真空包裝機廠的(de)(de)(de)真(zhen)空(kong)包裝機增加(jia)充(chong)(chong)氣功(gong)能是(shi)有(you)兩(liang)種(zhong)(zhong)(zhong)方(fang)式，一種(zhong)(zhong)(zhong)是(shi)氣嘴直接伸到產(chan)品(pin)袋(dai)(dai)子里(li)(li)面(mian)進行(xing)充(chong)(chong)氣的(de)(de)(de)，另(ling)一種(zhong)(zhong)(zhong)是(shi)把要充(chong)(chong)的(de)(de)(de)氣體先充(chong)(chong)滿整個真(zhen)空(kong)室，然后靠負壓差充(chong)(chong)滿袋(dai)(dai)子。那究竟采用(yong)哪種(zhong)(zhong)(zhong)方(fang)式充(chong)(chong)氣好(hao)呢，這(zhe)里(li)(li)主要看客戶(hu)的(de)(de)(de)產(chan)品(pin)性(xing)質(zhi)，單純來說肯定是(shi)直接沖到袋(dai)(dai)子里(li)(li)比較好(hao)，這(zhe)樣置換(huan)的(de)(de)(de)又(you)(you)純還能省不少氣源，但(dan)是(shi)大家一定要考慮好(hao)自己產(chan)品(pin)性(xing)質(zhi)。如(ru)果產(chan)品(pin)是(shi)顆(ke)粒，我們(men)可(ke)以采取起初一種(zhong)(zhong)(zhong)方(fang)法直接讓(rang)充(chong)(chong)氣嘴到袋(dai)(dai)子里(li)(li)進行(xing)充(chong)(chong)氣，但(dan)是(shi)如(ru)果你的(de)(de)(de)產(chan)品(pin)是(shi)粉末狀的(de)(de)(de)就不能用(yong)起初一種(zhong)(zhong)(zhong)方(fang)法了，需要第二種(zhong)(zhong)(zhong)在真(zhen)空(kong)室充(chong)(chong)氣利(li)用(yong)壓力(li)差充(chong)(chong)滿袋(dai)(dai)子。可(ke)是(shi)客戶(hu)又(you)(you)要要求(qiu)達(da)到一定比例(li)的(de)(de)(de)殘氧量，這(zhe)就很(hen)矛盾(dun)了。
