真空包裝機廠的真(zhen)空(kong)包(bao)裝機增加充(chong)(chong)(chong)(chong)氣功能(neng)(neng)是(shi)(shi)(shi)(shi)(shi)有兩種方式，一(yi)種是(shi)(shi)(shi)(shi)(shi)氣嘴直(zhi)接(jie)伸(shen)到產品袋(dai)子(zi)(zi)里(li)面進行充(chong)(chong)(chong)(chong)氣的，另一(yi)種是(shi)(shi)(shi)(shi)(shi)把要充(chong)(chong)(chong)(chong)的氣體先充(chong)(chong)(chong)(chong)滿(man)整個真(zhen)空(kong)室(shi)，然(ran)后靠負壓(ya)差充(chong)(chong)(chong)(chong)滿(man)袋(dai)子(zi)(zi)。那究竟采(cai)用哪種方式充(chong)(chong)(chong)(chong)氣好(hao)(hao)呢，這里(li)主要看客戶的產品性質，單純來說肯定是(shi)(shi)(shi)(shi)(shi)直(zhi)接(jie)沖(chong)到袋(dai)子(zi)(zi)里(li)比較好(hao)(hao)，這樣置(zhi)換(huan)的又純還能(neng)(neng)省(sheng)不(bu)少氣源，但是(shi)(shi)(shi)(shi)(shi)大家(jia)一(yi)定要考慮好(hao)(hao)自己產品性質。如(ru)果產品是(shi)(shi)(shi)(shi)(shi)顆粒，我們(men)可以采(cai)取起(qi)初(chu)(chu)一(yi)種方法直(zhi)接(jie)讓充(chong)(chong)(chong)(chong)氣嘴到袋(dai)子(zi)(zi)里(li)進行充(chong)(chong)(chong)(chong)氣，但是(shi)(shi)(shi)(shi)(shi)如(ru)果你(ni)的產品是(shi)(shi)(shi)(shi)(shi)粉末(mo)狀(zhuang)的就不(bu)能(neng)(neng)用起(qi)初(chu)(chu)一(yi)種方法了，需要第二(er)種在真(zhen)空(kong)室(shi)充(chong)(chong)(chong)(chong)氣利用壓(ya)力差充(chong)(chong)(chong)(chong)滿(man)袋(dai)子(zi)(zi)。可是(shi)(shi)(shi)(shi)(shi)客戶又要要求達到一(yi)定比例的殘氧量，這就很矛(mao)盾(dun)了。
