真空包裝(zhuang)機廠的真(zhen)空(kong)包裝機增加充(chong)(chong)氣(qi)(qi)功能是(shi)(shi)(shi)(shi)有兩種(zhong)(zhong)(zhong)(zhong)方(fang)式，一(yi)(yi)種(zhong)(zhong)(zhong)(zhong)是(shi)(shi)(shi)(shi)氣(qi)(qi)嘴直(zhi)接伸到產品(pin)(pin)袋子(zi)(zi)(zi)里面進行(xing)充(chong)(chong)氣(qi)(qi)的，另一(yi)(yi)種(zhong)(zhong)(zhong)(zhong)是(shi)(shi)(shi)(shi)把要充(chong)(chong)的氣(qi)(qi)體先充(chong)(chong)滿整個真(zhen)空(kong)室，然后靠(kao)負壓差充(chong)(chong)滿袋子(zi)(zi)(zi)。那究竟采用(yong)哪(na)種(zhong)(zhong)(zhong)(zhong)方(fang)式充(chong)(chong)氣(qi)(qi)好(hao)呢，這(zhe)里主要看客戶(hu)的產品(pin)(pin)性質，單純來說肯定是(shi)(shi)(shi)(shi)直(zhi)接沖(chong)到袋子(zi)(zi)(zi)里比較(jiao)好(hao)，這(zhe)樣置換的又純還能省不(bu)少氣(qi)(qi)源，但(dan)是(shi)(shi)(shi)(shi)大(da)家一(yi)(yi)定要考慮好(hao)自己產品(pin)(pin)性質。如果產品(pin)(pin)是(shi)(shi)(shi)(shi)顆粒，我們可(ke)(ke)以(yi)采取起初一(yi)(yi)種(zhong)(zhong)(zhong)(zhong)方(fang)法直(zhi)接讓充(chong)(chong)氣(qi)(qi)嘴到袋子(zi)(zi)(zi)里進行(xing)充(chong)(chong)氣(qi)(qi)，但(dan)是(shi)(shi)(shi)(shi)如果你的產品(pin)(pin)是(shi)(shi)(shi)(shi)粉(fen)末狀的就(jiu)不(bu)能用(yong)起初一(yi)(yi)種(zhong)(zhong)(zhong)(zhong)方(fang)法了(le)，需要第二種(zhong)(zhong)(zhong)(zhong)在真(zhen)空(kong)室充(chong)(chong)氣(qi)(qi)利(li)用(yong)壓力差充(chong)(chong)滿袋子(zi)(zi)(zi)。可(ke)(ke)是(shi)(shi)(shi)(shi)客戶(hu)又要要求(qiu)達(da)到一(yi)(yi)定比例(li)的殘(can)氧量，這(zhe)就(jiu)很(hen)矛盾了(le)。
