真空包(bao)裝(zhuang)機廠的(de)真(zhen)空包裝機增加充(chong)(chong)(chong)(chong)(chong)氣(qi)(qi)(qi)功能(neng)(neng)是(shi)(shi)有兩種(zhong)方式(shi)，一種(zhong)是(shi)(shi)氣(qi)(qi)(qi)嘴(zui)直(zhi)接(jie)伸到(dao)(dao)產(chan)品袋(dai)(dai)子里面進(jin)行(xing)充(chong)(chong)(chong)(chong)(chong)氣(qi)(qi)(qi)的(de)，另(ling)一種(zhong)是(shi)(shi)把要(yao)(yao)充(chong)(chong)(chong)(chong)(chong)的(de)氣(qi)(qi)(qi)體先(xian)充(chong)(chong)(chong)(chong)(chong)滿整個真(zhen)空室，然(ran)后靠負壓差(cha)充(chong)(chong)(chong)(chong)(chong)滿袋(dai)(dai)子。那究竟采用哪種(zhong)方式(shi)充(chong)(chong)(chong)(chong)(chong)氣(qi)(qi)(qi)好呢，這里主要(yao)(yao)看客(ke)戶(hu)的(de)產(chan)品性質，單純來說肯定(ding)是(shi)(shi)直(zhi)接(jie)沖到(dao)(dao)袋(dai)(dai)子里比較好，這樣(yang)置(zhi)換(huan)的(de)又純還能(neng)(neng)省不(bu)少(shao)氣(qi)(qi)(qi)源，但(dan)是(shi)(shi)大家一定(ding)要(yao)(yao)考慮好自己產(chan)品性質。如(ru)果產(chan)品是(shi)(shi)顆粒，我們可以采取起初(chu)一種(zhong)方法(fa)直(zhi)接(jie)讓充(chong)(chong)(chong)(chong)(chong)氣(qi)(qi)(qi)嘴(zui)到(dao)(dao)袋(dai)(dai)子里進(jin)行(xing)充(chong)(chong)(chong)(chong)(chong)氣(qi)(qi)(qi)，但(dan)是(shi)(shi)如(ru)果你(ni)的(de)產(chan)品是(shi)(shi)粉(fen)末(mo)狀的(de)就不(bu)能(neng)(neng)用起初(chu)一種(zhong)方法(fa)了(le)，需要(yao)(yao)第二(er)種(zhong)在真(zhen)空室充(chong)(chong)(chong)(chong)(chong)氣(qi)(qi)(qi)利(li)用壓力差(cha)充(chong)(chong)(chong)(chong)(chong)滿袋(dai)(dai)子。可是(shi)(shi)客(ke)戶(hu)又要(yao)(yao)要(yao)(yao)求達到(dao)(dao)一定(ding)比例的(de)殘氧量(liang)，這就很矛盾了(le)。
