真空(kong)包裝機廠(chang)的(de)真空包裝機增加充(chong)(chong)(chong)氣功能(neng)是(shi)(shi)有兩(liang)種(zhong)方式，一(yi)(yi)種(zhong)是(shi)(shi)氣嘴(zui)直接伸到(dao)產(chan)品(pin)袋(dai)(dai)子(zi)(zi)里(li)面進(jin)行充(chong)(chong)(chong)氣的(de)，另(ling)一(yi)(yi)種(zhong)是(shi)(shi)把要(yao)(yao)充(chong)(chong)(chong)的(de)氣體先充(chong)(chong)(chong)滿整(zheng)個真空室，然后靠負壓(ya)差充(chong)(chong)(chong)滿袋(dai)(dai)子(zi)(zi)。那究(jiu)竟采(cai)用哪(na)種(zhong)方式充(chong)(chong)(chong)氣好(hao)呢，這(zhe)里(li)主(zhu)要(yao)(yao)看客(ke)戶的(de)產(chan)品(pin)性質(zhi)，單純來說(shuo)肯定是(shi)(shi)直接沖到(dao)袋(dai)(dai)子(zi)(zi)里(li)比(bi)較好(hao)，這(zhe)樣置(zhi)換的(de)又純還能(neng)省不少氣源，但(dan)是(shi)(shi)大家(jia)一(yi)(yi)定要(yao)(yao)考慮好(hao)自己產(chan)品(pin)性質(zhi)。如果產(chan)品(pin)是(shi)(shi)顆(ke)粒，我(wo)們可(ke)以(yi)采(cai)取起初一(yi)(yi)種(zhong)方法直接讓(rang)充(chong)(chong)(chong)氣嘴(zui)到(dao)袋(dai)(dai)子(zi)(zi)里(li)進(jin)行充(chong)(chong)(chong)氣，但(dan)是(shi)(shi)如果你的(de)產(chan)品(pin)是(shi)(shi)粉末狀的(de)就(jiu)不能(neng)用起初一(yi)(yi)種(zhong)方法了(le)，需要(yao)(yao)第(di)二(er)種(zhong)在真空室充(chong)(chong)(chong)氣利(li)用壓(ya)力差充(chong)(chong)(chong)滿袋(dai)(dai)子(zi)(zi)。可(ke)是(shi)(shi)客(ke)戶又要(yao)(yao)要(yao)(yao)求(qiu)達到(dao)一(yi)(yi)定比(bi)例的(de)殘氧量，這(zhe)就(jiu)很(hen)矛盾了(le)。
