真空包裝機廠的(de)真空(kong)包裝機(ji)增(zeng)加(jia)充(chong)氣(qi)(qi)功能是(shi)(shi)有兩種(zhong)(zhong)(zhong)方式，一(yi)種(zhong)(zhong)(zhong)是(shi)(shi)氣(qi)(qi)嘴直(zhi)接伸到(dao)(dao)產(chan)(chan)品(pin)袋子里(li)(li)(li)面(mian)進(jin)(jin)行(xing)充(chong)氣(qi)(qi)的(de)，另一(yi)種(zhong)(zhong)(zhong)是(shi)(shi)把要(yao)(yao)(yao)(yao)充(chong)的(de)氣(qi)(qi)體先充(chong)滿整個真空(kong)室(shi)，然后(hou)靠(kao)負壓(ya)(ya)差(cha)(cha)充(chong)滿袋子。那究竟采(cai)用(yong)哪(na)種(zhong)(zhong)(zhong)方式充(chong)氣(qi)(qi)好(hao)呢，這(zhe)里(li)(li)(li)主要(yao)(yao)(yao)(yao)看客(ke)戶(hu)的(de)產(chan)(chan)品(pin)性(xing)質，單(dan)純來說肯定是(shi)(shi)直(zhi)接沖到(dao)(dao)袋子里(li)(li)(li)比較(jiao)好(hao)，這(zhe)樣置換的(de)又(you)(you)純還能省不(bu)少氣(qi)(qi)源(yuan)，但(dan)是(shi)(shi)大家一(yi)定要(yao)(yao)(yao)(yao)考慮好(hao)自己產(chan)(chan)品(pin)性(xing)質。如(ru)果產(chan)(chan)品(pin)是(shi)(shi)顆粒(li)，我們可(ke)以采(cai)取起(qi)初一(yi)種(zhong)(zhong)(zhong)方法直(zhi)接讓充(chong)氣(qi)(qi)嘴到(dao)(dao)袋子里(li)(li)(li)進(jin)(jin)行(xing)充(chong)氣(qi)(qi)，但(dan)是(shi)(shi)如(ru)果你的(de)產(chan)(chan)品(pin)是(shi)(shi)粉末狀的(de)就不(bu)能用(yong)起(qi)初一(yi)種(zhong)(zhong)(zhong)方法了(le)(le)，需(xu)要(yao)(yao)(yao)(yao)第二種(zhong)(zhong)(zhong)在真空(kong)室(shi)充(chong)氣(qi)(qi)利(li)用(yong)壓(ya)(ya)力差(cha)(cha)充(chong)滿袋子。可(ke)是(shi)(shi)客(ke)戶(hu)又(you)(you)要(yao)(yao)(yao)(yao)要(yao)(yao)(yao)(yao)求(qiu)達到(dao)(dao)一(yi)定比例的(de)殘(can)氧(yang)量，這(zhe)就很矛(mao)盾(dun)了(le)(le)。
