真空包(bao)裝(zhuang)機(ji)廠的(de)(de)(de)真(zhen)空(kong)(kong)(kong)包裝(zhuang)機(ji)增加(jia)充(chong)(chong)(chong)氣(qi)功能(neng)是(shi)(shi)有兩種(zhong)方式，一(yi)(yi)種(zhong)是(shi)(shi)氣(qi)嘴(zui)直接伸(shen)到(dao)產(chan)品(pin)袋子里面進行充(chong)(chong)(chong)氣(qi)的(de)(de)(de)，另一(yi)(yi)種(zhong)是(shi)(shi)把要(yao)充(chong)(chong)(chong)的(de)(de)(de)氣(qi)體先充(chong)(chong)(chong)滿整個(ge)真(zhen)空(kong)(kong)(kong)室，然后(hou)靠(kao)負(fu)壓差充(chong)(chong)(chong)滿袋子。那究竟(jing)采(cai)用哪種(zhong)方式充(chong)(chong)(chong)氣(qi)好呢(ni)，這(zhe)里主要(yao)看客(ke)戶的(de)(de)(de)產(chan)品(pin)性質(zhi)，單純來說(shuo)肯定(ding)是(shi)(shi)直接沖到(dao)袋子里比較(jiao)好，這(zhe)樣置換的(de)(de)(de)又(you)純還能(neng)省不(bu)少氣(qi)源，但是(shi)(shi)大家一(yi)(yi)定(ding)要(yao)考慮好自己(ji)產(chan)品(pin)性質(zhi)。如(ru)果(guo)產(chan)品(pin)是(shi)(shi)顆粒，我們可以采(cai)取(qu)起初一(yi)(yi)種(zhong)方法直接讓(rang)充(chong)(chong)(chong)氣(qi)嘴(zui)到(dao)袋子里進行充(chong)(chong)(chong)氣(qi)，但是(shi)(shi)如(ru)果(guo)你的(de)(de)(de)產(chan)品(pin)是(shi)(shi)粉末狀的(de)(de)(de)就(jiu)不(bu)能(neng)用起初一(yi)(yi)種(zhong)方法了，需要(yao)第二種(zhong)在(zai)真(zhen)空(kong)(kong)(kong)室充(chong)(chong)(chong)氣(qi)利用壓力差充(chong)(chong)(chong)滿袋子。可是(shi)(shi)客(ke)戶又(you)要(yao)要(yao)求達到(dao)一(yi)(yi)定(ding)比例(li)的(de)(de)(de)殘氧量，這(zhe)就(jiu)很矛盾(dun)了。
