真(zhen)空包裝(zhuang)機廠的真(zhen)空(kong)包裝機增加充(chong)(chong)(chong)氣(qi)功能(neng)是有兩種(zhong)方式(shi)，一(yi)種(zhong)是氣(qi)嘴(zui)直(zhi)接伸(shen)到(dao)產(chan)品(pin)袋(dai)(dai)子里(li)(li)面(mian)進(jin)行充(chong)(chong)(chong)氣(qi)的，另(ling)一(yi)種(zhong)是把要(yao)充(chong)(chong)(chong)的氣(qi)體先(xian)充(chong)(chong)(chong)滿(man)整(zheng)個(ge)真(zhen)空(kong)室(shi)，然后靠負壓差充(chong)(chong)(chong)滿(man)袋(dai)(dai)子。那究竟采用哪種(zhong)方式(shi)充(chong)(chong)(chong)氣(qi)好呢，這(zhe)里(li)(li)主(zhu)要(yao)看(kan)客戶的產(chan)品(pin)性質(zhi)，單(dan)純(chun)來說肯(ken)定(ding)(ding)是直(zhi)接沖到(dao)袋(dai)(dai)子里(li)(li)比較好，這(zhe)樣置換的又(you)純(chun)還(huan)能(neng)省(sheng)不少(shao)氣(qi)源，但是大(da)家一(yi)定(ding)(ding)要(yao)考慮好自己產(chan)品(pin)性質(zhi)。如(ru)果(guo)產(chan)品(pin)是顆粒，我們可以采取起初一(yi)種(zhong)方法(fa)直(zhi)接讓充(chong)(chong)(chong)氣(qi)嘴(zui)到(dao)袋(dai)(dai)子里(li)(li)進(jin)行充(chong)(chong)(chong)氣(qi)，但是如(ru)果(guo)你的產(chan)品(pin)是粉末(mo)狀的就(jiu)不能(neng)用起初一(yi)種(zhong)方法(fa)了，需要(yao)第二(er)種(zhong)在真(zhen)空(kong)室(shi)充(chong)(chong)(chong)氣(qi)利(li)用壓力(li)差充(chong)(chong)(chong)滿(man)袋(dai)(dai)子。可是客戶又(you)要(yao)要(yao)求達(da)到(dao)一(yi)定(ding)(ding)比例(li)的殘氧量，這(zhe)就(jiu)很矛盾了。
