真空(kong)包裝機廠的(de)(de)(de)真(zhen)空包裝(zhuang)機(ji)增加充(chong)(chong)(chong)氣(qi)(qi)功能(neng)是(shi)有(you)兩種(zhong)方(fang)式(shi)，一(yi)種(zhong)是(shi)氣(qi)(qi)嘴直(zhi)接(jie)伸到(dao)產(chan)品(pin)袋子(zi)(zi)里面進行充(chong)(chong)(chong)氣(qi)(qi)的(de)(de)(de)，另一(yi)種(zhong)是(shi)把要(yao)充(chong)(chong)(chong)的(de)(de)(de)氣(qi)(qi)體先充(chong)(chong)(chong)滿整個真(zhen)空室，然后靠負壓差充(chong)(chong)(chong)滿袋子(zi)(zi)。那(nei)究竟采(cai)用(yong)哪種(zhong)方(fang)式(shi)充(chong)(chong)(chong)氣(qi)(qi)好呢，這里主要(yao)看客戶(hu)的(de)(de)(de)產(chan)品(pin)性質，單純來(lai)說肯定是(shi)直(zhi)接(jie)沖到(dao)袋子(zi)(zi)里比較(jiao)好，這樣置換的(de)(de)(de)又純還能(neng)省不(bu)少氣(qi)(qi)源(yuan)，但是(shi)大家(jia)一(yi)定要(yao)考慮(lv)好自己產(chan)品(pin)性質。如(ru)果產(chan)品(pin)是(shi)顆粒，我們(men)可(ke)(ke)以(yi)采(cai)取起(qi)初一(yi)種(zhong)方(fang)法直(zhi)接(jie)讓充(chong)(chong)(chong)氣(qi)(qi)嘴到(dao)袋子(zi)(zi)里進行充(chong)(chong)(chong)氣(qi)(qi)，但是(shi)如(ru)果你的(de)(de)(de)產(chan)品(pin)是(shi)粉末狀的(de)(de)(de)就(jiu)不(bu)能(neng)用(yong)起(qi)初一(yi)種(zhong)方(fang)法了，需要(yao)第二種(zhong)在真(zhen)空室充(chong)(chong)(chong)氣(qi)(qi)利用(yong)壓力差充(chong)(chong)(chong)滿袋子(zi)(zi)。可(ke)(ke)是(shi)客戶(hu)又要(yao)要(yao)求(qiu)達到(dao)一(yi)定比例的(de)(de)(de)殘氧量，這就(jiu)很(hen)矛盾(dun)了。
