真空包裝機廠的真(zhen)空(kong)包(bao)裝機增加(jia)充(chong)(chong)(chong)氣(qi)(qi)功能(neng)是(shi)(shi)有兩種(zhong)方(fang)式(shi)，一(yi)種(zhong)是(shi)(shi)氣(qi)(qi)嘴直接伸到產品袋(dai)(dai)子(zi)里(li)面進(jin)行充(chong)(chong)(chong)氣(qi)(qi)的，另一(yi)種(zhong)是(shi)(shi)把要充(chong)(chong)(chong)的氣(qi)(qi)體先充(chong)(chong)(chong)滿(man)(man)整個真(zhen)空(kong)室(shi)(shi)，然后(hou)靠(kao)負(fu)壓差充(chong)(chong)(chong)滿(man)(man)袋(dai)(dai)子(zi)。那究(jiu)竟采用(yong)(yong)(yong)哪(na)種(zhong)方(fang)式(shi)充(chong)(chong)(chong)氣(qi)(qi)好(hao)呢(ni)，這(zhe)里(li)主要看客戶的產品性(xing)質，單純來說肯(ken)定(ding)是(shi)(shi)直接沖到袋(dai)(dai)子(zi)里(li)比較好(hao)，這(zhe)樣置(zhi)換的又純還能(neng)省(sheng)不少氣(qi)(qi)源，但是(shi)(shi)大家一(yi)定(ding)要考慮好(hao)自(zi)己產品性(xing)質。如(ru)(ru)果產品是(shi)(shi)顆(ke)粒(li)，我們(men)可以采取起初(chu)一(yi)種(zhong)方(fang)法直接讓(rang)充(chong)(chong)(chong)氣(qi)(qi)嘴到袋(dai)(dai)子(zi)里(li)進(jin)行充(chong)(chong)(chong)氣(qi)(qi)，但是(shi)(shi)如(ru)(ru)果你的產品是(shi)(shi)粉(fen)末狀的就不能(neng)用(yong)(yong)(yong)起初(chu)一(yi)種(zhong)方(fang)法了，需要第二種(zhong)在真(zhen)空(kong)室(shi)(shi)充(chong)(chong)(chong)氣(qi)(qi)利用(yong)(yong)(yong)壓力差充(chong)(chong)(chong)滿(man)(man)袋(dai)(dai)子(zi)。可是(shi)(shi)客戶又要要求達到一(yi)定(ding)比例的殘氧量，這(zhe)就很矛盾了。
