真空包(bao)裝機廠(chang)的(de)(de)真空包裝機增加充(chong)(chong)(chong)氣(qi)功能是有(you)兩(liang)種(zhong)(zhong)方式，一(yi)種(zhong)(zhong)是氣(qi)嘴(zui)直接伸到(dao)(dao)產(chan)(chan)品袋(dai)子里面進行(xing)(xing)充(chong)(chong)(chong)氣(qi)的(de)(de)，另一(yi)種(zhong)(zhong)是把要(yao)充(chong)(chong)(chong)的(de)(de)氣(qi)體先充(chong)(chong)(chong)滿(man)整個(ge)真空室，然后(hou)靠(kao)負(fu)壓差(cha)充(chong)(chong)(chong)滿(man)袋(dai)子。那究(jiu)竟采用哪種(zhong)(zhong)方式充(chong)(chong)(chong)氣(qi)好(hao)(hao)呢，這(zhe)里主(zhu)要(yao)看(kan)客戶的(de)(de)產(chan)(chan)品性質(zhi)，單純來說肯定(ding)是直接沖到(dao)(dao)袋(dai)子里比較好(hao)(hao)，這(zhe)樣置換的(de)(de)又(you)純還能省不(bu)少氣(qi)源(yuan)，但(dan)是大家一(yi)定(ding)要(yao)考慮好(hao)(hao)自己產(chan)(chan)品性質(zhi)。如(ru)果(guo)產(chan)(chan)品是顆(ke)粒，我們可(ke)以采取起(qi)初一(yi)種(zhong)(zhong)方法(fa)直接讓充(chong)(chong)(chong)氣(qi)嘴(zui)到(dao)(dao)袋(dai)子里進行(xing)(xing)充(chong)(chong)(chong)氣(qi)，但(dan)是如(ru)果(guo)你的(de)(de)產(chan)(chan)品是粉末(mo)狀的(de)(de)就不(bu)能用起(qi)初一(yi)種(zhong)(zhong)方法(fa)了(le)，需要(yao)第(di)二種(zhong)(zhong)在真空室充(chong)(chong)(chong)氣(qi)利用壓力差(cha)充(chong)(chong)(chong)滿(man)袋(dai)子。可(ke)是客戶又(you)要(yao)要(yao)求達到(dao)(dao)一(yi)定(ding)比例(li)的(de)(de)殘氧量，這(zhe)就很矛盾(dun)了(le)。
