真空包裝(zhuang)機廠的(de)(de)真(zhen)空包裝機增加(jia)充(chong)(chong)氣(qi)(qi)(qi)功能(neng)(neng)是(shi)(shi)(shi)有兩種(zhong)方式(shi)，一種(zhong)是(shi)(shi)(shi)氣(qi)(qi)(qi)嘴直(zhi)(zhi)接伸到(dao)產(chan)品袋(dai)(dai)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(yao)(yao)(yao)充(chong)(chong)的(de)(de)氣(qi)(qi)(qi)體先充(chong)(chong)滿(man)整個真(zhen)空室(shi)，然(ran)后(hou)靠負壓差充(chong)(chong)滿(man)袋(dai)(dai)子(zi)。那究竟采(cai)用哪(na)種(zhong)方式(shi)充(chong)(chong)氣(qi)(qi)(qi)好(hao)呢，這里(li)主要(yao)(yao)(yao)看(kan)客戶的(de)(de)產(chan)品性(xing)質(zhi)，單(dan)純(chun)來(lai)說(shuo)肯定(ding)是(shi)(shi)(shi)直(zhi)(zhi)接沖到(dao)袋(dai)(dai)子(zi)里(li)比較好(hao)，這樣置換的(de)(de)又純(chun)還能(neng)(neng)省不少氣(qi)(qi)(qi)源，但(dan)是(shi)(shi)(shi)大家一定(ding)要(yao)(yao)(yao)考慮(lv)好(hao)自己產(chan)品性(xing)質(zhi)。如(ru)果產(chan)品是(shi)(shi)(shi)顆粒，我(wo)們可以采(cai)取起初(chu)一種(zhong)方法直(zhi)(zhi)接讓充(chong)(chong)氣(qi)(qi)(qi)嘴到(dao)袋(dai)(dai)子(zi)里(li)進行充(chong)(chong)氣(qi)(qi)(qi)，但(dan)是(shi)(shi)(shi)如(ru)果你的(de)(de)產(chan)品是(shi)(shi)(shi)粉末狀(zhuang)的(de)(de)就不能(neng)(neng)用起初(chu)一種(zhong)方法了，需要(yao)(yao)(yao)第二種(zhong)在真(zhen)空室(shi)充(chong)(chong)氣(qi)(qi)(qi)利用壓力差充(chong)(chong)滿(man)袋(dai)(dai)子(zi)。可是(shi)(shi)(shi)客戶又要(yao)(yao)(yao)要(yao)(yao)(yao)求達(da)到(dao)一定(ding)比例(li)的(de)(de)殘氧(yang)量，這就很矛盾了。
