真空包(bao)裝機廠的(de)(de)真空(kong)包裝機(ji)增(zeng)加充(chong)(chong)(chong)氣(qi)(qi)功(gong)能(neng)是(shi)(shi)有兩種方(fang)(fang)式(shi)，一(yi)(yi)種是(shi)(shi)氣(qi)(qi)嘴直(zhi)接(jie)(jie)伸到產品(pin)(pin)袋子里面進(jin)行(xing)充(chong)(chong)(chong)氣(qi)(qi)的(de)(de)，另一(yi)(yi)種是(shi)(shi)把要(yao)充(chong)(chong)(chong)的(de)(de)氣(qi)(qi)體先充(chong)(chong)(chong)滿整個真空(kong)室，然后靠(kao)負壓差充(chong)(chong)(chong)滿袋子。那究竟采用哪種方(fang)(fang)式(shi)充(chong)(chong)(chong)氣(qi)(qi)好(hao)呢，這(zhe)里主要(yao)看客戶(hu)的(de)(de)產品(pin)(pin)性質(zhi)，單(dan)純(chun)來說肯定是(shi)(shi)直(zhi)接(jie)(jie)沖(chong)到袋子里比較好(hao)，這(zhe)樣置(zhi)換的(de)(de)又(you)(you)純(chun)還能(neng)省(sheng)不少氣(qi)(qi)源，但是(shi)(shi)大家一(yi)(yi)定要(yao)考慮(lv)好(hao)自己產品(pin)(pin)性質(zhi)。如(ru)果(guo)產品(pin)(pin)是(shi)(shi)顆粒，我們可以采取起初一(yi)(yi)種方(fang)(fang)法直(zhi)接(jie)(jie)讓充(chong)(chong)(chong)氣(qi)(qi)嘴到袋子里進(jin)行(xing)充(chong)(chong)(chong)氣(qi)(qi)，但是(shi)(shi)如(ru)果(guo)你的(de)(de)產品(pin)(pin)是(shi)(shi)粉末狀的(de)(de)就不能(neng)用起初一(yi)(yi)種方(fang)(fang)法了(le)(le)，需(xu)要(yao)第二種在真空(kong)室充(chong)(chong)(chong)氣(qi)(qi)利用壓力差充(chong)(chong)(chong)滿袋子。可是(shi)(shi)客戶(hu)又(you)(you)要(yao)要(yao)求達到一(yi)(yi)定比例的(de)(de)殘氧量，這(zhe)就很矛盾了(le)(le)。
