真空包裝機廠的(de)(de)真(zhen)空包(bao)裝機增加充(chong)(chong)氣(qi)功能是(shi)(shi)(shi)有兩種(zhong)方(fang)式，一(yi)(yi)種(zhong)是(shi)(shi)(shi)氣(qi)嘴(zui)直(zhi)接(jie)伸到(dao)產(chan)(chan)品袋子里(li)面(mian)進(jin)行充(chong)(chong)氣(qi)的(de)(de)，另一(yi)(yi)種(zhong)是(shi)(shi)(shi)把要充(chong)(chong)的(de)(de)氣(qi)體先充(chong)(chong)滿(man)整個(ge)真(zhen)空室(shi)，然后靠(kao)負壓差充(chong)(chong)滿(man)袋子。那究竟采(cai)用哪種(zhong)方(fang)式充(chong)(chong)氣(qi)好呢，這里(li)主要看客戶的(de)(de)產(chan)(chan)品性(xing)質(zhi)，單純(chun)來說肯定(ding)是(shi)(shi)(shi)直(zhi)接(jie)沖(chong)到(dao)袋子里(li)比較好，這樣置換的(de)(de)又純(chun)還能省(sheng)不少氣(qi)源，但是(shi)(shi)(shi)大家一(yi)(yi)定(ding)要考慮好自己產(chan)(chan)品性(xing)質(zhi)。如(ru)果產(chan)(chan)品是(shi)(shi)(shi)顆粒，我們(men)可(ke)(ke)以(yi)采(cai)取起初一(yi)(yi)種(zhong)方(fang)法直(zhi)接(jie)讓充(chong)(chong)氣(qi)嘴(zui)到(dao)袋子里(li)進(jin)行充(chong)(chong)氣(qi)，但是(shi)(shi)(shi)如(ru)果你的(de)(de)產(chan)(chan)品是(shi)(shi)(shi)粉末狀的(de)(de)就(jiu)(jiu)不能用起初一(yi)(yi)種(zhong)方(fang)法了，需要第二種(zhong)在真(zhen)空室(shi)充(chong)(chong)氣(qi)利用壓力差充(chong)(chong)滿(man)袋子。可(ke)(ke)是(shi)(shi)(shi)客戶又要要求達到(dao)一(yi)(yi)定(ding)比例的(de)(de)殘氧(yang)量，這就(jiu)(jiu)很矛盾了。
