真空(kong)包裝機廠(chang)的(de)真(zhen)空包(bao)裝機增加(jia)充(chong)(chong)氣(qi)功能(neng)是(shi)(shi)(shi)有兩(liang)種(zhong)(zhong)方(fang)式(shi)，一(yi)種(zhong)(zhong)是(shi)(shi)(shi)氣(qi)嘴直(zhi)(zhi)接伸到產品(pin)袋(dai)子里面進(jin)行充(chong)(chong)氣(qi)的(de)，另一(yi)種(zhong)(zhong)是(shi)(shi)(shi)把(ba)要(yao)(yao)充(chong)(chong)的(de)氣(qi)體先充(chong)(chong)滿整個真(zhen)空室(shi)，然后靠負(fu)壓差充(chong)(chong)滿袋(dai)子。那究竟采用哪種(zhong)(zhong)方(fang)式(shi)充(chong)(chong)氣(qi)好(hao)呢，這(zhe)里主要(yao)(yao)看(kan)客戶的(de)產品(pin)性質，單純來說肯定(ding)是(shi)(shi)(shi)直(zhi)(zhi)接沖(chong)到袋(dai)子里比(bi)較(jiao)好(hao)，這(zhe)樣置換的(de)又純還能(neng)省不(bu)少氣(qi)源，但(dan)是(shi)(shi)(shi)大(da)家一(yi)定(ding)要(yao)(yao)考慮好(hao)自己產品(pin)性質。如果(guo)產品(pin)是(shi)(shi)(shi)顆粒，我們可(ke)以采取起初一(yi)種(zhong)(zhong)方(fang)法(fa)(fa)直(zhi)(zhi)接讓充(chong)(chong)氣(qi)嘴到袋(dai)子里進(jin)行充(chong)(chong)氣(qi)，但(dan)是(shi)(shi)(shi)如果(guo)你的(de)產品(pin)是(shi)(shi)(shi)粉末(mo)狀(zhuang)的(de)就不(bu)能(neng)用起初一(yi)種(zhong)(zhong)方(fang)法(fa)(fa)了(le)(le)，需要(yao)(yao)第(di)二種(zhong)(zhong)在真(zhen)空室(shi)充(chong)(chong)氣(qi)利用壓力差充(chong)(chong)滿袋(dai)子。可(ke)是(shi)(shi)(shi)客戶又要(yao)(yao)要(yao)(yao)求達到一(yi)定(ding)比(bi)例的(de)殘氧量，這(zhe)就很矛盾(dun)了(le)(le)。
