真空包(bao)裝機廠(chang)的(de)(de)真空包(bao)裝(zhuang)機增加充(chong)(chong)氣(qi)(qi)功能(neng)是(shi)(shi)有兩種(zhong)(zhong)方式(shi)，一(yi)(yi)種(zhong)(zhong)是(shi)(shi)氣(qi)(qi)嘴直(zhi)接(jie)伸到(dao)(dao)產(chan)品(pin)袋(dai)子(zi)里(li)(li)面(mian)進行充(chong)(chong)氣(qi)(qi)的(de)(de)，另一(yi)(yi)種(zhong)(zhong)是(shi)(shi)把要(yao)充(chong)(chong)的(de)(de)氣(qi)(qi)體(ti)先充(chong)(chong)滿整(zheng)個真空室，然后靠負壓差充(chong)(chong)滿袋(dai)子(zi)。那究竟(jing)采(cai)用哪種(zhong)(zhong)方式(shi)充(chong)(chong)氣(qi)(qi)好(hao)呢，這里(li)(li)主(zhu)要(yao)看客(ke)戶的(de)(de)產(chan)品(pin)性質(zhi)，單純(chun)來說肯(ken)定是(shi)(shi)直(zhi)接(jie)沖到(dao)(dao)袋(dai)子(zi)里(li)(li)比較好(hao)，這樣置換(huan)的(de)(de)又(you)純(chun)還能(neng)省(sheng)不(bu)少氣(qi)(qi)源，但(dan)是(shi)(shi)大家一(yi)(yi)定要(yao)考慮好(hao)自己產(chan)品(pin)性質(zhi)。如(ru)果(guo)產(chan)品(pin)是(shi)(shi)顆粒，我們(men)可以采(cai)取起初一(yi)(yi)種(zhong)(zhong)方法直(zhi)接(jie)讓充(chong)(chong)氣(qi)(qi)嘴到(dao)(dao)袋(dai)子(zi)里(li)(li)進行充(chong)(chong)氣(qi)(qi)，但(dan)是(shi)(shi)如(ru)果(guo)你的(de)(de)產(chan)品(pin)是(shi)(shi)粉(fen)末狀的(de)(de)就不(bu)能(neng)用起初一(yi)(yi)種(zhong)(zhong)方法了，需要(yao)第二(er)種(zhong)(zhong)在真空室充(chong)(chong)氣(qi)(qi)利用壓力(li)差充(chong)(chong)滿袋(dai)子(zi)。可是(shi)(shi)客(ke)戶又(you)要(yao)要(yao)求達(da)到(dao)(dao)一(yi)(yi)定比例(li)的(de)(de)殘氧量，這就很矛盾(dun)了。
