真空(kong)包裝機(ji)廠(chang)的(de)真(zhen)空包裝機增加充(chong)(chong)氣(qi)(qi)功能是(shi)(shi)有兩種方(fang)(fang)(fang)式(shi)，一(yi)種是(shi)(shi)氣(qi)(qi)嘴直接伸到產品(pin)袋子(zi)里(li)(li)面進行(xing)充(chong)(chong)氣(qi)(qi)的(de)，另一(yi)種是(shi)(shi)把(ba)要(yao)(yao)(yao)充(chong)(chong)的(de)氣(qi)(qi)體(ti)先(xian)充(chong)(chong)滿整個真(zhen)空室，然后靠負(fu)壓差(cha)充(chong)(chong)滿袋子(zi)。那(nei)究竟(jing)采用(yong)(yong)哪種方(fang)(fang)(fang)式(shi)充(chong)(chong)氣(qi)(qi)好呢，這(zhe)里(li)(li)主要(yao)(yao)(yao)看(kan)客(ke)(ke)戶的(de)產品(pin)性質(zhi)，單純(chun)來說肯定(ding)是(shi)(shi)直接沖到袋子(zi)里(li)(li)比較(jiao)好，這(zhe)樣置換的(de)又(you)純(chun)還能省(sheng)不(bu)少氣(qi)(qi)源(yuan)，但(dan)是(shi)(shi)大家一(yi)定(ding)要(yao)(yao)(yao)考慮好自己(ji)產品(pin)性質(zhi)。如果產品(pin)是(shi)(shi)顆粒，我們(men)可(ke)(ke)以采取起(qi)初一(yi)種方(fang)(fang)(fang)法直接讓充(chong)(chong)氣(qi)(qi)嘴到袋子(zi)里(li)(li)進行(xing)充(chong)(chong)氣(qi)(qi)，但(dan)是(shi)(shi)如果你的(de)產品(pin)是(shi)(shi)粉末狀的(de)就(jiu)不(bu)能用(yong)(yong)起(qi)初一(yi)種方(fang)(fang)(fang)法了，需要(yao)(yao)(yao)第二(er)種在真(zhen)空室充(chong)(chong)氣(qi)(qi)利用(yong)(yong)壓力(li)差(cha)充(chong)(chong)滿袋子(zi)。可(ke)(ke)是(shi)(shi)客(ke)(ke)戶又(you)要(yao)(yao)(yao)要(yao)(yao)(yao)求達到一(yi)定(ding)比例(li)的(de)殘氧量，這(zhe)就(jiu)很矛(mao)盾(dun)了。
