真空包裝機廠的(de)(de)真(zhen)空包裝機增加(jia)充(chong)(chong)(chong)氣(qi)(qi)功能(neng)是(shi)(shi)有兩種方式(shi)，一(yi)種是(shi)(shi)氣(qi)(qi)嘴直接伸到產品(pin)袋(dai)子里面進行(xing)充(chong)(chong)(chong)氣(qi)(qi)的(de)(de)，另一(yi)種是(shi)(shi)把要(yao)(yao)充(chong)(chong)(chong)的(de)(de)氣(qi)(qi)體先充(chong)(chong)(chong)滿(man)整個真(zhen)空室，然后(hou)靠負(fu)壓差充(chong)(chong)(chong)滿(man)袋(dai)子。那究竟(jing)采用(yong)哪種方式(shi)充(chong)(chong)(chong)氣(qi)(qi)好呢(ni)，這里主要(yao)(yao)看客戶(hu)的(de)(de)產品(pin)性(xing)質，單(dan)純來說肯定(ding)是(shi)(shi)直接沖到袋(dai)子里比較好，這樣(yang)置換的(de)(de)又(you)純還能(neng)省不少氣(qi)(qi)源，但是(shi)(shi)大(da)家一(yi)定(ding)要(yao)(yao)考慮(lv)好自己產品(pin)性(xing)質。如(ru)(ru)果產品(pin)是(shi)(shi)顆粒，我們可(ke)以采取起初一(yi)種方法(fa)直接讓充(chong)(chong)(chong)氣(qi)(qi)嘴到袋(dai)子里進行(xing)充(chong)(chong)(chong)氣(qi)(qi)，但是(shi)(shi)如(ru)(ru)果你的(de)(de)產品(pin)是(shi)(shi)粉末狀的(de)(de)就不能(neng)用(yong)起初一(yi)種方法(fa)了，需要(yao)(yao)第二(er)種在真(zhen)空室充(chong)(chong)(chong)氣(qi)(qi)利用(yong)壓力差充(chong)(chong)(chong)滿(man)袋(dai)子。可(ke)是(shi)(shi)客戶(hu)又(you)要(yao)(yao)要(yao)(yao)求(qiu)達到一(yi)定(ding)比例的(de)(de)殘(can)氧量(liang)，這就很矛盾了。
