真空包(bao)裝機廠的真(zhen)空包裝機增(zeng)加充(chong)氣(qi)(qi)功能(neng)是(shi)(shi)(shi)(shi)有兩種(zhong)方式，一種(zhong)是(shi)(shi)(shi)(shi)氣(qi)(qi)嘴直(zhi)接伸到(dao)產(chan)(chan)(chan)品袋子(zi)(zi)里(li)面進行(xing)充(chong)氣(qi)(qi)的，另一種(zhong)是(shi)(shi)(shi)(shi)把要充(chong)的氣(qi)(qi)體先充(chong)滿(man)(man)整個真(zhen)空室，然后(hou)靠(kao)負(fu)壓(ya)差(cha)充(chong)滿(man)(man)袋子(zi)(zi)。那究(jiu)竟采用哪種(zhong)方式充(chong)氣(qi)(qi)好(hao)呢，這(zhe)里(li)主要看客戶(hu)的產(chan)(chan)(chan)品性質(zhi)，單純來說肯定(ding)(ding)是(shi)(shi)(shi)(shi)直(zhi)接沖到(dao)袋子(zi)(zi)里(li)比(bi)較好(hao)，這(zhe)樣置換的又純還能(neng)省不少氣(qi)(qi)源，但是(shi)(shi)(shi)(shi)大家一定(ding)(ding)要考慮好(hao)自己產(chan)(chan)(chan)品性質(zhi)。如果產(chan)(chan)(chan)品是(shi)(shi)(shi)(shi)顆粒(li)，我們(men)可以采取起初一種(zhong)方法直(zhi)接讓充(chong)氣(qi)(qi)嘴到(dao)袋子(zi)(zi)里(li)進行(xing)充(chong)氣(qi)(qi)，但是(shi)(shi)(shi)(shi)如果你的產(chan)(chan)(chan)品是(shi)(shi)(shi)(shi)粉末狀(zhuang)的就不能(neng)用起初一種(zhong)方法了，需要第二種(zhong)在真(zhen)空室充(chong)氣(qi)(qi)利用壓(ya)力差(cha)充(chong)滿(man)(man)袋子(zi)(zi)。可是(shi)(shi)(shi)(shi)客戶(hu)又要要求達(da)到(dao)一定(ding)(ding)比(bi)例的殘氧量，這(zhe)就很矛盾了。
