真空包裝機廠的(de)(de)真空(kong)包裝機增加充(chong)(chong)(chong)(chong)(chong)氣(qi)(qi)(qi)功(gong)能是(shi)(shi)有兩種(zhong)方式，一種(zhong)是(shi)(shi)氣(qi)(qi)(qi)嘴直(zhi)接伸到產(chan)品袋子里(li)面(mian)進(jin)行充(chong)(chong)(chong)(chong)(chong)氣(qi)(qi)(qi)的(de)(de)，另一種(zhong)是(shi)(shi)把要(yao)(yao)充(chong)(chong)(chong)(chong)(chong)的(de)(de)氣(qi)(qi)(qi)體先充(chong)(chong)(chong)(chong)(chong)滿(man)整個真空(kong)室，然后靠負壓差充(chong)(chong)(chong)(chong)(chong)滿(man)袋子。那究(jiu)竟采(cai)用(yong)哪種(zhong)方式充(chong)(chong)(chong)(chong)(chong)氣(qi)(qi)(qi)好(hao)呢，這(zhe)(zhe)里(li)主要(yao)(yao)看(kan)客戶的(de)(de)產(chan)品性質，單純(chun)來(lai)說肯(ken)定(ding)是(shi)(shi)直(zhi)接沖到袋子里(li)比(bi)較好(hao)，這(zhe)(zhe)樣(yang)置(zhi)換的(de)(de)又純(chun)還能省不(bu)少(shao)氣(qi)(qi)(qi)源(yuan)，但是(shi)(shi)大(da)家一定(ding)要(yao)(yao)考慮(lv)好(hao)自己產(chan)品性質。如果(guo)產(chan)品是(shi)(shi)顆粒，我們可以采(cai)取(qu)起初(chu)一種(zhong)方法直(zhi)接讓(rang)充(chong)(chong)(chong)(chong)(chong)氣(qi)(qi)(qi)嘴到袋子里(li)進(jin)行充(chong)(chong)(chong)(chong)(chong)氣(qi)(qi)(qi)，但是(shi)(shi)如果(guo)你的(de)(de)產(chan)品是(shi)(shi)粉末狀的(de)(de)就(jiu)不(bu)能用(yong)起初(chu)一種(zhong)方法了，需要(yao)(yao)第(di)二種(zhong)在真空(kong)室充(chong)(chong)(chong)(chong)(chong)氣(qi)(qi)(qi)利(li)用(yong)壓力差充(chong)(chong)(chong)(chong)(chong)滿(man)袋子。可是(shi)(shi)客戶又要(yao)(yao)要(yao)(yao)求達(da)到一定(ding)比(bi)例(li)的(de)(de)殘氧量，這(zhe)(zhe)就(jiu)很矛盾了。
