真空包裝(zhuang)機廠(chang)的(de)(de)(de)真(zhen)空包(bao)裝機增加(jia)充(chong)(chong)(chong)氣(qi)(qi)(qi)功能是(shi)(shi)有兩種方(fang)式，一(yi)種是(shi)(shi)氣(qi)(qi)(qi)嘴直接伸(shen)到產(chan)(chan)(chan)品(pin)袋(dai)子(zi)里(li)面(mian)進行充(chong)(chong)(chong)氣(qi)(qi)(qi)的(de)(de)(de)，另(ling)一(yi)種是(shi)(shi)把要(yao)充(chong)(chong)(chong)的(de)(de)(de)氣(qi)(qi)(qi)體(ti)先充(chong)(chong)(chong)滿(man)整(zheng)個真(zhen)空室(shi)，然后靠(kao)負(fu)壓(ya)差充(chong)(chong)(chong)滿(man)袋(dai)子(zi)。那究竟采(cai)用哪種方(fang)式充(chong)(chong)(chong)氣(qi)(qi)(qi)好呢，這里(li)主要(yao)看客(ke)戶(hu)的(de)(de)(de)產(chan)(chan)(chan)品(pin)性(xing)質，單純來說肯定(ding)是(shi)(shi)直接沖到袋(dai)子(zi)里(li)比(bi)較好，這樣置換的(de)(de)(de)又純還能省不少氣(qi)(qi)(qi)源(yuan)，但是(shi)(shi)大家一(yi)定(ding)要(yao)考慮好自己產(chan)(chan)(chan)品(pin)性(xing)質。如(ru)果產(chan)(chan)(chan)品(pin)是(shi)(shi)顆(ke)粒，我們可(ke)以采(cai)取起(qi)初一(yi)種方(fang)法直接讓充(chong)(chong)(chong)氣(qi)(qi)(qi)嘴到袋(dai)子(zi)里(li)進行充(chong)(chong)(chong)氣(qi)(qi)(qi)，但是(shi)(shi)如(ru)果你的(de)(de)(de)產(chan)(chan)(chan)品(pin)是(shi)(shi)粉末狀的(de)(de)(de)就不能用起(qi)初一(yi)種方(fang)法了，需要(yao)第二種在真(zhen)空室(shi)充(chong)(chong)(chong)氣(qi)(qi)(qi)利用壓(ya)力(li)差充(chong)(chong)(chong)滿(man)袋(dai)子(zi)。可(ke)是(shi)(shi)客(ke)戶(hu)又要(yao)要(yao)求達到一(yi)定(ding)比(bi)例的(de)(de)(de)殘氧量，這就很矛盾了。
