真空包裝機廠的(de)真空(kong)包裝機增加充(chong)氣(qi)功能是(shi)有(you)兩種(zhong)(zhong)(zhong)方式(shi)，一(yi)種(zhong)(zhong)(zhong)是(shi)氣(qi)嘴直(zhi)接(jie)(jie)伸到產品(pin)袋(dai)(dai)子里(li)(li)面進行(xing)充(chong)氣(qi)的(de)，另一(yi)種(zhong)(zhong)(zhong)是(shi)把(ba)要(yao)(yao)充(chong)的(de)氣(qi)體(ti)先充(chong)滿整個真空(kong)室，然后(hou)靠負壓差充(chong)滿袋(dai)(dai)子。那究竟(jing)采用哪種(zhong)(zhong)(zhong)方式(shi)充(chong)氣(qi)好(hao)呢，這里(li)(li)主要(yao)(yao)看(kan)客戶的(de)產品(pin)性(xing)質，單純(chun)(chun)來說肯定是(shi)直(zhi)接(jie)(jie)沖到袋(dai)(dai)子里(li)(li)比較好(hao)，這樣置換的(de)又(you)純(chun)(chun)還能省(sheng)不少氣(qi)源，但是(shi)大(da)家一(yi)定要(yao)(yao)考慮好(hao)自己(ji)產品(pin)性(xing)質。如果產品(pin)是(shi)顆粒，我(wo)們可以采取(qu)起初一(yi)種(zhong)(zhong)(zhong)方法直(zhi)接(jie)(jie)讓充(chong)氣(qi)嘴到袋(dai)(dai)子里(li)(li)進行(xing)充(chong)氣(qi)，但是(shi)如果你的(de)產品(pin)是(shi)粉末狀的(de)就不能用起初一(yi)種(zhong)(zhong)(zhong)方法了，需要(yao)(yao)第二種(zhong)(zhong)(zhong)在(zai)真空(kong)室充(chong)氣(qi)利(li)用壓力差充(chong)滿袋(dai)(dai)子。可是(shi)客戶又(you)要(yao)(yao)要(yao)(yao)求達到一(yi)定比例的(de)殘氧量，這就很矛(mao)盾了。
