真空包裝機廠的(de)真(zhen)空包(bao)裝機(ji)增加充(chong)(chong)(chong)氣(qi)(qi)功能是(shi)(shi)有(you)兩(liang)種(zhong)方(fang)式，一(yi)(yi)種(zhong)是(shi)(shi)氣(qi)(qi)嘴直接伸到(dao)產(chan)(chan)品袋(dai)子里(li)面進(jin)行充(chong)(chong)(chong)氣(qi)(qi)的(de)，另一(yi)(yi)種(zhong)是(shi)(shi)把(ba)要(yao)充(chong)(chong)(chong)的(de)氣(qi)(qi)體先充(chong)(chong)(chong)滿(man)整個真(zhen)空室，然后靠負壓差(cha)充(chong)(chong)(chong)滿(man)袋(dai)子。那究竟采(cai)(cai)用(yong)(yong)哪(na)種(zhong)方(fang)式充(chong)(chong)(chong)氣(qi)(qi)好(hao)呢，這里(li)主要(yao)看客(ke)戶(hu)的(de)產(chan)(chan)品性質，單純(chun)來說肯定(ding)是(shi)(shi)直接沖到(dao)袋(dai)子里(li)比較好(hao)，這樣置換的(de)又(you)(you)純(chun)還(huan)能省不少(shao)氣(qi)(qi)源，但(dan)是(shi)(shi)大家一(yi)(yi)定(ding)要(yao)考慮好(hao)自(zi)己產(chan)(chan)品性質。如果(guo)產(chan)(chan)品是(shi)(shi)顆粒，我們可(ke)以采(cai)(cai)取(qu)起初(chu)一(yi)(yi)種(zhong)方(fang)法直接讓充(chong)(chong)(chong)氣(qi)(qi)嘴到(dao)袋(dai)子里(li)進(jin)行充(chong)(chong)(chong)氣(qi)(qi)，但(dan)是(shi)(shi)如果(guo)你(ni)的(de)產(chan)(chan)品是(shi)(shi)粉(fen)末(mo)狀的(de)就不能用(yong)(yong)起初(chu)一(yi)(yi)種(zhong)方(fang)法了(le)，需要(yao)第二種(zhong)在真(zhen)空室充(chong)(chong)(chong)氣(qi)(qi)利用(yong)(yong)壓力差(cha)充(chong)(chong)(chong)滿(man)袋(dai)子。可(ke)是(shi)(shi)客(ke)戶(hu)又(you)(you)要(yao)要(yao)求(qiu)達到(dao)一(yi)(yi)定(ding)比例(li)的(de)殘氧(yang)量，這就很(hen)矛盾了(le)。
