真空包裝機(ji)廠的(de)(de)真空(kong)包裝機增加充(chong)氣(qi)(qi)(qi)功能是(shi)(shi)有(you)兩種(zhong)(zhong)方式，一(yi)種(zhong)(zhong)是(shi)(shi)氣(qi)(qi)(qi)嘴(zui)直接伸到(dao)產(chan)品(pin)袋子(zi)里(li)(li)面進(jin)行(xing)(xing)充(chong)氣(qi)(qi)(qi)的(de)(de)，另一(yi)種(zhong)(zhong)是(shi)(shi)把(ba)要(yao)(yao)充(chong)的(de)(de)氣(qi)(qi)(qi)體先充(chong)滿整個真空(kong)室，然(ran)后靠負壓差充(chong)滿袋子(zi)。那究(jiu)竟采(cai)用哪種(zhong)(zhong)方式充(chong)氣(qi)(qi)(qi)好(hao)呢，這(zhe)里(li)(li)主要(yao)(yao)看客(ke)戶的(de)(de)產(chan)品(pin)性質(zhi)，單(dan)純來說肯(ken)定(ding)是(shi)(shi)直接沖到(dao)袋子(zi)里(li)(li)比(bi)較好(hao)，這(zhe)樣置換的(de)(de)又純還能省(sheng)不少氣(qi)(qi)(qi)源，但是(shi)(shi)大家一(yi)定(ding)要(yao)(yao)考慮(lv)好(hao)自(zi)己(ji)產(chan)品(pin)性質(zhi)。如(ru)(ru)果產(chan)品(pin)是(shi)(shi)顆粒，我們可以采(cai)取起初一(yi)種(zhong)(zhong)方法直接讓充(chong)氣(qi)(qi)(qi)嘴(zui)到(dao)袋子(zi)里(li)(li)進(jin)行(xing)(xing)充(chong)氣(qi)(qi)(qi)，但是(shi)(shi)如(ru)(ru)果你的(de)(de)產(chan)品(pin)是(shi)(shi)粉末狀的(de)(de)就不能用起初一(yi)種(zhong)(zhong)方法了，需要(yao)(yao)第二(er)種(zhong)(zhong)在真空(kong)室充(chong)氣(qi)(qi)(qi)利用壓力差充(chong)滿袋子(zi)。可是(shi)(shi)客(ke)戶又要(yao)(yao)要(yao)(yao)求達到(dao)一(yi)定(ding)比(bi)例的(de)(de)殘(can)氧量，這(zhe)就很矛盾了。
