真空包裝(zhuang)機廠的(de)(de)(de)真(zhen)空(kong)(kong)包裝機(ji)增加充(chong)(chong)氣(qi)功能(neng)是(shi)(shi)有兩(liang)種(zhong)(zhong)方式(shi)，一(yi)(yi)種(zhong)(zhong)是(shi)(shi)氣(qi)嘴直(zhi)接伸到(dao)產品袋子里面(mian)進行(xing)充(chong)(chong)氣(qi)的(de)(de)(de)，另一(yi)(yi)種(zhong)(zhong)是(shi)(shi)把要充(chong)(chong)的(de)(de)(de)氣(qi)體先(xian)充(chong)(chong)滿(man)整(zheng)個真(zhen)空(kong)(kong)室(shi)(shi)，然后靠負壓差充(chong)(chong)滿(man)袋子。那究竟(jing)采(cai)用(yong)(yong)哪(na)種(zhong)(zhong)方式(shi)充(chong)(chong)氣(qi)好(hao)(hao)呢(ni)，這里主要看客戶(hu)的(de)(de)(de)產品性(xing)質(zhi)，單(dan)純(chun)來說(shuo)肯定是(shi)(shi)直(zhi)接沖到(dao)袋子里比較(jiao)好(hao)(hao)，這樣(yang)置(zhi)換的(de)(de)(de)又純(chun)還能(neng)省不(bu)少(shao)氣(qi)源，但是(shi)(shi)大家一(yi)(yi)定要考慮好(hao)(hao)自己產品性(xing)質(zhi)。如(ru)果(guo)產品是(shi)(shi)顆粒，我們可(ke)以采(cai)取(qu)起初(chu)一(yi)(yi)種(zhong)(zhong)方法(fa)直(zhi)接讓充(chong)(chong)氣(qi)嘴到(dao)袋子里進行(xing)充(chong)(chong)氣(qi)，但是(shi)(shi)如(ru)果(guo)你(ni)的(de)(de)(de)產品是(shi)(shi)粉末狀的(de)(de)(de)就(jiu)不(bu)能(neng)用(yong)(yong)起初(chu)一(yi)(yi)種(zhong)(zhong)方法(fa)了(le)，需要第(di)二(er)種(zhong)(zhong)在(zai)真(zhen)空(kong)(kong)室(shi)(shi)充(chong)(chong)氣(qi)利用(yong)(yong)壓力差充(chong)(chong)滿(man)袋子。可(ke)是(shi)(shi)客戶(hu)又要要求達到(dao)一(yi)(yi)定比例的(de)(de)(de)殘氧量，這就(jiu)很矛盾了(le)。
