi)體(ti)先充(chong)(chong)滿整個(ge)真(zhen)空室，然后靠負壓(ya)差(cha)充(chong)(chong)滿袋子(zi)。那究竟采用(yong)(yong)哪(na)種(zhong)(zhong)方(fang)(fang)式充(chong)(chong)氣(qi)(qi)好(hao)呢，這里主要(yao)看(kan)客戶(hu)的(de)產(chan)(chan)品性(xing)質，單純(chun)來說肯定是(shi)(shi)直接沖到(dao)(dao)袋子(zi)里比(bi)較好(hao)，這樣置換的(de)又(you)純(chun)還能省不少氣(qi)(qi)源，但(dan)是(shi)(shi)大家一(yi)定要(yao)考慮好(hao)自己產(chan)(chan)品性(xing)質。如(ru)果(guo)產(chan)(chan)品是(shi)(shi)顆粒，我們可以采取起(qi)初一(yi)種(zhong)(zhong)方(fang)(fang)法直接讓充(chong)(chong)氣(qi)(qi)嘴(zui)到(dao)(dao)袋子(zi)里進行充(chong)(chong)氣(qi)(qi)，但(dan)是(shi)(shi)如(ru)果(guo)你的(de)產(chan)(chan)品是(shi)(shi)粉(fen)末狀(zhuang)的(de)就不能用(yong)(yong)起(qi)初一(yi)種(zhong)(zhong)方(fang)(fang)法了，需(xu)要(yao)第二種(zhong)(zhong)在真(zhen)空室充(chong)(chong)氣(qi)(qi)利(li)用(yong)(yong)壓(ya)力差(cha)充(chong)(chong)滿袋子(zi)。可是(shi)(shi)客戶(hu)又(you)要(yao)要(yao)求達到(dao)(dao)一(yi)定比(bi)例的(de)殘氧量，這就很矛盾了。
