真空包裝機廠(chang)的(de)(de)真(zhen)空包裝(zhuang)機增加充(chong)(chong)氣(qi)(qi)(qi)功(gong)能(neng)(neng)是(shi)(shi)(shi)有兩(liang)種(zhong)方(fang)式，一種(zhong)是(shi)(shi)(shi)氣(qi)(qi)(qi)嘴(zui)直(zhi)(zhi)接伸到(dao)產(chan)品袋子(zi)里(li)面進行充(chong)(chong)氣(qi)(qi)(qi)的(de)(de)，另一種(zhong)是(shi)(shi)(shi)把要充(chong)(chong)的(de)(de)氣(qi)(qi)(qi)體(ti)先充(chong)(chong)滿(man)(man)整(zheng)個真(zhen)空室，然后靠(kao)負壓(ya)差(cha)充(chong)(chong)滿(man)(man)袋子(zi)。那(nei)究竟采用哪種(zhong)方(fang)式充(chong)(chong)氣(qi)(qi)(qi)好呢，這(zhe)里(li)主要看(kan)客戶的(de)(de)產(chan)品性(xing)質(zhi)，單(dan)純來說肯定(ding)是(shi)(shi)(shi)直(zhi)(zhi)接沖到(dao)袋子(zi)里(li)比較好，這(zhe)樣(yang)置換的(de)(de)又(you)純還能(neng)(neng)省不(bu)少氣(qi)(qi)(qi)源(yuan)，但(dan)是(shi)(shi)(shi)大家一定(ding)要考(kao)慮好自己產(chan)品性(xing)質(zhi)。如(ru)果(guo)產(chan)品是(shi)(shi)(shi)顆粒，我(wo)們(men)可以采取起(qi)初(chu)(chu)一種(zhong)方(fang)法直(zhi)(zhi)接讓充(chong)(chong)氣(qi)(qi)(qi)嘴(zui)到(dao)袋子(zi)里(li)進行充(chong)(chong)氣(qi)(qi)(qi)，但(dan)是(shi)(shi)(shi)如(ru)果(guo)你的(de)(de)產(chan)品是(shi)(shi)(shi)粉末狀的(de)(de)就不(bu)能(neng)(neng)用起(qi)初(chu)(chu)一種(zhong)方(fang)法了，需要第二(er)種(zhong)在真(zhen)空室充(chong)(chong)氣(qi)(qi)(qi)利用壓(ya)力差(cha)充(chong)(chong)滿(man)(man)袋子(zi)。可是(shi)(shi)(shi)客戶又(you)要要求(qiu)達到(dao)一定(ding)比例的(de)(de)殘氧量(liang)，這(zhe)就很矛(mao)盾了。
